PSI Thru-Tee Assembly Dual Wheels - 5in Automatic Tire Inflation Hose - Meritor 3131704 177.T17041

Keep the automatic tire inflation system doing its job with this PSI Thru-Tee Assembly distributed by FleetPro Parts & Tires. It is the 5in thru-tee hose assembly that ties the inflation plumbing into both tires of a dual-wheel end. When a thru-tee splits, chafes through or leaks at a fitting, the system bleeds air continuously, the inflation hardware runs to keep up, and the duals you were counting on it to protect quietly go flat instead. 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.

Both Duals Covered: The PSI Thru-Tee Assembly Advantage

An automatic tire inflation system is only as good as the plumbing at the wheel end. This thru-tee assembly is the piece that carries air through to both tire positions on a dual, which is why a single failed tee can take an entire wheel end out of the system. Replacing it restores the circuit instead of leaving one tire riding on whatever pressure it had the last time somebody checked it.

The 5in length is the correct size for the dual-wheel installation, so the assembly is not stretched tight across the wheel end and not left long enough to chafe on rotating hardware. At FleetPro Parts & Tires, we know a wheel-end repair is only right when the part is the right part. This Automann assembly is a direct replacement for highly searched industry numbers including Meritor 3131704, Meritor 31317-04 and Freightliner TDA3131704.
