Once the engine is securely held, lower and remove the jack.
- In addition to their chemical resistance, cork rubber gaskets also have excellent thermal stability
- In conclusion, the rubber gasket seal, though often overlooked, is a vital component in numerous industrial applications. Its ability to provide reliable seals in harsh conditions, resist degradation, and maintain functionality over time makes it an indispensable tool in the engineer's arsenal. As technology advances and new materials emerge, the role of rubber gasket seals will continue to evolve, adapting to meet the ever-changing demands of modern industry.

Seals are classified by O.D. wall material, lip type, and whether they have a spring or not.
Major oil seals are specified in ISO 6194-1 and JIS B 2402-1.
Table 2 shows the common types of oil seals, while Table 3 shows the features of each type of oil seal.
Table 4 lists the JTEKT oil seal type codes and corresponding ISO and JIS standards.

rotary shaft oil seal. It is important to choose a high-quality seal that is compatible with the requirements of the system to ensure optimal performance and longevity.
PTFE oil seals


Loosen the securing-clamp bolt at the base of the distributor, then carefully withdraw the distributor.

As an example, this oil seal has a part number that corresponds to a Shaft Size of 3”, a Bore Size of 4”, a Width Size of 0.625”, a Style of TB2, and is made of Viton material. Conversely, the same size oil seal in Metric has a Shaft Size of 76.20 mm, a Bore Size of 101.60 mm, and a Width Size of 15.88 mm.
The interaction of the integrated seals with the shaft follows the dynamics of the PTFE seals. Often an additional dust seal (rubber lip or felt strip) provides an effective barrier against contaminating particles.
