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.

THE DIFFERENT SIZES OF OIL SEALS

5. TYPES OF FLUID: Numerous oil seals can interact with oils, fuels, grease, water and more. However, know exactly what type of fluid the rotary shaft seal will be in contact with will ensure the longevity of the seal and the machinery.

Another method to test your spark plug wires is to use a spark tester. This device produces a small spark when connected to the spark plug wires, allowing you to visually inspect them for any signs of wear or damage. To use a spark tester, follow these steps

The 5.9% Magnum valve cover gasket is a crucial component in the engine that is often overlooked but plays a significant role in maintaining the performance and efficiency of the vehicle. This gasket seals the valve cover to the cylinder head, preventing oil leaks and keeping the engine running smoothly.

Overall, oil seals play a crucial role in ensuring the smooth operation of machinery and equipment in various industries. By preventing oil leaks, reducing maintenance costs, and improving efficiency, oil seals are an essential component in the effective functioning of machinery.
