Description
This fitting converts an imperial push-fit tube connection to a female NPTF threaded interface. It is ideal for pub and bar installations using US specification equipment requiring NPTF connections. This adaptor provides a clean transition from beer or beverage tubing to male NPTF threaded components such as regulators, pumps, chillers or dispense assemblies. The flat end design ensures a secure threaded engagement while maintaining compact installation geometry in cellar environments.
Manufactured from grey acetal copolymer with a nitrile O-ring, 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 on 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 design helps prevent accidental disconnection while retaining the tube without restricting internal bore, supporting consistent pressure and pour performance in drinks dispense systems. Fully demountable, it enables efficient maintenance and straightforward equipment replacement.
