Choosing and using the proper sealing devices within oil and gas applications can be vital when preventing dirt, dust, water, and other debris from potentially getting inside and contaminating products.
Rubber valve cover gaskets are crucial components in automotive engines, serving to create a secure seal between the valve cover and the cylinder head. These gaskets prevent oil leaks and contaminants from entering the engine, ensuring proper lubrication and protection of critical components. High-quality rubber valve cover gaskets are essential for maintaining the integrity and performance of the engine, contributing to optimal engine operation and reliability.



ERIKS type M (type B according to the DIN standard) has a single metal casing and rubber sealing lip. Since the casing is made of metal, it must be fitted in a well-finished, undamaged groove. Large volumes of oil seals with metal casings are often cheaper, which is why they are often used as original equipment in machines. However, if an oil seal has to be replaced, types with a rubber exterior (type R or RST) are easier to fit. Type MST is similar to M and commonly used. The difference is the dust lip in the MST oil seal that prevents dust and dirt reaching the sealing lip, and extends its service life in dusty environments.
Auto Oil Seal:
Viton Oil Seals - A synthetic rubber and fluoropolymer elastomer, Viton is used to make oil seals that provide resistance in both high temperature, up to 250°C and low compression set components. They also offer a high resistance to chemicals and abrasions, so they can be used in elements that regularly interact with petroleum and solvents.
Regular inspection and maintenance of oil seals are essential to identify signs of wear, damage, or leakage. Proper lubrication and adherence to recommended service intervals can help extend the lifespan of oil seals. When replacement is necessary, selecting the correct seal type and ensuring proper installation are critical to maintaining the integrity and performance of the equipment.
To install them, both correctly and professionally, it is essential to use the right special tool for the replacement part. We recommend replacing this component with the aid of OE repair manuals with complete and extensive instructions.
