Marketing InformationJohn Guest® push-fit polypropylene tap adaptor (UNS thread) fitting connects pipe/tubing to a tap connection point. 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 acetyl and is suitable for potable water (10 bar at 20 deg C) and intermittent hot water applications (4 bar at 60 deg C), as well as water treatment and purification applications. All John Guest® fittings are manufactured and assembled in the UK.
