The John Guest push-fit Stem to Tube Adaptor (Metric to Imperial) is designed to convert imperial or metric pipework to a stem-type connection. Installation is quick and straightforward, with push-fit technology delivering a secure connection and a leak-tight seal—no tools, heat, or sealing agents required.

Its precision-engineered 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 to the highest standards, this adaptor is suitable for foodstuffs, potable liquids, and inert gases. In compliance with the British Beer & Pub Association Code of Practice, it can also be used for 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.
