white polypropylene push-fit reducing straight connector fitting connects two unequal metric sized pipes/tubes. Fast and simple to install, 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 seals, the fitting offers greater chemical resistance than push-fit acetal and is suitable for potable water (10 bar at 20C) and intermittent hot water applications (4 bar at 60C), including water treatment applications. All fittings are manufactured and assembled in the UK. John Guest 15mm Female to 12mm Female Reducer PPM201512W in White
