John Guest Drinks Grey Acetal Stem Adaptor BSP

The John Guest grey acetal push-fit stem adaptor (BSP Thread) is designed to quickly convert a push-fit connection to a BSP threaded connection, making it ideal for drinks dispense, gas supply, and potable water systems. Commonly used in pubs, bars and cellar installations, this adaptor allows seamless integration between John Guest tubing and BSP-threaded components such as keg couplers, manifolds, and dispense equipment.

Manufactured from strong acetal copolymer with a nitrile thread seal, the fitting provides an airtight, leak-tight connection with excellent flow characteristics. The integrated collet locking design securely grips LLDPE or soft metal tubing without deforming the pipe or restricting flow, ensuring reliable long-term performance in beverage and gas applications. Installation is fast and tool-free; simply push the tube fully into the fitting to create an instant seal. The connection is fully demountable without tools, making servicing, system modifications and maintenance straightforward while reducing downtime in commercial dispense environments.

Suitable for potable liquids, food grade liquids, inert gases and vacuum applications, this adaptor is compliant with the British Beer & Pub Association Code of Practice for use with N2/CO2 and mixed gas lines. All John Guest fittings are manufactured and assembled in the UK, providing consistent quality and performance.
