The John Guest grey push‑fit acetal swivel branch tee (NPTF thread) connects two pipes of the same size and provides an additional swivel NPTF threaded branch connection. Installation is quick and straightforward: the push‑fit design delivers an instant, leak‑tight seal without the need for tools, heat, or sealing compounds.

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

Manufactured from grey push‑fit acetal copolymer, the fitting 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 manufactured and assembled in the UK.
