Shaft oil seals typically consist of a flexible sealing lip made from elastomeric materials such as rubber, polyurethane, or silicone, encased in a sturdy outer shell.

The design may include additional features such as garter springs to maintain contact with the shaft and improve sealing effectiveness over time.

Fiberglass is known for its exceptional durability. Unlike traditional materials, fiberglass tread covers are resistant to fading, scratching, and chipping. This quality means that once installed, they require minimal maintenance over time. Simply cleaning the surface with mild soap and water is usually enough to keep them looking new. This low-maintenance aspect is especially beneficial for businesses looking to reduce long-term upkeep costs.
