Standard Schedule 40 \/ Class D UPVC pipe is sized by nominal bore, so a 20 mm nominal pipe typically has an O.D. of approximately 25 mm — the fitting socket is machined to accept that O.D.

Apply primer to both the pipe end and fitting socket, then apply cement to both surfaces and push the pipe firmly into the socket with a quarter-turn. Initial set typically takes 15–30 minutes; allow a full 24 hours before pressurising the system.
