- In mechanical seals, the lubricant doesn’t get washed out. Therefore, bearing contamination gets avoided in normal operational conditions.

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.
- 1. Check for signs of wear or damage Regularly inspect the seal for any signs of wear, cracks, or tears. If you notice any issues, replace the seal immediately.
1. Criteria for selecting oil seals
What are Oil Seals, and How Do They Work?
Silicone
Wide temperature range
Commonly used in low temperature applications
Very prone to mechanical damage during fitting
Another important factor to consider when choosing spark plugs for your MK7 GTI is the electrode material. The electrode material can vary between spark plugs and can have an impact on the performance of your engine. Copper, platinum, and iridium are common electrode materials used in spark plugs. Iridium spark plugs are often preferred for performance cars like the MK7 GTI due to their durability and ability to maintain a stable spark.
