John Guest black push-fit acetal tube-to-hose stem fitting converts a John Guest push-fit connection into a hose-type threaded connection. Quick and easy to install, John Guest push-fit fittings provide an instant connection and a leak-tight seal without the need for tools, hot works, or sealing compounds.

The unique collet locking design ensures the pipe is held securely without deformation or restriction of flow. These fittings are corrosion-resistant and fully demountable, helping to improve system performance and minimise downtime during maintenance.

Manufactured from acetal copolymer with a food-grade nitrile O-Ring, the fitting is suitable for foodstuffs, potable liquids, and inert gases. In accordance with the British Beer & Pub Association Code of Practice, fittings 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 manufactured and assembled in the UK.
