or otherwise known as a M+F,while we are on the subject why are they not a standard 21.5 mm? there a big difference in overflow sizes some brands fit others but lots dont interfit

Centerbrand is horrible - fitting has a slip of about 2.15mm for tube to fix into.

Yeah that and you need a re mortgage to buy a complete bag of fittings

is there a 22mm x 21.5 mm coupling, I had some that did the job, not sure if they were meant to do it!!! so annoying when you get to a job and its 22mm, instead of 21.5.
especially on vaillants, where they are glued on and the idiot installer has put 22mm onto 21.5mm fitting
