Smooth Barb Elbow

John Guest elbow with smooth stem

Family of 90° connectors for joining a smooth stem to a tube line through a push-fit connection. Available in several size combinations for adapting components and tubing in confined spaces.

Selection

Variants combine smooth stems and tubes of different diameters, including 3/16", 1/4", 5/16", 3/8" and 1/2" depending on option. Check which size corresponds to each side.

Practical use

It lets the connection outlet be oriented without forcing the tube and is useful in dispensing equipment with limited space around valves, cooling coils or accessories.

Installation

With the circuit depressurized, confirm the sizes, prepare the tube with a square cut and fit without lateral loads. Perform a leak test after connection.
