3. The spring on the lip of the oil seal tends to provide support to the lip and prevents the lubricant from leaking outside and also prevents the entry of contaminants from outside.
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.

An overview of the different standard types of oil seals and their main characteristics is shown below.

Clean sediment out of the sump with petrol and a stiff brush . Dry with a lint-free cloth.
Place the ruler or straight-edge on edge diagonally across the head and block and look for gaps showing light anywhere between the ruler and block.
Oil seals close spaces between fixed and moving parts and protect all kinds of ball and roller bearings. They keep rotating shafts and bearings from pollution and corrosive materials, and also prevent lubricants, oils, and liquids from leakage. An oil seal can have a single lip, double lip and even triple lip, so single lip seal is one lip to seal around the shaft, double lip seal is two lips sealing around this, and triple lip seals have three lips to seal.
How are they used?

12 22 5 oil seal. Its ability to resist wear and tear ensures that machinery stays operational for longer periods without the need for frequent maintenance.
Conventional oil seals are the traditional seals, which can be recognised by a spring on the inside. These oil seals are made of a metal housing that contains a rubber seal. This part is often made of elastomer and comes into contact with the surface of the rotating shaft.
