Overview

Metric ports are where a good air-line repair usually goes sideways. This PLC 45 degree swivel male elbow distributed by FleetPro Parts & Tires solves it directly: an M22x1.5 O-Ring male end into the component port, a push-lock tube end for 1/2in DOT nylon tubing, and a 45 degree swivel body so the line leaves at the angle the routing wants. Improvising with adapters stacks two more leak paths onto a brake circuit that already has to hold pressure all night, and every extra joint is one more thing an inspector can find weeping. 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.

Metric Port, Correct Fitting: The M22 Swivel Elbow Advantage

The M22x1.5 O-Ring end seals on the O-ring face rather than on thread interference, so it seats consistently without being cranked down hard. On the other end, push-lock assembly means a square-cut tube pushed into the collet until it bottoms - the brass collet holds it and seals it, no flare tool, no ferrule, no second trip. The composite body carries that brass collet, keeping the elbow light while the sealing surfaces stay metal where it counts. Combined with the 45 degree swivel, you can torque the port end properly and still turn the tube to face the run.

It is DOT-approved for heavy-duty air brake systems and meets FMVSS 571.106, so it belongs on the brake circuit rather than in the general shop-air drawer. This Automann fitting is a direct replacement for Parker 379PTCR-8-MA22, also written 379PTCR8MA22.

Key features
  • Correct Metric Port: An M22x1.5 O-Ring male end mates the component port directly instead of stacking adapters and extra leak paths.
  • O-Ring Face Seal: The O-ring does the sealing, so the fitting seats consistently without being torqued into thread interference.
  • 45 Degree Swivel: Tighten the port end properly, then rotate the tube port so 1/2in nylon line leaves at the angle the routing needs.
  • Push-Lock Tube End: Square-cut the tube, push it home, and the brass collet grips and seals it with no flare tool on the road.
  • FMVSS 571.106 Compliant: DOT-approved for heavy-duty air brake systems, so it is legal where it counts.
