Valve cover gaskets and head gaskets play pivotal roles in maintaining the proper functioning of the engine. The valve cover gasket prevents oil leaks and contaminants from compromising the lubrication and performance of the engine, while the head gasket ensures the proper sealing of the combustion chamber, allowing for efficient fuel combustion and preventing the mixing of oil and coolant. Both gaskets are critical for the overall efficiency, performance, and reliability of the engine.
- Valve oil seals are a crucial component of an internal combustion engine. These small but important parts play a vital role in ensuring the engine operates smoothly and efficiently.
- Global economic conditions also have a significant impact on oil seal prices. Economic recessions can lead to decreased demand for oil seals as businesses cut back on expenses, while economic booms can increase demand as industries expand and require more oil seals. Additionally, fluctuations in currency exchange rates can affect the price of imported oil seals, as the value of the local currency relative to other currencies can impact the cost of raw materials and transportation.
- In the realm of automotive technology, the advent of spark plugs has revolutionized the internal combustion engine, enhancing its efficiency, performance, and overall reliability. These tiny devices, no larger than a thumbnail, play a crucial role in igniting the air-fuel mixture within the engine's combustion chamber, thereby initiating the power stroke that propels the vehicle forward.
- However, it's worth noting that despite their many strengths, PTFE oil seals have their limitations. They may not be as suitable for high-speed applications due to their relatively low tensile strength and creep resistance. Nonetheless, these limitations are often countered by incorporating additional materials or design modifications.
Cassette seals are designed to maximise grease or oil retention and protection against liquid or solid contaminants. These seals are provided with their own bushings in which dirt is kept out and oil/grease kept in by a multi-lip seal.
In conclusion, the piston oil seal is a critical component in an internal combustion engine. It plays a vital role in preventing oil leakage, reducing friction, and ensuring efficient engine operation. Regular inspection and maintenance of the piston oil seal are essential for maintaining the performance and longevity of the engine.



Most ERIKS oil seals, such as the types M, MST, R and RST, are made of NBR as standard.

oil seal in motor. They are specially engineered to provide a tight seal that can withstand the rigors of daily use. Without proper oil seals, the motor can suffer from oil leaks, reduced efficiency, and ultimately, complete breakdown.
The material of the sealing lip is chosen according to the liquid to be sealed and the rotational speed. For larger shafts, an NBR sealing lip can cope with surface speeds of up to 10-12 m/s, while an FKM lip is suitable for speeds of up to 35-38 m/s.


Where loads are light, the outer skin layer can be made of silicone. It can be made of Fluroelastomer (orViton) to protect under high temperatures (more than 120 degrees Celcius). The skin can also be made of Poly Acrylate or Polytetra-FluroEthylene.
These seals are more commonly used in pumps, motors both electric & hydraulic, gearboxes & occasionally dirt wipers in hydraulic cylinders. They help protect shafts and bearings from dirt and harmful contaminants entering the internals of the application that they are fitted to, as well as prevent any leaks of lubricant.
