Hub Caps

PSI™ Hub Caps

STEMCO has engineered the P.S.I. hub cap designed to meet the specific performance expectations of each fleet, all in an effort to maximize performance and value.

Features

STEMCO MTIS/PSI™ hub caps are available in both oil and grease hub caps for several popular applications. The oil hub caps (343-4370, 343-4371 and 343-4372) have a side fill plug and a standard window with oil fill lines. The grease hub caps (340-4370, 340-4371 and 340-4372) do not have a side fill plug and incorporate a gray opaque window with no markings.

The PSI™ tee fitting and flapper valve are to be installed in the center of the hub cap and are available from Meritor or PSI™ as a part of the PSI™ system. For more information regarding the PSI™ System, contact PSI™ at (210) 222-1926.

The Aluminum STEMCO hub cap has provided safe and secure wheel end protection for over 60 years.
