John Guest push-fit polypropylene reducing straight connector fitting connects two pipes of an unequal connection size. 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.

Manufactured in polypropylene with EPDM O-Rings, the fitting offers greater chemical resistance than push-fit acetal and is suitable for potable water (10 bar at 20°C) and intermittent hot water applications (4 bar at 60°C), as well as water treatment and purification applications. All John Guest fittings are manufactured and assembled in the UK.
