Description
This fitting is designed to convert an imperial push-fit tube connection into a female BSP flat end tap interface. It is typically used in pub and bar environments where beer or beverage lines must connect directly to tap shanks or threaded dispense hardware with a flat sealing face. The flat end configuration provides a stable sealing surface against compatible male BSP tap components. This makes it particularly suitable for installations where a washer or flat-faced seal is required rather than a tapered engagement.
Manufactured from grey acetal copolymer with a nitrile O-ring and EPDM thread seal, the adaptor delivers an airtight connection with strong flow characteristics. It is suitable for potable liquids, foodstuffs 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 tube end creates an instant leak-tight seal without tools, hot works or sealing agents. The secure collet cover helps prevent accidental disconnection while holding tubing firmly without restricting internal bore, supporting consistent pressure and pour quality across drinks dispense systems. Fully demountable, it allows efficient servicing and tap replacement in commercial settings.
What is the difference between this and the standard Tap Adaptor (BSP Thread)?
The key difference is the flat end threaded design.
-
The standard tap adaptor connects to a female BSP tap connection using a conventional threaded interface.
-
The flat end version is designed to seal against a flat-faced male BSP tap shank, typically using a washer or flat sealing surface.
In practical terms, the flat end adaptor is used where the tap assembly requires a flat sealing face rather than relying on thread engagement alone. This ensures correct alignment and reliable sealing in specific pub tap configurations.
