Brass Push-to-Connect (PLC) Male Swivel Elbow - 3/4" Tube x M22 x 1.5 - Volvo 20462691 IHC 3826347C1 177.13B6912M22

Route the largest air line on the truck around a corner cleanly with this Brass Push-to-Connect (PLC) Male Swivel Elbow distributed by FleetPro Parts & Tires. It accepts 3/4 in DOT nylon air brake tubing and threads into an M22 x 1.5 metric port, letting a heavy supply line turn right at the component instead of being bent into a kink that chokes flow and cracks later. A weeping elbow or a collapsed line on the supply side means a compressor that never gets ahead, pressure that is gone by morning, and an audible leak on a brake circuit that will take a truck out of service at the scale. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.

Full-Volume Air, Around the Corner: The 3/4 in M22 Swivel Elbow Advantage

Because the thread end swivels independently of the tube port, you can torque the M22 x 1.5 male thread home properly and only then rotate the elbow to aim the tube run. No twisting the nylon line to reach the port, and no backing off a good thread to chase an angle. At 3/4 in this is the largest of the common push-to-connect tube sizes, where an unnecessary bend or a partially seated fitting is felt directly as slower recovery time.

The body is a DOT-approved brass air fitting, so it will not corrode into the component the way plated steel does after a few seasons of road salt and washdowns. It meets FMVSS 571.106 and DOT requirements for brake circuits, which is what qualifies it to stay in the line permanently rather than serve as a get-home repair.
