Overview
Maintain the integrity of your wheel-end lubrication system with the SKF PSI Hub Cap for Meritor and Hendrickson axles. Engineered as a genuine Original Equipment (OE) solution, this heavy-duty aluminum hubcap is specifically designed for trailers equipped with automatic Tire Inflation Systems (PSI). Whether you are servicing a long-haul trailer on the driver side or the passenger side, this hub cap provides a superior seal to prevent grease leakage and contaminant intrusion.
Advanced Protection: The SKF PSI Hub Cap Advantage
The SKF PSI Hub Cap (Automann Part # 180.CR1898) is precision-machined for Meritor TP/WP and Hendrickson HP axles. Optimized for grease applications, it features specialized "cloud-free" window technology, allowing maintenance crews to quickly inspect lubricant levels and condition without removing the cap. Note: This unit comes as a complete installation kit, including a high-quality gasket and coated mounting bolts designed to resist corrosion in the harshest road environments.
As we continue to build the largest inventory of commercial truck parts in Illinois, we prioritize OE-standard components that extend wheel-end life. This hubcap is a direct professional-grade replacement for Meritor 3143700, Stemco 340-4372, and Globetech GT-4372. Don’t compromise your trailer's uptime with inferior seals; choose the SKF standard to keep your fleet moving and your tire inflation system functioning at peak efficiency.
