The STEMCO 3-5/8" hub cap gasket ensures a reliable seal to prevent lubricant leakage from the hub, constructed from durable materials designed to withstand harsh conditions. It effectively reduces the risk of contamination, thereby enhancing hub longevity and maintaining consistent pressure even in varying temperatures. By effectively trapping lubrication within the hub, it minimizes maintenance needs, contributing to the efficient performance and durability of its vehicle's hub system.
