- Rubber, as a material, offers a unique blend of properties that make it ideal for gasket manufacturing. It possesses excellent flexibility, allowing it to conform to irregular surfaces and maintain a tight seal. Moreover, rubber has inherent resistance to chemicals, weathering, and abrasion, which makes it suitable for use in harsh environments. The thickness of the rubber further amplifies these attributes, providing a more robust and long-lasting sealing solution.
- 4. Store the seal properly Storing the seal in a dry, clean environment can help prevent damage and extend its lifespan.
- 2. HVAC Systems These gaskets are widely used in heating, ventilation, and air conditioning (HVAC) systems to ensure a tight seal between ducts, registers, and other components. Their ability to withstand extreme temperatures makes them ideal for use in both residential and commercial HVAC systems.
○ - 8. Test the ignition system Start the engine and check for any signs of misfires or other issues. If everything is functioning correctly, you have successfully installed the Spark Plug 794 055A.


Oil seals have a flexible lip that actually rubs against the rotating shaft or housing to prevent leakage. The spring keeps the lip in contact with the shaft. Bearing isolator oil seals are dynamic seals that incorporate a rotor or rotating member and a stator or stationary member. The rotor actually turns with the shaft. Some oil shafts are bearing isolators with a labyrinth construction. Others incorporate simpler O-rings.
These oil seals are the best for applications involving high temperatures. It’s suitable for temperatures between -4 degrees Fahrenheit and 392 degrees Fahrenheit. Also, it’s highly resistant to acids, dissolvent materials, and other chemicals. Viton (FKM/FPM) oil seals can run at a maximum speed of 38 m/s.

EPDM oil seals are less common. They are used in solvent, hot water and steam applications, EPDM resists low temperatures down to -50 °C and UV radiation well. Some types of EPDM are also suitable for higher temperatures up to +150 °C. EPDM oil seals are usually available upon request.

Beyond the variety of lip designs, oil seals also come in various case designs, each serving a unique role. Here are some of the most common ones:
Leather Oil Seals - Leather Seals, also known as Type L Oil Seals, are most common in components that are subject to dirt and poor lubrication. Since they come pre-lubricated and are able to absorb fluids, leather oil seals are able to provide sealing properties in conditions that synthetic rubber is unable to.
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.
