The bottom line question is this:

Can I use a silicon sealant, like Dow 732, to seal a propane regulator
fitting?

http://www.mcmaster.com/#dow-corning...alants/=i140zh

If not, is there something else that will solve the following problem:

The O-ring on the regulator of my gas grill has gone bad (again). This
is the O-ring that should seal the nipple where it screws into the
regulator itself, having nothing to do with the QCC-1 connection to
the tank. In other words, there is no (or shouldn't be any) movement
at that connection.

I was able to find a replacement O-ring at a mom-and-pop hardware
store few years ago, but I tried a number of different sizes from the
same source last week and I can't get it to seal anymore. I guess
there won't be a $0.50 fix this time.

Yesterday, I bought a replacement regulator and hose from Home Depot
(Brinkman, $17) and it fits fine. However, it leaks at same spot -
where the nipple screws into the regulator. I tried tightening the
nipple with a deep socket over the valve inside the QCC-1 connector
but it didn't budge. It does not appear that there is an O-ring on
this unit like there is on the original.

I plan to exchange the item today on the hopes that the one I have is
defective, but if the replacement leaks also I'm thinking of trying
some silicone sealant at the nipple/regulator junction.

I wouldn't unscrew the nipple...I'd just spread some sealant around
the threads where they enter the regulator.

What I don't know if whether silicon is "propane-proof" or will the
propane eat through the silicon.

Your thoughts? Thanks.

It's not a kludge I'd want to try, particularly, whether I knew the
interaction or not. It "just ain't right" and w/ gas, whether natural
or LP there isn't much room for error even though a seep there isn't
likely to be a major problem, still w/ propane being heavier than air
and all so what does leak doesn't just fly away like NG...

Don't know where you're located but surely there's an industrial supply
that can match the o-ring--here it's the gasket store that goes by the
name "MYHOMETOWN Gasket Supply"...I've never had anything they couldn't
match from tiny garden sprayer nozzle to 6" metal (and that's just
getting started for them for the oilfield folks that are their primary
customer base out here).

Please excuse me if I don’t understand. You say that “The O-ring on the regulator of my gas grill has gone bad” and then you say you “bought a replacement regulator and hose from Home Depot (Brinkman, $17) and it fits fine” Didn’t this new regulator come with a new o ring? And if so then is the new one leaking as well?

Why not go to a real supply house that will have thousands of O rings on
hand? Around here there are two. One is bearings and drives and almost
across the street there is a hydraulic supply place that in addition a
large stock of things like O rings can make pretty much any type of gas
hose needed.

It appears that you did not read my post carefully enough.

As I said regarding the replacment: "It does not appear that there is
an O-ring on this unit like there is on the original."

To clarify...

The grill itself is a BBQ Grillware model from Lowes. Where the nipple
screws into the regulator there is an O-Ring.

The replacement regulator and hose is a Brinkman from Home Depot. As
far as I can tell there is no O-ring at the nipple, at least not a
visible one like on the original.

A replacement regulator/hose for the BBQ Grillware is $36 on-line, the
Brinkman was $17 and it fits the grill perfectly at both ends.

Since the Brinkman was 1/2 the cost and doesn't appear to have an O-
ring that will fail every couple of years like the original, I'd
rather use the Brinkman - unless of course all of the Brinkmans leak
at the junction, in which case I've got a choice I need to make:"

Buy the $36 BBQ Grillware part and hope the O-ring lasts longer than
the last few or seal the junction on the Brinkman - assuming the next
one I buy leaks also.

I have a Grainger store fairly nearby that I could try.

Thing is, the hardware store I went to has a fairly large assortment
of O-rings (60 maybe?) and a couple of years ago I was able to find a
replacement from the same source, going through the same bins. I
brought the nipple and regulator in last week and thought I found a
match. When it didn't worked, I tried 3 other sizes but none of them
worked.

I'm thinking that there may something wrong with the mating surfaces,
so I chose to replace the whole part.

The thing that sucks is that the replacement part leaks in the same
spot! Hopefully it's just a defective item.

