Universal Adaptor Kit 15 x 21mm is rated 1.4 out of 5 by 11.
Rated 1 out of 5 by from The sizes do not work MDPE 25mm perfect but the transition side does not cover up to 27mm I put a vernier on the collar which come out at 21.67mm now if they are say the MDPE side is 27mm that make no sense as Poly comes in 25 or 32???

Rated 1 out of 5 by from Doesn't quite seal - avoid! Don't do what I did and assume other reviewers weren't assembling this correctly. I needed to join the old imperial 1/2" Class C/D rising main (external O.D 21mm) to 15mm copper or PE. As this is a 21mm X 15mm coupler I took the chance that it would fit the 1/2" pipework as the metric measurements for this one and it's larger cousin (27mm) correspond exactly to Imperial PE pipework, so that must be what it's designed to do. Never found out if it fitted the 1/2" pipe as the supposedly simple bit, the 15mm doesn't connect securely, it's almost tight enough but I tried with 15mm copper and 15mm PE and both can turn in the connection even when cranked up as tight as possible. I can only assume this is poor manufacturing tolerances, but whatever the reason it renders this coupler absolutely useless so don't waste your money. If you need to make a connection to 1/2" imperial most of the big manufacturers make couplers to 20mm MDPE, which is what I'm going to order now.

Rated 1 out of 5 by from Not universal. Would only accept 22mm. I'm a plumber and have used various universal couplers. This is useless.
