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.
- White rubber gaskets are predominantly made from synthetic polymers or natural rubber, offering an excellent balance between cost-effectiveness and durability. Their pliability allows them to conform to irregular surfaces, creating a tight seal that prevents liquid or gaseous substances from escaping or entering where they're not wanted. This property is critical in pipeline systems transporting water, gas, or chemicals, where leaks could lead to environmental damage or safety concerns.
Loosen the securing-clamp bolt at the base of the distributor, then carefully withdraw the distributor.
Regular inspection and maintenance of engine oil seals, power steering oil seals, and motor 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 these seals. When replacement is necessary, selecting the correct seal type and ensuring proper installation are critical to maintaining the integrity and performance of the vehicle's systems.