I know o-rings are made of different material. Perhaps you are getting

I have been testing it with soap bubbles.

That's how I know that the leak is where the nipple screws into the
regulator.

Take a look at this picture, which only shows the QCC-1 connector and
the threaded portion that screws into the regulator:

http://www.bbqguys.com/item_item_4032.html

The picture shows the threads simply ending at the unthreaded section
of the nipple, which is what the replacement Brinkman part looks like,
but not my original BBQ Grillware part.

My original connector has an indentaion near the unthreaded portion
that an O-ring sits in. Once the connector is threaded into the
regulator and tightened via a socket that fits over the valve inside
the QCC-1 connector, the O-ring sits in a matching indentation on the
regulator. It's this O-ring that has gone bad twice in the last couple
of years and now I can't seem to find a an O-ring that seals the
junction, even though I went back to the same source as before. The
leak is so bad you can hear and feel it coming out, you don't even
need any soap solution.

The replacement part that I bought, which includes the QCC-1
connector, the regulator and the hose to the grill, does not appear to
have an O-ring. A number of threads are still visible outside of the
regulator and it leaks right at the regulator/thread junction. Lot's
of bubbles at the junction, nothing at QCC-1 end of the nipple. It
does not appear to be loose since I am unable to tighten it with my
socket set.

I'm hoping that it is just a faulty part and that an exchange at Home

Well, if the connection it's to fit to was designed for an o-ring then a
part w/o it is certainly not going to fit correctly and seal--that's
pretty much a given.

As said before, find the real industrial distributor in the area, take
the o-ring with you and they'll mic it and find the replacement. When
you do, buy a dozen...

Or replace both ends of the connector w/ a matching design or the
replacement part from the manufacturer. Trying to mix 'n match ain't

wrong part for the specific application.

If you go to the manufacturer's site or look for parts distributors, you
may find the o-ring as a part directly rather than the whole assembly at
Lowes.

You've mis-understood the description of the issue and/or what I
bought as a replacement.

I have purchased a replacement part that is constructed differently
but not in a manner that impacts it's installation or use.

This is an example of the part in question. I have purchased this
entire part, end to end, and installed it as is.

http://ak.buy.com/PI/0/500/206887980.jpg

Note the brass nipple behind the QCC-1 connector that screws into the
input of the regulator.

The original from BBQ Grillware has an O-ring where that nipple screws
into the regulator. The replacement from Brinkman does not use an O-
ring.

Since I am using that entire hose/regulator/QCC-1 combination as is,
the O-ring is no longer involved.

It's not that there is one missing, it's that the manufacturer chose
to design the regulator/nipple connection differently. However, it
doesn't matter since I'm not trying to install a part without an O-
ring where there should be one. I'm not taking the purchased part
apart, I'm simply attaching the brass fitting at the end of the hose
to the flare fitting on the burner control and the QCC-1 connector to
the tank. I am using that entire hose/regulator combination as is.

The problem - perhaps coincidentally - is that the Brinkman part leaks
at the exact same location as the original part - where the nipple
screws into the regulator.

As said before, find the real industrial distributor in the area, take
the o-ring with you and they'll mic it and find the replacement. *When
you do, buy a dozen...

The original O-ring is cut, ripped and dried out. Perhaps it can still
be mic'ed, but it's in pretty bad shape. However, I'm not sure I want
to keep using the original part, even with a new O-ring. It seems like
a bad design to me since the original O-ring went bad in about 3 years
and the replacement lasted about 2. Each time, propane is spewed into
the atmosphere, probably costing more than the $17 replacement hose/
regulator combination. I have another regulator/hose combination for a
huge propane burner and it doesn't use an O-ring at the nipple-
regulator connection. I'll wager that unless you have a BBQ Grillware
grill, you don't have an O-ring on your's either.


