The John Guest white polypropylene push-fit reducing straight connector is designed to join two metric pipes or tubes of different sizes. Installation is quick and straightforward, with push-fit technology providing a secure connection and a leak-tight seal—eliminating the need for tools, heat, or sealing agents.

Its precision collet locking system ensures the pipe is held firmly without distortion or restricting flow. These fittings are corrosion-resistant and fully demountable, helping to maintain system performance and minimise downtime during servicing.

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