The John Guest push-fit polypropylene female adaptor with NPTF thread is designed to connect pipe or tubing to an NPTF type threaded connection. Quick and easy to install, John Guest push-fit fittings provide an instant connection and a leak-tight seal without the need for tools, hot works, or sealing compounds. 

The innovative collet locking system ensures the pipe is held securely without deformation or restriction of flow. These fittings are corrosion-resistant and fully demountable, helping to optimise system performance and minimise downtime during maintenance. 

Manufactured in polypropylene with EPDM O-rings, the fitting offers enhanced chemical resistance compared to 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 systems. All John Guest fittings are manufactured and assembled in the UK.
