BES have 22mm with 19mm bore in 30cm length, code 13753, but only
13mm in other lengths. http://www.bes.ltd.uk , watch the vat + post.
However, I don't think a *short* length of reduced bore makes a lot of
difference, a 30cm length of 13mm will have the same restriction as 70cm
of 22mm; if I calculate correctly. 60cm of 13mm == 1.4m of 22mm.




Did JG Speed fit existed around the time of the original OP's post?

We started using the smaller sizes from the mid seventies where they
replaced Enots brass compression fittings for a lot of applications.
The first week we had them the store man got a bit sniffy as
following the general style of the Cadburys Smash Martian which was
on the TV at the time we used a hundred or so fittings to build
something similar with a pressure gauge for a face and put it on his
desk.
Being a typical miserable ******* store man he complained about the
cost "You've just wasted about £50 pounds of fittings "as he was
oblivious that they could be easily separated without damage.
