These 15mm John Guest Speedfit stop ends PSE4615W provide a quick, reliable way to cap off 15mm pipework at termination points, either temporarily or permanently. The push-fit design lets you install and demount in seconds without tools – simply push fully onto the pipe and, when needed, push the collet towards the body to release. Compatible with copper, Speedfit PEX and polybutylene barrier pipe (with appropriate inserts), they are suitable for hot and cold water services and central heating systems. Lead free, non‑toxic plastic construction resists corrosion and scale build‑up, helping maintain clean, trouble‑free pipework. Supplied as a pack of 2 stop ends, they are ideal for pressure testing, isolating sections of pipe, or safely restoring the water supply when a job is paused overnight.
