Brass Push-Lock Male Elbow - 1/2" Tube x 3/8" NPT 90 Degree DOT Air Brake Fitting - Replaces Eaton 1869X8 177.13B158C

Run a big 1/2 in supply line into a 3/8 in NPT male port and still make the bend cleanly with this DOT brass push-to-connect male elbow distributed by FleetPro Parts & Tires. Half-inch tubing is stiff, and forcing it around a corner with the wrong fitting is how lines end up kinked at the compressor discharge, the wet tank or the dryer. Once a 1/2 in circuit starts leaking, the whole truck is slow to build and slow to release. 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.

High-Volume Supply Lines: The 1/2 in Brass PLC Elbow Advantage

This 90 degree elbow pairs a 1/2 in push-to-connect tube end with a 3/8 in NPT male pipe thread, the combination used all over the primary supply side of a tractor's air system. The brass body and collet handle the heat and vibration found near the compressor and dryer far better than lightweight substitutes, and the fitting is built to FMVSS 571.106 / DOT requirements for brake circuits.

Assembly stays simple even on the larger tube: cut the nylon line square, push it fully home, and the collet does the gripping and the sealing. The part weighs 0.13 lbs and ships in a 1.6 x 1.5 x 0.9 in package, small enough that a shop can stock every common size on one shelf.

At FleetPro Parts & Tires, we know the supply side is where an air leak hurts most. This Automann fitting is a direct replacement for highly searched industry numbers including Eaton 1869X8 and Parker 169PMTNS86. Every unit ships new and is backed by the 1-Year FleetPro Warranty.
