The John Guest push-fit polypropylene reducing tee is designed to connect two pipes or tubes of differing sizes, with a reduced branch outlet. Quick and easy to install, John Guest push-fit fittings deliver an instant connection and a leak-tight seal—without the need for tools, heat, or sealing compounds.

Utilising a unique collet locking mechanism, the fitting securely holds the pipe in place without causing deformation or restricting flow. These fittings are corrosion resistant and fully demountable, helping to enhance system performance and minimise downtime during maintenance.

Manufactured from polypropylene and fitted with EPDM O-rings, this component offers superior chemical resistance compared to push-fit acetal. It is suitable for potable water systems (rated at 10 bar at 20°C) and intermittent hot water applications (rated at 4 bar at 60°C), including water treatment and purification systems. All John Guest fittings are proudly manufactured and assembled in the UK.