Or replace both ends of the connector w/ a matching design or the
replacement part from the manufacturer. *Trying to mix 'n match ain't
gonna' work here--

As described above, there is no mix and match going on here. The QCC-1
connector for the tank is standard, the 5/8" flare fitting on the hose
to the burner control is standard and neither of them leak. It's the
connection between the brass nipple and the regulator on the
replacement part that leaks, a connection that is right off the shelf,
just like you would end up with if you wanted to replace your
regulator/hose/QCC-1 connector as a unit as pictured above.

Had I never mentioned the original part with the O-ring and simply
said "I bought this hose/regulator/QCC-1 combination and it leaks
where the nipple screws into the regulator" it would be the same thing
as I have now. I see now that the mention of the O-ring has confused
the issue.

the part you have isn't defective, it's simply the wrong part for the specific application.

I hope that at this point you'll agree that the part *is* defective
since the O-ring has nothing to do with the part I purchased and is
not missing from any connection.


If you go to the manufacturer's site or look for parts distributors, you
may find the o-ring as a part directly rather than the whole assembly at
Lowes.

Been there, tried that. Even if I could find the O-ring, I don't think
I really want to replace it as I mentioned above. I think it's a bad
design but I can't say that for sure since the Brinkman replacement
part - a part that was designed without an O-ring, also leaks at the
regulator.

Well, what that helps with is the description where the problem is.

Take a look at any of the parts desribed as a "Tailpiece Assembly".
Just so we're all on the same page, we know that the bulbous end goes
into the tank, the smaller threads go into the regulator.

You'll notice that none of the Tailpiece Assemblies shown there have
an O-ring (or an indentation that could hold an O-ring) on the end
that screws into the regulator.

The original part from my BBQ Grillware does, and it's that O-ring
that keeps going bad.

The Brinkman hose/regulator/QCC-1 connector combination that I bought
as a replacement does not have an O-ring at the regulator and I have
installed the hose/regulator/QCC-1 connector combination as a single
unit. Therefore the fact that it leaks at the tailpiece-regulator
connection is not related to a missing O-ring since it wasn't
manufactured with one nor have I disassembled that connection prior to
installation.

I'm really hoping that it's just a bad part (and a bad coincidence)
and once I exchange it, all will be right in my grilling world.

That is a MPT connection. I'd wonder if it was actually assembled
finally as you purchased it. A PT connection needs pipe dope or teflon
tape to seal; if it doesn't have that no wonder it leaks.

That is if I follow your description correctly.

There does (yes) appear to be sealant in the threads of the Brinkman
replacement that I purchased.

So, now that we are both on the same page as far as where the leak is
on the replacement part, let's say I stop by HD on the way home and
exchange the Brinkman for another Brinkman and it still bubbles up my
soap solution at that connection.

Do you think that a layer of Dow 732 silicone sealant will work - and
last?

I'm very familiar with Dow 732 for sealing wet connections as well as
an adhesive that is easily dismantled, but I don't know how it would
hold up for sealing a minor leak at a propane connection.

An NPT connection for a gas fitting is always sealed with pipe dope. If
it is still leaking, as in your replacement, I would bring it back for
an exchange (if I didn't think I could fix it myself). As to your
question about the silicone sealant I would say emphatically NO. Don't
do that. Even if I thought it would work (and I don't) nobody in their
right mind would open themselves up to the potential liability by saying
that yes, that is a good idea (and I don't believe it is).

While you're there (HD) buy a roll of yellow teflon tape if you don't
have any. (It's same thing as the white, just thicker specifically for
gas to take fewer wraps).

If the fitting leaks still, there are only two basic possibilities--
a) it's not tight or is lacking in dope and/or tape, or

b) the regulator threads are oversized or otherwise faulty.

No, do _NOT_ use silicone...

If not, is there something else that will solve the following problem:

The O-ring on the regulator of my gas grill has gone bad (again). This
is the O-ring that should seal the nipple where it screws into the
regulator itself, having nothing to do with the QCC-1 connection to
the tank. In other words, there is no (or shouldn't be any) movement
at that connection.

I was able to find a replacement O-ring at a mom-and-pop hardware
store few years ago, but I tried a number of different sizes from the
same source last week and I can't get it to seal anymore. I guess
there won't be a $0.50 fix this time.

