Default Title
£4.99 ex. VAT £4.16
Overview ✕

The 12mm John Guest PP shut off valve PPMSV041212W is a compact push-fit isolation valve for 12mm OD plastic or soft metal tubing. It features Speedfit‑to‑Speedfit push-fit connections on both ends, allowing fast, tool‑free installation into caravan, motorhome, campervan and water filter pipework. A quarter‑turn blue lever handle provides positive on/off control to isolate appliances, taps, filters or individual circuit branches for service and maintenance. The durable white polypropylene body with EPDM O‑ring offers excellent chemical resistance and is suitable for potable water, intermittent hot water and water treatment applications up to 10 bar at 20°C. Fully demountable push‑fit ends make it simple to reconfigure pipe runs or replace components without cutting the tube, helping to minimise downtime.
