Description
This adaptor is designed to convert an imperial push-fit tube connection to a female BSP threaded port. It is commonly used in pub cellars and bar installations where beer, beverage or gas lines need to connect into male BSP threaded equipment. The flat end BSP design allows secure connection to threaded components such as regulators, pumps, coolers or other dispense equipment. It provides a clean transition from push-fit tubing to a traditional BSP interface without the need for complex assemblies.
Manufactured from grey acetal copolymer with a nitrile O-ring and EPDM thread seal, the fitting delivers an airtight connection with strong flow characteristics. It is suitable for foodstuffs, potable liquids and inert gases. In accordance with the British Beer and Pub Association Code of Practice, it can be used with N2, CO2 and mixed gas dispense lines, as well as air, pneumatic and vacuum systems.
The push-fit side creates an instant leak tight seal without tools, hot works or sealing agents. The secure collet cover helps prevent accidental disconnection while holding the tube firmly without restricting internal bore. Fully demountable, the adaptor supports efficient maintenance and system upgrades in busy commercial environments.
