This adaptor converts metric pipe to an imperial NPTF-threaded connection for attachment to a fitting, fixture, or appliance. 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 unique collet locking design securely holds the pipe in place without causing deformation or restricting flow. These fittings are corrosion-resistant and fully demountable, helping to optimise system performance and minimise downtime during maintenance.

Manufactured from white acetal copolymer with EPDM O-rings, the fitting is suitable for potable water, intermittent hot water applications (up to 65°C maximum), and water treatment or purification systems. All John Guest fittings are manufactured and assembled in the UK.
