Metal O.D. wall type - Acrylic rubber and fluorine rubber, fluorosilicone rubber, perfluoro rubber, etc.
- 5. Quality Matters While price is important, it's equally crucial to consider the quality of the car oil seal you're purchasing. Investing in a higher-quality seal may be more expensive upfront, but it will likely save you money in the long run by reducing the need for frequent replacements.
This is almost similar to that of ‘A’ type seal. But this has the metal case placed outside. When the housing is rough, temperature is high and working conditions are severe, this type is preferred
Is the seal you need not available from one of our standard ranges? No problem. We design and supply seals in any material, size and quantity - from very small to very large volumes.

When selecting a natural rubber gasket for your specific application, there are several key factors to consider. The first is the hardness of the gasket, which is typically measured on the Shore A scale. A softer gasket (lower Shore A hardness) is more flexible and better suited for applications where the sealing surface is uneven, while a harder gasket (higher Shore A hardness) provides better resistance to compression and extrusion.
An oil seal type that is resistant to oils, fuels, and solvents, fluorosilicone also offers temperature stability. Primarily found in aerospace fuel applications and automotive fuel emission control, this o ring material is fast becoming popular in more and more oil-based applications across a wide spectrum of industries.
2) Special seal types and their features
Refit all the components in the reverse order of dismantling.

Operating conditions such as the engine’s temperature, position, size, pressure and shaft speed largely determine which individual oil seal composition is most suitable for every individual application.
