SKF PSI/MTIS Trailer Hub Cap Oil Fill - Meritor TN/TQ & Hendrickson HN Spindle - Meritor 31427-00 Stemco 343-4370 180.CR1846

Keep an automatic tire inflation wheel end sealed with this PSI Hub Cap distributed by FleetPro Parts & Tires. It is the tire inflation system ready cap for Meritor TN and TQ and Hendrickson HN spindles running oil, and it closes the wheel end while the inflation system does its job. A cracked cap or a tired gasket in this position costs you hub oil and inflation pressure at the same time, and no amount of chasing the trailer will fix it until the cap is right. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, trailer repair shops, and owner-operators nationwide.

Inflation Ready, Oil Tight: The PSI Hub Cap Advantage

This is an OE grade SKF cap supplied as a complete service kit rather than a bare casting. It ships with coated mounting bolts and a gasket, so the cap goes back on with fresh hardware instead of the corroded bolts you just fought off, and with a magnetic side fill plug that picks up ferrous debris out of the oil where you can actually see it at the next service.

The cloud free window is the part a driver uses every day. A hub cap window that has gone milky is worthless on a pre-trip, and a clear one turns an oil level check into a two second look. Between the window, the magnetic plug and the included gasket, this cap gives you a Meritor TN/TQ or Hendrickson HN trailer wheel end you can actually inspect.

At FleetPro Parts & Tires, we know an inflation system is only as good as the wheel end it is bolted to. This SKF cap is a direct replacement for highly searched industry numbers including Meritor 31427-00, Stemco 343-4370 and Globetech GT-4370S.
