This adaptor converts imperial pipe to an imperial BSP-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 deforming it or restricting flow. These fittings are corrosion-resistant and fully demountable, helping to optimise system performance and minimise downtime during maintenance.

Manufactured from grey acetal copolymer, the fitting is suitable for foodstuffs, potable liquids, and inert gases. In accordance with the British Beer & Pub Association Code of Practice, these fittings can also be used with N₂/CO₂ and mixed gas dispense lines, as well as air, pneumatic, and vacuum applications. All John Guest fittings are manufactured and assembled in the UK.

Note: The 3/8" x 1/4" version includes a special large seal suited for use with chamfered face ports. No thread seal is supplied for the 3/8" x 1/8" version.
