You can buy hoses suitable for connecting a propane tank to a bar-b-que at any propane distributor. Maybe you can just butcher two such hoses to make a propane bottle to propane bottle transfer hose.

Most U-Haul locations fill propane tanks by the gallon. The price per
gallon will vary (widely) by location, but near me the per gallon
price times the number of gallons to fill an empty tank is very close
to the one-price-fits-all cost to refill a tank (even a half-full one)
at BJ's Wholesale. In other words, BJ's charges you full price first
and then fills your tank. No refund if you only need half a tank. U-
Haul fills your tank and then charges you only for what you needed.

Just take all of your tanks to U-Haul and get them topped off at the
per gallon price.

However, if you are dead set on transferring the gas from one tank to
another, maybe you can do something with the following info...

I have no idea if this could be used for your application, but when we
camped a lot, I used to this to fill the 1 lb propane canisters from
my 20 lb tank:

http://www.amazon.com/dp/B000AMC5WO

I recall that I would turn the 20 lb tank over and let her rip. I
don't think it filled the 1 lb canisters all the way, but it sure was
cheaper than buying new 1 pounders before each camping trip.

To use this for 20 lb to 20 lb transfer, you might need some more
adaptors and a hose, at which point, unless you are doing it quite
frequenly, you'll never recover the cost of the equipment vs. simply
paying full price to fill to fill your tanks (assuming no U-Hauls in
the area).

Thanks for the idea, but that gadget won't be any help.

What about my U-Haul suggestion (apparently snipped) that you top off the tanks on a price-per-gallon basis?

That sure seems like the easiest and most cost effective solution.

Perhaps this is just an exercise in creative problem solving with no need for an actual, practical solution?

That means making more trips to the store with part full tanks.

Umm...let's see...maybe take all of the partially full tanks in be trip?

Wow! What a concept!

People don't understand what you're trying to do. There is no need to be a dick about it.

You just say "transfer." TO WHAT? A 1lb tank? Another 20lb tank? A larger stationary tank?

RV dealers sell high-pressure hoses with the tank connections, but without regulators for about $20 each, so all you'd need is a brass coupling from Home Depot to connect two of them together.

It's still not going to work: As soon as you tip the source tank over the OPD closes off the valve. You won't be able to transfer the liquid by gravity, and you won't be able to achieve a cold enough temperature on the destination tank using means available to you to "suck" the gas in and turn it back to liquid.

The only way to transfer is with a pump. You'd be $$$ ahead just venting the leftover propane to atmosphere so you can go to the refiller with an empty tank.

You don't need to vent it. The refiller will fill a partial tank. He'll still probably charge you for a full tank. Take it to a real propane store that sells it by the gallon in which case you pay for what you need.

Like U-Haul, which I suggested early on, but haven't yet seen an
acknowledgment of.

I'd prefer not to vent off the last of the propane. Just wasteful, is how I view that. I know of one propane fill that sells by the gallon.

One of the fellows I talked to today, says that some propane companies fill on the spot. I'd seen that done with 100 pound tanks and 100 gallon tanks. Not sure anyone will come out to fill eight 30 pounders. Have to make some calls and ask.

One of the challenging aspects of text format, you lose the inflections and tone of voice. There's no need to accuse a matter of fact, logical person of being a dick.

I don't know one way or the other about the OPD tank, have to try it some day. As I understand, when the float goes "up" towards the valve, it closes. With the tank upside down, the float would go "up" which is now away from the tank valve. That might be open, with tank dispensing liquid.

Look at http://www.nashwauk.net/UnderstandingOPDValves.html

It will not restrict flow when inverted if a proper POL connector is
connected.

No there isn't. If you were being matter-of-fact and logical I wouldn't have.

But, you were clearly having a conniption fit because people weren't answering your exact question exactly the way you wanted it exactly answered. That by definition is being a dick.

The problem is no matter how much you stomp your feet and hold your breath and insist that people tell you what you want to hear, what you want cannot be done. There is simply no way to connect two 30lb tanks together and transfer all the propane out of one into the other without an expensive pump setup.

You understand incorrectly.

It is not a float. It is a "sink" as in it moves toward the pull of gravity.. When the tank is upright it drops away from the tank valve and allows propane to flow.

With the tank upside down it would again go "down" which is now toward the tank valve.

It's more trouble than it's worth. Just hook them up to your grill and finish them off.

I seriously doubt it, the liability would be too high.

They do, however, sell a POL fitting that goes into the big tank (left
handed thread) and converts it to NPT (I have one on an empty bottle I
use as a portable compressed air tank). With some ingenuity, it would
not be very hard to buy two of them, and whatever other fittings you
need to do what you are setting out to do.

http://www.suremarineservice.com/20MP4POL.aspx
http://www.gashosesandregulators.com/brassfittings.html (look at part
204051)

One idea would be to connect the thing in the first link to the thing in
the second link (with a coupler, or find a POL - FPT), but you can
probably come up with something better than that.
