Overview
Branch a 3/8 in air line without threading anything with this PLC Y Union distributed by FleetPro Parts & Tires. All three legs are push-to-connect and all three take 3/8 in DOT nylon tubing, so a supply run can be split to feed a second circuit using nothing but square-cut tube ends. The alternative โ a threaded tee with pipe nipples and sealant on every joint โ adds three more places to develop the slow leak that drains the tanks overnight and has a driver chasing a hiss before dawn. 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.
Three Legs, No Threads: The 3/8 in PLC Y Union Advantage
This Y union is a composite body with a brass collet and it fits 3/8in x 3/8in x 3/8in tube. Because it is a Y rather than a square tee, the branch leaves the body on an angle, which keeps the split lines running with the existing routing instead of forcing a hard bend at the fitting. That is the difference between a clean loom along the frame rail and a pair of stressed elbows that chafe on the first bracket they touch.
Assembly is the same on every leg: cut the tubing square, push it fully home, and tug-test each one before airing the system up. At FleetPro Parts & Tires, this Y union is a direct replacement for highly searched industry numbers including Fairview CPC1464Y-6, Freightliner 23-14401-001, Parker 362PTC-6 and Phillips 12-96066. It also replaces the older Automann number 177.12C63666 โ order this one if that is the number on your list.
