Before fitting the oil seal, it is essential to check that the oil seal, shaft and bore are clean and undamaged. The surfaces the oil seal will come into contact with must be free of sharp points or burrs. The sealing lip is fragile, so even minimal damage can cause a leak. It is also important that the shaft and bore are correctly finished.

In conclusion, the spark plug valve cover gasket, despite its seemingly minor status, is a vital element in maintaining your vehicle's health and performance. It's a small part with a significant responsibility, ensuring that your engine runs smoothly, efficiently, and without unnecessary interruptions. Remember, prevention is always better than cure, so keep an eye on this often-overlooked component for a well-functioning and reliable vehicle. An oil tank gasket is a crucial component in the safe and efficient operation of an oil tank. This small but important piece of equipment helps to prevent leaks and ensure that the tank remains secure and airtight.• Machining of lip surface (stable oil drip under pressure)
O-rings, which are also referred to as oil seal rings or oil ring seals, are designed to join two parts and ensure that no air, moisture, or gas is allowed to pass through. They are usually inserted into a groove and manufactured to resist pressure. The resistance is what stops foreign elements from entering or leaving the joining.
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.
