Valve Cover Gasket for Sale: Ensuring Engine Integrity and Performance
On most cars you need not remove the engine to get at the sump . But often you have to raise it slightly and wedge it on its mountings so that the sump moves clear of the front- suspension cross member.
Leather is probably the oldest of the lip materials still in common use, but the move towards mass production methods has seen a massive increase in the development of synthetic rubbers which lend themselves to accurate and repeatable injection and compression moulding. Nitrile (NBR) is still by far the most common elastomer for “normal” use, whilst Viton® (FKM/FPM) is rapidly replacing Polyacrylate (ACM) and Silicone (VMQ) for high-temperature applications. Viton® also has high resistance to abrasion and chemical attack making it a preferred elastomer. Recent developments in the use of PTFE for Rotary shaft seals has caused widespread interest particularly for high-speed shaft rotation or poor lubrication applications.
Several prominent companies specialize in the manufacturing of oil seals, offering a wide range of sealing solutions for industrial and automotive applications. These companies leverage advanced manufacturing capabilities, extensive research and development, and a deep understanding of industry-specific requirements to produce high-quality oil seals. Leading companies in the oil seal manufacturing sector are known for their commitment to innovation, quality, and customer satisfaction, providing reliable sealing solutions for critical components in machinery and vehicles.

The major cause of extrusion and nibbling is stress caused by high pressure. This is commonly noticed when the oil seal has a chipped or nibbled look. In fact, in some cases, the surface of the seal tends to peel on its own, which makes it have a shaved look. What the stress does is that it increases the clearance gap between the mating edges, which causes the seal to get entrapped, and then leads to severe physical damage.


Classical oil seals consist of a metal housing that carries the dynamic sealing lip and provides the static sealing function. These are usually manufactured of elastomer material, such as ACM, Silicone or FPM. Further, since they are in contact with the surface of the rotating shaft, the lip is pressed onto the shaft surface by means of a spring ring.
