The John Guest push-fit polypropylene bulkhead connector is designed for creating secure through‑wall connections using imperial pipe. Its push‑fit mechanism allows fast, straightforward installation, forming an instant, leak‑tight seal without the need for tools, heat, or sealing compounds.

A unique collet‑locking system grips the pipe firmly without causing deformation or restricting flow. The fittings are corrosion‑resistant and fully demountable, helping to optimise system performance and minimise downtime during maintenance.

Manufactured from polypropylene and fitted with EPDM O‑rings, this connector provides enhanced chemical resistance compared with acetal push‑fit fittings. It is suitable for potable water systems (10 bar at 20°C), intermittent hot water applications (4 bar at 60°C), and a wide range of water treatment and purification uses. All John Guest fittings are produced and assembled in the UK.
