Rated 3 out of 5 by from Compression, not soldered! I needed to reduce from 22 mm to 15 mm to fit a 22 mm compression auto-bypass valve on an existing 15 mm pipe in a confined space in an airing cupboard (as I couldn't source a 15 mm auto-bypass valve). Having never used one of these before (apart from a set previously supplied with a rad valve) It took me a while to work out how to assemble it to the fitting! Even then, once I'd worked out how it went in the fitting (less the original olive, as stated by others) as nothing in either the item catalogue description (online or hard-copy) or indeed the packaging, stated whether it was a compression, or soldered fitting, I could see no other way to secure it to the 15 mm pipe other than soldering it on, before assembling the fitting (and remembering to ensure the fitting nut was on the pipe, prior to soldering the reducer on!). It all worked fine (eventually) but initially had an issue (weep) with regard a small blob of solder which i hadn't fully wiped from the end of the reducer which sealed at the nut end! Eventually sorted after some judicious filing, after first draining-down again! 'All seemed like a lot of bother until (after the event!) i checked the 'online' reviews!! 'Wish I'd read them first! Who feels stupid now!

Rated 5 out of 5 by from Cheaper to use this than a Tee This got me out of a problem in a tight airing cupboard where I could not use a soldered fitting and was cheaper to use with a standard TEE Than buying the special 22x22x15mm TEE

Rated 4 out of 5 by from Works OK, tighten fully I read through several reviews before using this compression fitting to take a 22mm elbow down to accept a 15mm copper pipe. You do not use an olive, this reducer does that job, so you can put the 22mm olive from the compression fitting to one side for another job. I put some of the excellent Fernox LS-X around the reducer then put the reducer into the 22mm fitting, then pushed in the 15mm pipe. Some Fernox LS-X or liquid PTFE on the compression fitting threads then tighten but for it to work you do need to hear the 'click' as the ring let's go, then tighten a bit more.

Rated 1 out of 5 by from Pants I bought these to replace used ones on a pressure reducing valve. Impossible to get a water tight seal! Fitting reducers worked perfectly first time, lesson learned.

Can I use this reducung set to reduce a 22mm radiator tail to couple to a 15mm valve (compression fitting)?

I am replacing my old valves with Drayton TRV4s - some of the existing tails are 22mm not 15mm
Asked by: MidnightCowboy
Hello MidnightCowboy, This product would reduce the radiator from 22mm down to 15mm and would be suitable for use. Thank you for using Q & A.
