22mm compression fittings: spanners required?
Stephen
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

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 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.

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

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'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.

Annoys me too! I've got some Screwfix vouchers that I might put towards
a decent set now you've given me the idea. I did have a friend recommend
me to get some Bahco ones but I'd already sort of ended up with Stilsons
as my default plumbing tool as they were the best thing I had. The
adjustable spanners I've had before have been utter pants and the comedy
bicycle-spanner style compression nut spanner is a nonsense.

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,
http://www.alloy-artifacts.com/Photos/tools/barnes_adj_5in_wrench_bicycle_f_cropped_inset.jpg
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.

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.

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

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.

Got into a very difficult bit of the loft yesterday to fit a reducing T

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.

I'm surprised by this, since the pipes they fit are standard sizes, I
assumed the fittings would be standard sizes too.
If someone made a fitting bigger than necessary/other makes, it would
cost them more, so I can't see any manufacturer doing that. If a
fitting required a different spanner to most other fittings, surely
people would not buy the unusual sized fitting because of that
inconvenience?
That said, the nuts on my Horstmann 2-port valves seem to be one
millimetre bigger than those on any other 22mm fitting in my house.
The truly awful Monument spanner[*] that is supposed to fit 15mm and
22mm fittings at either end, will not fit the nuts on the valve.
BTW, what's all this about Stilsons being used on pipes. How do you/

If you're screwing a malleable iron fitting on a steel pipe you will
most certainly need to grip the pipe.

15mm and 1/2" are quite close: 22mm and 3/4" ain't. But it's the threads
on compression fittings which are BSP - only the bore and olive sizes were
altered for metric tube.

Pipe wrenches are used for threaded galvanised pipes. These are still
used in many areas. I've just installed an outside water supply which
used galvanised pipe.

to say:
ISTR that the _original_ size for BSW spanners was 1�D + 1/8" (where D
is of course the bolt diameter), and that this was reduced a bit
during WW2 to economise on metal.

Hah! It's plumbing we're talking about here. We should count ourselves
lucky that most compression nuts are a fairly standard size (note I said
'fairly', not consistently), so the centre hex portion of a joint is
whatever the maker wants it to be.

Half inch is near enough to 12.5 mm. 2 1/2 mm smaller than 15 mm
22mm and 3/4" ain't.
3/4 inch is near enough to 19 mm. 3 mm smaller.

1 & 1/8th works out to 28.6 mm, which looks about right for the OP.
About 20 years ago I bought some spanners with obscure sizes and only
now am I understanding why they were made. One of them was 29 mm, but I
can't remember the others and it is dark and cold where they are stored :-)

Metric sizes are the outside diameter of the tube whereas imperial is the
bore. And the wall thickness of imperial tube is usually greater than
metric. In other words few could identify 15mm against 1/2" without
measuring it - but you can between 22mm and 3/4"

I bought a set in Aldi (possibly Lidl) a couple of years ago. Stiltson
wrench, set of water pump ish pliers designed to do up compression wastes -
really useful and a pair of water pump pliers. The latter had one jaw going
through the other rather that laying on top - IYSWIM.
Anywho, never slips, best I've ever used & whole set cheap as chips.
