The John Guest grey push‑fit acetal tube‑to‑hose stem adaptor provides a simple way to convert a John Guest push‑fit connection into a hose‑type threaded connection. Designed for quick installation, John Guest push‑fit fittings deliver an instant, reliable seal without the need for tools, heat, or sealing compounds.

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

Manufactured from grey push‑fit acetal copolymer, the adaptor is suitable for foodstuffs, potable liquids, and inert gases. In line with the British Beer & Pub Association Code of Practice, it can also be used with N2/CO2 and mixed‑gas dispense systems, as well as air, pneumatic, and vacuum applications. All John Guest fittings are designed and assembled in the UK.
