Assembling the oil seal

Seals, including oil seals, have undergone a great development in recent years and are totally unlike the original product. PTFE has taken over the oil seals market for modern engines mainly because traditional oil seals started causing more and more problems. Such as evaporation of chemical plasticisers from the elastomeric material, which eventually caused engine oil leakage. Now, the focus is more on durability and frequency of servicing.

There is a British Standard laid down for the control of synthetic rubbers. BS 3574 (1989) helps to determine shelf life – for instance, Nitrile (NBR) and Polyacrylic (ACM) are Group ‘B’ rubbers and have a 7-year life, whilst Silicone (VMQ) and Fluoroelastomers (Viton®) are Group ‘C’ rubbers and have a 10-year shelf life. PTFE and Leather do not come into this category but like the others should be kept in the original packing for as long as possible away from direct light, dust, and humidity. Ozone, which can also be produced by battery-driven forklift trucks has a very bad effect on synthetic rubbers. Finally, protect the sealing lip – DO NOT hang the seals on nails, wire etc.

There are different types of spark plugs available, including copper, platinum, and iridium. Each type has its own advantages and disadvantages, so it is important to choose the right spark plug for your vehicle based on its specific needs.

White rubber gasket sheets are widely utilized for their adaptability and sealing properties. These sheets are commonly used in applications where a durable and flexible sealing solution is required. The white rubber material offers resistance to heat, chemicals, and weathering, making it suitable for diverse industrial and commercial applications. The sheets can be custom-cut to fit specific requirements, providing a versatile and effective sealing solution.

The sealing process involves the interaction between the rotating shaft and the elastomeric material, resulting in a dynamic barrier that prevents fluid leakage and maintains system integrity.

The hydrodynamic ribsa) provided in one direction on the air side face of the lip ensure higher sealing performance. Perfect Seal The hydrodynamic ribsa) provided in two directions on the air side face of the lip ensure higher sealing performance (higher sealing performance in both rotational directions of the shaft).

With our new, strictly controlled and qualified rubber compounds. Our products are designed to meet any industrial requirements for both OEM and maintenance markets. 

The oil seal should be tough enough to withstand the pressure and the vibrations caused by the shaft and bore. Check if the oil seal is strong enough to tolerate the pressure and vibration.
