However, it’s plagued with a few drawbacks, such as poor resistance to ozone, sunlight, and weather. It also has limited resistance to high temperatures and flames.
- A well-designed and properly installed 6.0% 20Valve Cover Gasket is essential for optimal engine performance and longevity. When this gasket fails, it can lead to a range of issues, including oil leaks, coolant leaks, and even engine damage. Oil leaks, in particular, can cause serious problems as they can contaminate the engine oil, leading to reduced lubrication and ultimately causing engine failure.
The basic principle of sealing is straightforward – the flexible lip is held against the rotating part (usually the shaft) whilst the casing (or O.D.) is pressed into the housing or bore and holds the seal in place. The sealing lip needs some form of lubrication to avoid overheating and is usually energized by means of a garter spring.
18 No. - Overall, a thin rubber gasket may be a small component, but its importance should not be underestimated. It plays a critical role in sealing applications across various industries, ensuring the safe and efficient operation of equipment. By choosing high-quality gaskets and designing them to meet specific requirements, manufacturers can improve the performance and longevity of their products.
No. Minor lip required
When they are subjected to hot & pressured oil, or hot & pressured gas, they will compress. These seals reduce in size and become more compact. Afterward, they store the mechanical energy generated by the heat and pressure, which is why they can maintain a leak-proof mating surface.
In addition to these standardised types, the following special types are also available:


Lift out the rags without dropping dirt into the engine, bores or passages.
• Rubber material
• Seal type, etc.
Nitrile rubber offers good durability for general use, while the flexibility of the spring behind the sealing lip keeps the oil seal firmly in place against the moving part.

oil seal 50 * 72 * 10.
Common materials used in oil seals include nitrile rubber, fluorine rubber, silicone rubber, acrylic rubber, polyurethane, polytetrafluoroethylene, etc. When selecting the material of the oil seal, the compatibility of the material with the working medium, the adaptability to the working temperature range and the ability of the lip to follow the rotating shaft at high speed must be considered. When the oil seal is working, the temperature of its lip is higher than the working medium temperature by 20~50°C. Attention should be paid when selecting the oil seal material. The working range of the oil seal is related to the material used for the oil seal: the material is nitrile rubber (-40~120°C), Aggreko rubber (ACM) -30~180°C, fluorine rubber (FPM) -25~300°C.
