Engine oil seals are vital components in the automotive engine system, designed to prevent the leakage of lubricating oil and the ingress of contaminants. These seals play a critical role in maintaining the proper lubrication of the engine components, including the crankshaft, camshaft, and other critical parts. Engine oil seals contribute to the efficiency and longevity of the engine by preventing oil leaks and ensuring optimal performance.
- One of the primary functions of an oil seal is to prevent the leakage of oil from the engine, transmission, or hydraulic system. This is crucial because oil is the lifeblood of these systems, providing lubrication, cooling, and cleaning agents that are essential for optimal performance. A leak can lead to reduced efficiency, increased wear, and even catastrophic failure if not addressed promptly.
High- and low-temperature-resistant type
The head gasket and valve cover gasket are critical components in the engine's sealing system. The head gasket seals the cylinder head to the engine block, while the valve cover gasket seals the valve cover to the cylinder head. Both gaskets play pivotal roles in maintaining the integrity and functionality of the engine, preventing oil leaks and ensuring the proper sealing of the combustion chamber.
Garter Spring
Air side face The oil seal surface vertical to the center line of the shaft on the side that does not come in contact with substances to be sealed is called the back face.

By far, nitrile is the most popularly used, but buyers who need seals for applications involving high-speed shaft rotation increased interest. Viton is another alternative for silicone and poly-acrylic because it’s more resistant to harmful chemicals and abrasion and works better in higher temperatures.
Fluid Types - Various oil seals are able to withstand interactions with oils, fuels, grease, water and more. Knowing what type of fluid the rotary shaft seal will be in constant contact with will ensure the longevity of the seal and surrounding components.
