- - Replace the gasket according to the manufacturer's recommendations or when it shows signs of wear or damage.
- The TC type oil seal is named for its unique design, which consists of a lip that comes into contact with the shaft or housing to prevent the escape of fluids. This lip is typically made of a flexible material that can conform to the shape of the moving parts, ensuring a secure seal. The TC type oil seal is typically used in applications where shaft rotation is present, such as in engines, gearboxes, and pumps.
Are you looking to keep your machinery free from any unwanted leakages but aren’t sure which rotary shaft seal is right for your needs? This guide will provide you with everything you need to know in order to select the right one for your application.
- The primary function of an oil seal turbo is to prevent the leakage of oil from the turbocharger bearing system while simultaneously allowing the passage of air or exhaust gases. This dual-purpose design is crucial as it maintains the optimal oil pressure required for the turbo's bearings to rotate smoothly, thus preventing premature wear and tear.
- Prevent entry of dust and foreign matter (dirt, water, metal powder, etc.) from outside
- In conclusion, the rear valve cover gasket, though seemingly insignificant, is a critical part of an engine's health. Its function is not just to prevent oil leaks but also to maintain the cleanliness and lubrication necessary for smooth engine operation. Hence, understanding its importance and ensuring its proper maintenance is a must for every vehicle owner or mechanic. Remember, prevention is always better than cure, and a healthy engine starts with a reliable rear valve cover gasket.
- Die-cut rubber gaskets are commonly used in automotive, aerospace, industrial, and manufacturing industries for sealing purposes. They are crucial for maintaining the integrity of mechanical systems and ensuring their smooth operation. In automobiles, rubber gaskets are used in engines, transmissions, and fuel systems to prevent the leakage of oil, coolant, or fuel. They are also used in doors, windows, and sunroofs to provide a weather-tight seal and reduce noise and vibration.
The mating surfaces of the head or block must be perfectly clean, flat and smooth.
- Low temperature tolerant.



In choosing the right oil seal type for your application, it is essential to assess factors such as speed, temperature range, pressure levels, chemical compatibility, shaft material, and installation space limitations. By considering these factors carefully, you can ensure that you select an oil seal that will provide optimal performance and longevity in your specific application.

How do oil seals work?
2. Oil seal structure and functions
Oil seals go by many names, such as shaft seals, dirt seals, grease seals, lip seals, and many other variations of these. They are essentially simple devices used in rotary shaft equipment to prevent lubricant from escaping and for excluding contaminants such as dust, dirt and water. An oil seal’s most important function, however, is that it protects every type of ball, sleeve and roller bearing in the rotating shafts. The seals also prevent the integration of two different fluids that shouldn’t mix, such as oil and water.
Oil seals in the motor, including the engine and other critical components, are essential for maintaining the integrity and efficiency of the vehicle. These seals are designed to contain lubricating oil and prevent leaks, contributing to the smooth operation and longevity of the motor. Proper maintenance and replacement of oil seals in the motor are crucial for the reliability and performance of the vehicle's systems.
VMQ, also known as silicone, is also used for oil seals, but this is less common because the mechanical strength of VMQ is low and this material has poor wear-resistance This makes it less suitable for dynamic applications, but it can withstand fairly low and high temperatures from -60 °C to 200 °C. Many types of VMQ are also suitable for contact with pharmaceutical and food products, so VMQ is an option worth considering. VMQ oil seals are usually available on request.
