Description
Designed to create a 90° swivel connection between two John Guest push-fit fittings, this fitting enables flexible directional changes within beer and beverage dispense systems while maintaining a secure push-fit seal. This configuration is particularly useful in pub cellars and behind-bar installations where equipment movement, tight routing or connection alignment requires a degree of rotational flexibility. The stem design allows one fitting to connect directly into another push-fit component, forming a compact and adaptable elbow assembly.
Manufactured from rigid grey acetal copolymer, the fitting 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. Its construction supports reliable performance in chilled cellar environments and high-use bar installations.
The push-fit mechanism delivers an instant leak tight seal without tools, sealants or hot works. The integrated collet locking system grips the tube securely without deforming it or restricting internal bore, helping maintain consistent pressure and steady pour performance across beer and beverage lines. Fully demountable, it allows rapid maintenance, line changes or system upgrades with minimal disruption.
