22mm compression fittings: spanners required?
 
Hello,

What size spanners do you need for 22mm straight compression fittings?
The nuts are 32mm but what about the flange on the middle of the body?
I measured it with a vernier calliper and I think it was 28.5mm, which
seems an awkward size. Rounding that up to 29mm, I could not find any
29mm spanners anywhere. Would a 30mm spanner be too big or do you
"cheat" and use adjustable ones?

Thanks,
Stephen

Sorry to post to myself; I hit send too soon.

I also have to dismantle a leaky and very old pillar tap. I measured
that and the flange is 34mm wide so I need to buy something that is
that wide (fixed or adjustable).

I do have stilsons and adjustable spanners but they stop at about 30mm
(and are only marked up to 25mm). It seems most spanner sets only go
up to 24mm, so for 22mm plumbing a new set of spanners is required.
Why don't sets include these sizes? Surely they must be used often, or
is it that all the professionals solder?

Screwfix used to sell a big Hilka spanner set up to 32mm (IIRC) but I
had three or four sent to me and all were rusty on arrival, so all got
sent back. Any recommendations on what and where to buy or not buy?

I guess the tap needs a new washer and or reseating.

Thanks,
Stephen.

I bought two of these:

http://www.screwfix.com/prods/38428/...table-Wrench-8

Having messed about with other tools, these are the biz for firmly
tightening compression fittings (even in awkward locations) without
tearing the corners off the fittings.

Opens to about 42mm IIRC.

I always end up with Stilsons when plumbing - usually two pairs. I've
always wanted some 'proper' spanners and keep meaning to make a list of
sizes to take to a car boot - I suspect a lot of the sizes required are
imperial/Whitworth ones.

Nothing "cheating" about using adjustable spanners :) Unless space is tight
and you need a slim normal spanner.

A good quality Bahco in a couple of sizes deals with many evils.

I find pipe grips invaluable. They will adjust and grab many hexagonal
shapes, radiator valve bodies etc. Plus they have narrow(ish) jaws so will
fit where stilsons won't.
A set of these and 2 or three shifter sizes will cover a lot of plumbing
jobs.
You don't need to apply ridiculous leverage even to make up a 22mm
compression joint, so as long as you have a pretty firm grip these are a
must

What make does it fit? The nuts are all different from maker to maker.

One of these which is brill as it locks - Stanley lockable adjustable smooth
jaws. About £20, but seen one for £10 at a tool stall once:

Don't forget that compression fittings are BSP sized, therefore the
correct spanners will (or should be) imperial size.

I'd say it might also depend on the make of fitting - some still seem to
use the old imperial sizes on the body. Luckily I have a fair selection of
such spanners so just use one that fits.

This chart might help you guess what it is :-

Trouble is Stilsons usually mark the fitting which annoys me - they have
jaws for dripping round things so have to cut in. A good quality
adjustable is better.

I find stillsons awkward on 15mm fittings, and spanners not very
useful.

I usually hold the centre of the fitting (T piece or elbow) with an F
pattern adjustable,

it's good for clearance where a 'normal' adjustable won't go.

Other way is to spend some time at car boot ales or autojumbles etc and
get some old BSF/Whitworth spanners. They're not much in demand so don't
fetch much. A fixed correct sized spanner is always better than an
adjustable.

Or a "water pump" spanner, narrower jaws than most adjustables so they fit
OK on the central hexagon, but still have the Stillson "self-locking"
property provided you have them the right way round.

I agree you need to be selective where you (can) use them.
For seized solid old fittings smothered in boss white they're a non-starter
and will do damage. But for assembling new stuff and used carefully they're
fine.

That is my plan. I've got a few largish imperial spanners that sometimes
come in handy for plumbing but I've never sat down and worked out
exactly what I should be looking for. It only occurs to me when I'm
stood in field and see a nice big box of old tools :-(

If you check the site I gave earlier you can convert the actual across
flats measurement into what BSF etc spanners are marked as. So you know
what to look out for.

I agree you need to be selective where you (can) use them.
For seized solid old fittings smothered in boss white they're a
non-starter and will do damage. But for assembling new stuff and used
carefully they're fine.


Once again!!! They chew up fittings! Only use on pipes!!!!! What they are
designed for.

I find pipe grips invaluable. They will adjust and grab many
hexagonal shapes, radiator valve bodies etc. Plus they have
narrow(ish) jaws so will fit where stilsons won't.

And chew up fittings!

Got into a very difficult bit of the loft yesterday to fit a reducing T
for a new shower supply. Discovered I had not got my usual spanners with
me. Managed fine with mole wrench and adjustable pliers/pipe wrench. Was
in a low pressure situation though and with ptfe tape on the threads.

Don't forget that compression fittings are BSP sized, therefore the
correct spanners will (or should be) imperial size.


I did wonder that when I measured 28.5mm but then I thought if the
pipe is metric, surely the fittings will be too; I was forgetting that
15 and 22 mm pipe are essentially 1/2 and 3/4 inch pipe.