Yesterday, I bought a replacement regulator and hose from Home Depot
(Brinkman, $17) and it fits fine. However, it leaks at same spot -
where the nipple screws into the regulator. I tried tightening the
nipple with a deep socket over the valve inside the QCC-1 connector
but it didn't budge. It does not appear that there is an O-ring on
this unit like there is on the original.

I plan to exchange the item today on the hopes that the one I have is
defective, but if the replacement leaks also I'm thinking of trying
some silicone sealant at the nipple/regulator junction.

I wouldn't unscrew the nipple...I'd just spread some sealant around
the threads where they enter the regulator.

What I don't know if whether silicon is "propane-proof" or will the
propane eat through the silicon.

Your thoughts? Thanks.

I don't thing propane will eat through silicone. *However I would not
rely on silicone to replace an O ring. *Are you proposing to put the
silicone in and then tighten and let it cure? *If so, an O ring is
tough and something
to tighten up against. * Silicone will just squeeze out.

Have you tried going to an appliance/gas grill shop?- Hide quoted text -

- Show quoted text -

No, I was not going to use the silicon as an O-ring. As I said in my
OP, the Brinkman replacement part does not appear to have an O-ring,
at least not a visible one like I have on the original.

Since the Brinkman leaks at the nipple-regulator junction, I was
simply going to spread some silicone on that junction to try and seal
it up.

I have not tried an appliance or gas grill shop. The grill is from
Lowes (BBQ Grillware). My guess is that any replacement regulator and
hose they carry will be much more expensive, but of course, if it
doesn't leak then it's worth it.

I called Lowes and they do carry a replacement hose/regulator for the
BBQ Grillware grills but if it has an O-ring like the original then
I'm reluctant to try it based on my past experience of the O-ring's
going bad. I'll swing by there tonight and take a look.

I saw one of those grills burst into flame once and the leak was at the
hose/regulator. It was not a pretty sight when the hose burned up and
left a stream of flame shooting out of the tank for 8 feet. Either do
it right, or toss the whole thing in the garbage. If a replacment
regulator did not work, then the hose is bad, or both. Replace both or
get a new grill. Gas leaks are not something to play russian roulette
with, which is what you are doing by using things not made for the
application.

The O-ring should last many years as long as you dont keep taking it

Do you really think I grab a socket and take the regulator apart every

Sheesh.

It's a QCC-1 connector. No tools required - until the O-ring goes bad,
which has happened twice in 3 years.

Why not go to a real supply house that will have thousands of O rings on
hand? Around here there are two. One is bearings and drives and almost
across the street there is a hydraulic supply place that in addition a
large stock of things like O rings can make pretty much any type of gas
hose needed.

I know o-rings are made of different material. Perhaps you are getting
o-rings that are made of a rubber material that is affected by propane.

If the part you are talking about looks like the QCC-1 to regulator
connection at
http://www.clagrills.com/grillpartsh...connection.htm
is it possable to wrap the nipple thread with teflon tape and assembly
it to the regulator or use a good pipe dope. The O ring might have
been used in production to cut down on labor, and that is the reason
there is not one on the replacement part. Good luck

The reason that there is no O-ring on the replacement part is because
the replacement part is from a diffeent manufacturer.

In any case, I exchanged the replacement part for another one and this
one does not to leak. The first replacement I bought must have simply
been defective. The cashier marked it as such and tossed it into the
"defective items" bin.

maybe there should be an o-ring and the one that you bought it is
missing that o-ring,

Years ago, I got a gadget that you placed between the tank and the
regulator that had a gauge and promised to help measure how much fuel
was left. (It was a mistake on my part to buy it but ...)

Anyway, I found out that the damn thing started leaking. Problem was
that it didn't have an "O" ring but a custom piece of rubber.

I know it is an old post, but the easy answer to this is to cut your own O-ring out of a sheet of VITON rubber. Only use VITON most other rubbers will degrade from the propane.
