Description
This reducing elbow is designed to connect two unequal imperial OD tubes while forming a precise 90° bend. It is commonly used in pub cellars and behind-bar installations where beer or beverage lines need to change direction and reduce in size within a confined layout. This fitting allows installers to step down from larger supply lines to smaller product or gas feeds without introducing threaded adaptors or additional components. It supports clean, compact pipe routing around coolers, python systems, bar fonts, and dispense equipment.
Manufactured from rigid grey acetal copolymer, it delivers reliable mechanical performance in busy commercial environments. The material is suitable for potable liquids, foodstuffs and inert gases. In line 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 mechanism creates an instant leak tight seal without tools, hot works or sealing agents. Its integrated collet locking system holds the tube securely without deforming it or restricting the internal bore, helping maintain consistent pressure and pour quality across beer and beverage systems. Fully demountable, it allows rapid line changes, upgrades or servicing with minimal downtime.
