John Guest white push‑fit acetal bulkhead connector designed for through‑wall installations, allowing the connection of pipes in unequal sizes. The push‑fit design enables quick, tool‑free installation, creating an instant, leak‑tight seal without the need for hot works or sealing compounds.

Its unique collet locking mechanism securely grips the pipe without causing deformation or restricting flow. The fittings are corrosion‑resistant and fully demountable, helping to maintain system performance and minimise downtime during servicing.

Manufactured from white push‑fit acetal copolymer with EPDM O‑Rings, this fitting is suitable for potable water, intermittent hot water applications (up to 65°C), and water treatment or purification systems. All John Guest fittings are produced and assembled in the UK.
