Overview

Keep a tire inflation equipped trailer wheel end sealed with this PSI Hub Cap distributed by FleetPro Parts & Tires. It is the tire inflation system ready cap for Meritor TP and WP and Hendrickson HP axles running oil, and it closes the wheel end while the inflation system does its work. When one of these caps cracks or its gasket gives up, you lose hub oil and inflation pressure at the same time, and the trailer will keep giving you trouble 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 Meritor TP/WP 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 cut off, and with a magnetic side fill plug that picks up ferrous debris out of the oil where it can be seen at the next service.

The cloud free window is what makes this cap worth having. A milky window tells a driver nothing on a pre-trip, while a clear one turns the hub oil level check into a two second look. Together with the included gasket, this cap gives you a Meritor TP/WP or Hendrickson HP trailer wheel end that can actually be inspected instead of assumed.

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 31439-00, Stemco 343-4372 and Globetech GT-4372S.
