The John Guest grey push‑fit acetal reducing straight connector is designed to join two pipes of different sizes. Engineered for quick and easy installation, John Guest push‑fit technology provides an instant, secure connection with a leak‑tight seal—without the need for tools, heat, or sealing compounds.

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

Manufactured from grey push‑fit acetal copolymer, the connector 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 systems, as well as air, pneumatic, and vacuum applications. All John Guest fittings are designed and assembled in the UK.
