John Guest 15mm Push-fit Reducer x 18mm Stem

John Guest black push-fit acetal reducer fitting reduces a John Guest push-fit connection port. Fast and simple to install, John Guest push-fit fittings create an instant push-fit connection and leak tight seal without the need for tools, hot works or sealing agents.
The unique collet locking design firmly and securely holds the pipe in place without deforming the pipe or restricting flow. Fittings are corrosion resistant and fully demountable, improving system performance and reducing system downtime during maintenance.

Made from acetal copolymer with a food-grade nitrile O-Ring, the fitting is suitable for foodstuff, 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.
