A square rubber gasket is a vital component in various mechanical applications, providing a seal between two surfaces to prevent leakage or contamination. These gaskets are commonly used in machinery, engines, piping systems, and automotive applications.
Different Types of Oil Seals

In addition to its excellent temperature resistance, it is also resistant to ozone, light, and weather conditions. Silicone can be typically found in the food and medical industry as well as in hydraulics and pneumatics. It is often the preferred material for o-rings, moulded parts and flat seals but is also commonly used for electric insulators due to the material’s translucency and flexibility.

metal oil seal.
Most oil seals consist of some basic elements that configure their structure, such as the sealing element, the metal case, and the spring:
Conventional oil seals
0.1 to 0.32 μmRa and 0.8 to 2.5 μmRz
and the lead angle to no greater than 0.05°. (There is a risk that the lead marks will impede the sealing performance of the oil seal: see Figure 5.)
