The John Guest push‑fit tap adaptor (UNS thread) provides a straightforward way to connect pipe or tubing to a UNS‑type threaded connection. Designed for quick, tool‑free installation, John Guest push‑fit technology delivers an instant, secure joint with a leak‑tight seal—without the need for heat, tools, or sealing compounds.

Its precision‑engineered collet‑locking mechanism grips the pipe firmly without deforming it or restricting flow. The fittings are corrosion‑resistant and fully demountable, helping to maintain system performance and reduce downtime during maintenance.

Manufactured from grey push‑fit acetal copolymer, the adaptor is suitable for foodstuffs, potable liquids, and inert gases. In accordance 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.
