Viton Oil Seals - A synthetic rubber and fluoropolymer elastomer, Viton is used to make oil seals that provide resistance in both high temperature, up to 250°C and low compression set components. They also offer a high resistance to chemicals and abrasions, so they can be used in elements that regularly interact with petroleum and solvents.
- In the automotive industry, square rubber gaskets are crucial in engine compartments, sealing oil pans, valve covers, and other components. They prevent oil leaks and maintain the optimal functioning of the engine. Similarly, in plumbing, they ensure leak-proof connections between pipes, taps, and fittings, safeguarding against water damage and potential disasters.
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.
The sealing element, also known as the sealing lip, forms the interior of the oil seal. Various materials can make up the lip depending on the application’s specific needs. Below are some commonly used materials:
Start the engine and check for oil leaks.
Type code
All are fitted with a spring to preload the sealing lip. All these types are for non-pressurised or low-pressure applications up to 0.5 bar for diameters of a limited size. For diameter of 500 mm or more, the maximum pressure is 0.1 bar. For higher pressures, special types or PTFE lip seals can be used.
Auto Head Gasket: Importance in Engine Functionality

Some disadvantages of NBR are poor ozone, sunlight and weather resistance as well as limited high temperature and flame resistance. For higher temperature resistance, a much better material to use is Silicone.
Engine oil seals are vital components in the automotive engine system, designed to prevent the leakage of lubricating oil and the ingress of contaminants. These seals play a critical role in maintaining the proper lubrication of the engine components, including the crankshaft, camshaft, and other critical parts. Engine oil seals contribute to the efficiency and longevity of the engine by preventing oil leaks and ensuring optimal performance.
In addition to these standardised types, the following special types are also available:
