O.D. (outside diameter) surface The O.D. surface affixes the oil seal to the housing and prevents leakage , through the fitting area, of substances to be sealed, while excluding contaminants.

Just like pressure. The temperature capability of the oil seal shouldn’t be lesser than the temperature of the application. This is because any significant increase or even decrease in the temperature will affect the functionality of the oil seal. PTFE seals have the highest temperature capability, making them useful for applications that demand harsh weather and elements.

The spring shown in the figure is known as a garter spring, and it maintains tension on the sealing lip of the seal. Garter springs are closed coil springs used in the form of a ring, the ends of which are connected together as shown in Figure 2.10.

 Oil seals go by many names, such as shaft seals, dirt seals, grease seals, lip seals, and many other variations of these. They are essentially simple devices used in rotary shaft equipment to prevent lubricant from escaping and for excluding contaminants such as dust, dirt and water. An oil seal’s most important function, however, is that it protects every type of ball, sleeve and roller bearing in the rotating shafts. The seals also prevent the integration of two different fluids that shouldn’t mix, such as oil and water.

Maintenance and Replacement of Oil Seals:

The car engine head gasket is a vital component that ensures the proper sealing of the combustion chamber, allowing for efficient fuel combustion and the containment of high-pressure gases. This gasket is subjected to extreme temperatures and pressures, making it essential to select high-quality, durable materials that can withstand these conditions. The car engine head gasket is crucial for maintaining the integrity and performance of the engine, contributing to the overall reliability and longevity of the vehicle.

The block is unlikely to distort except after severe overheating, but check anyway using a steel ruler or similar high-quality straight-edge.

The 40mm rubber gasket is a versatile sealing solution that is commonly used in plumbing systems, automotive engines, hydraulic systems, and other machinery where a tight seal is required. Made from high-quality rubber materials, these gaskets are designed to withstand high temperatures, pressure, and chemicals, making them suitable for a wide range of applications.

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.

Our suppliers try to provide the best quality oil seals and products are in some cases optimised to improve performance and fitment. Corteco is one of these brands, whose case studies we have listed for you.
