1/4 in. x 1/4 in. Double Barb x Male Elbow
Overview
The MPN 11857 is a brass 90-degree double mini barb elbow that connects a 1/4 in. double-barb tubing run to a 1/4 in. Male NPT (1/4-18) thread. The dual-barb stem grips poly tubing more securely than a single barb, making it a good choice for vibration-prone right-angle transitions.
