2. How to select the right oil seal -

Polyacrylate Oil Seals - Mostly selected for automotive and transmission uses, polyacrylate seals are able to withstand fuel, oil, ozone, sunlight and weather when used. With cars exposed to all these different fluids and elements, they are the perfect choice. However, they should not be used in low temperatures, as their flexibility weakens when cold.

The raw rubber material is first compounded with specific additives to enhance its properties, then shaped into the desired form The raw rubber material is first compounded with specific additives to enhance its properties, then shaped into the desired form

thin rubber gasket. Post-production, quality control checks are rigorous to ensure each gasket meets stringent standards for durability and performance.

The metal used in the outer case of oil seals is usually made of carbon steel. Upon request, and depending on quantities, a different type of steel (such as stainless steel) can be used.

Material: There are several material options. Nitrile (Blank), Viton (V), Silicone (S), EPDM (E), Carboxylated Nitrile (X), HNBR (H), Polyacrylate (P), and Teflon (T).
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.)
The basic principle of sealing is straightforward – the flexible lip is held against the rotating part (usually the shaft) whilst the casing (or O.D.) is pressed into the housing or bore and holds the seal in place. The sealing lip needs some form of lubrication to avoid overheating and is usually energized by means of a garter spring.
Fitting an oil seal
The sealing process involves the interaction between the rotating shaft and the elastomeric material, resulting in a dynamic barrier that prevents fluid leakage and maintains system integrity.
Oil seals normally consist of three basic components: the sealing element, the metal case, and garter spring.
Valve Cover Gasket and Head Gasket: Critical Sealing Components
The mechanical seal is used in a pump, mixer and other mechanical engineering scenarios to contain the fluid within a vessel where a shaft rotates through a stationary (or rotating) housing.
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.

There are a few options to remedy this situation:
Installation Techniques
In addition to their resilience, neoprene foam gaskets also provide excellent sealing properties. The foam material is compressible, allowing the gaskets to conform to irregular surfaces and create a tight seal. This sealing capability makes neoprene foam gaskets an effective solution for preventing leaks and ensuring the integrity of equipment and machinery.
