Description
This reducing tee is designed to connect two equal imperial OD tubes along the main run while providing a reduced branch outlet. It is commonly used in pub cellars and behind-bar installations where a primary beer or beverage feed needs to supply a smaller secondary line. This configuration allows installers to maintain full bore flow along the main line while introducing a controlled branch connection for ancillary equipment, secondary fonts or gas feeds. It supports structured pipe layouts around coolers, python systems and dispense equipment without the need for threaded adaptors or complex assemblies.
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 with N2, CO2 and mixed gas dispense lines, as well as air, pneumatic and vacuum systems. Its construction performs reliably in chilled cellar environments and high-use commercial settings.
The push-fit mechanism creates an instant leak tight seal without tools, hot works or sealing agents. The integrated collet locking system secures tubing without deformation or flow restriction, helping maintain stable pressure and consistent pour quality across both the main line and branch. Fully demountable, the fitting allows straightforward system alterations and maintenance with minimal disruption.
