The John Guest grey push‑fit acetal straight adaptor (BSPT thread) allows you to connect metric pipe to an imperial BSPT threaded fitting, fixture, or appliance. Designed for quick installation, John Guest push‑fit technology provides an instant, tool‑free connection with a reliable, leak‑tight seal—no hot works or sealing compounds required.

Its advanced collet locking mechanism grips the pipe securely 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 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 lines, as well as air, pneumatic, and vacuum applications. All John Guest fittings are designed and assembled in the UK.
