Brass Push-to-Connect (PLC) Male Swivel Elbow - 5/8" Tube x M22 x 1.5 - Volvo 20378449 Haldex APM69S10XM22 177.13B6910M22

Turn a tight corner in the air plumbing without kinking the line using this Brass Push-to-Connect (PLC) Male Swivel Elbow distributed by FleetPro Parts & Tires. It takes 5/8 in DOT nylon air brake tubing into an M22 x 1.5 metric port, so the large-diameter supply line can change direction right at the component instead of being bent into a stress riser. A kinked or chafed line and a weeping elbow both end the same way — pressure that bleeds off overnight, a compressor that never catches up, and an audible leak on a brake circuit that puts 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.

Aim the Line, Not the Fitting: The M22 Swivel Elbow Advantage

The value of a swivel elbow is that the thread and the tube port are independent. You seat the M22 x 1.5 male thread properly first, then rotate the elbow to aim the tube run exactly where it needs to go — without twisting the nylon tubing to reach it and without backing the thread off a half turn to get the angle. On a metric port this matters even more, because there is no adapter stack to absorb a bad angle. The fitting itself is a DOT-approved brass air fitting, so salt spray and washdown chemistry do not seize it into the component.

Built for 5/8 in DOT nylon tubing, this is one of the larger push-to-connect sizes, used where air volume matters and a restriction is expensive. It meets FMVSS 571.106 and DOT requirements for brake circuits, which is what makes it legal to leave in the line rather than a temporary fix.

At FleetPro Parts & Tires, we know a metric fitting is only useful if you can find it by the number in your hand. This elbow is a direct replacement for highly searched industry numbers including Volvo 20378449 and Haldex APM69S10XM22, and it supersedes Automann 177.V20378449. Order it as 177.13B6910M22.
