Overview

Feed two large air lines from one metric port with this DOT brass push-lock 3-way adapter distributed by FleetPro Parts & Tires. It threads into an M22 x 1.5 port and provides a 1/2in PLC tube end alongside a 5/8in PLC tube end, giving an International air brake circuit its supply and its branch from a single fitting instead of a stack of bushings and tees. Every joint in a stacked adapter is one more surface that can weep, and those are the leaks that keep a compressor loaded, trip the low-air buzzer and air a truck down overnight. Manufactured by Automann to Fleet Standard specifications, 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.

Big-Line Capacity: The M22 3-Way Adapter Advantage

Both outlets are push-lock (PLC), which matters most on heavy 1/2in and 5/8in DOT nylon tubing โ€” stiff line that is genuinely difficult to assemble with compression nuts in a tight chassis, but that seats with a straight push here and locks. Sharing one sealed M22 x 1.5 thread between both outlets keeps the port count down and the flow path short.

The brass body handles the moisture, oil carryover and road salt that live in a heavy-duty air system, and this adapter is DOT-approved for heavy-duty air brake systems and meets FMVSS 571.106, so it belongs in a service or emergency circuit rather than only on shop air. At FleetPro Parts & Tires, we know the right adapter ends the leak chase. This Automann adapter replaces 177.55960 and is a direct replacement for the highly searched industry number IHC 3819960C1.

Key features
  • Two Large Outlets, One Port: A 1/2in and a 5/8in push-lock tube end share a single M22 x 1.5 thread instead of a bushing-and-tee stack.
  • Easy on Stiff Heavy Line: 1/2in and 5/8in DOT nylon tubing is awkward to assemble with compression nuts, but seats here with a straight push.
  • Fewer Joints to Weep: Consolidating an adapter stack into one body removes the sealing surfaces that keep a compressor loaded and a truck airing down.
  • Correct M22 x 1.5 Metric Thread: Matches the International metric port, so nothing is forced or cross-threaded on installation.
  • DOT / FMVSS 571.106 Compliant: Brass construction approved for heavy-duty air brake systems, legal in service and emergency circuits.
