Finding the right rubber oil seal for your application
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.
Take extra care with a light alloy block or head. It is vital to avoid scratching the machined surface.

What are Oil Seals and the different types?
First, an elastomer, most often nitrile, is vulcanised to a metal ring. This creates a stiffening effect that includes a specialised metal tension spring directly behind the sealing lip, keeping the oil seal firmly in place against the moving part.
Because the inner diameter of the oil seal must be stretched during assembly, it is necessary for the shaft to possess a ramped edge. The angle at which the ramped taper should be chamfered is 30° a 50°. If a flange or keyway is present on the shaft, it is best to use a bushing. The bore should also have a chamfer of 30° over at least 1 mm on the ramped side. Be sure to round off the edges properly in the process.

When selecting the 75x100x10 oil seal for a specific application, it's essential to consider factors such as the operating temperature, speed, and pressure of the equipment. Different materials and designs are available for oil seals, each with its own set of characteristics and advantages. Consulting with a knowledgeable supplier or manufacturer can help you choose the right oil seal for your needs.
The valve cover gasket plays a critical role in maintaining the integrity of the engine by preventing oil leaks and maintaining proper lubrication. It ensures that the engine remains free from oil leaks, contributing to its overall efficiency and reliability. A high-quality valve cover gasket is essential for preserving the proper functioning of the engine and protecting it from potential damage due to oil leakage.
