Protect your wheel end and maintain your automatic inflation system with the PSI Tire Inflation Hub Cap by SKF. This Original Equipment (OE) aluminum hub cap is specifically designed for trailers equipped with the Meritor Tire Inflation System (MTIS) by PSI. Engineered for grease applications on Meritor TN/TQ and Hendrickson HN axles, it serves as the critical housing for the thru-tee assembly. Whether you are servicing the driver side or the passenger side, this hub cap ensures a contamination-free environment for your wheel bearings.

Durable Aluminum Engineering: The PSI Tire Inflation Hub Cap Advantage

The PSI Tire Inflation Hub Cap (Automann Part # 180.CR1845) is manufactured from high-grade cast aluminum to dissipate heat efficiently and resist corrosion. It features specialized "Cloud Free" technology, allowing for instant visual inspections of grease levels and condition without removing the cap. Note: This hub cap comes as a complete kit, including a precision-cut gasket and coated mounting bolts, ensuring a leak-proof seal against road moisture and debris on both sides of your trailer.

As we continue to build the largest inventory of commercial truck and trailer parts in Illinois, we prioritize OE-grade components that reduce maintenance downtime. This unit is a direct professional-grade replacement for Meritor 3142600, Stemco 340-4370, and SKF 1845. Replacing a cracked or pitted hub cap with this genuine SKF component prevents grease leakage and costly spindle damage, keeping your fleet DOT-compliant and road-ready.
