Composite Bulkhead Union 45 Deg - DOT 1/2" Push-to-Connect Air Brake - IHC 2029565C1 177.12C45BH8

Take an air line through a bracket or panel and turn it on its way with this Composite Bulkhead Union, 45 Degree distributed by FleetPro Parts & Tires. It joins PLC 1/2in DOT Nylon Tubing x PLC 1/2in DOT Nylon Tubing and puts a 45 degree turn in the run as it does it, so a 1/2 in line clears a crossmember or bracket instead of being forced into a bend it was never meant to take. A kinked nylon air line is where the next breakdown starts — the tube collapses at the bend, then chafes through against the steel it was wrapped around. 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.

Routing Without a Kink: The 45 Degree Bulkhead Union Advantage

A bulkhead union carries the tubing run through a panel or bracket and leaves a serviceable joint right at the wall, so the next technician can break the line at a known point instead of cutting into a harness bundle. This one is a composite body fitting with push-to-connect terminations on both ends, sized for 1/2 in DOT nylon air-brake tubing. Cut the tube square, push it in, and the collet holds — no flare, no threading and no sealant on the tube side of the joint.

The 45 degree geometry is the part that saves the install. Where a straight union would force the line into a hard bend the moment it clears the panel, this fitting starts the turn inside the fitting body and lets the tubing leave on the angle it needs. At FleetPro Parts & Tires, this union is a direct replacement for the highly searched industry number IHC 2029565C1, and it replaces the older Automann number 177.12C45BH88 — order this one if that is the number on your parts list.
