The John Guest grey push‑fit acetal outlet adaptor (parallel thread) provides a simple way to connect metric pipework to an imperial BSP parallel threaded fitting, fixture, or appliance. Designed for quick installation, John Guest push‑fit technology delivers an instant, secure connection with a leak‑tight seal—without tools, heat, or sealing compounds.

Its engineered collet‑locking system grips the pipe firmly without causing deformation or restricting flow. The fittings are corrosion‑resistant and fully demountable, helping to enhance 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 is also approved for use 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.
