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 sealing lip makes contact with the rotating shaft, creating a barrier that effectively retains lubricants while blocking unwanted particles. The design may include additional features such as garter springs to maintain contact with the shaft and improve sealing effectiveness over time.
2. Fire Resistance Fiberglass shingles offer superior fire resistance compared to many other roofing materials. The fiberglass content helps prevent flame spread, providing an added level of safety for your home. This fire-resistant quality may also lead to lower homeowner's insurance rates, adding to their appeal.
