When the oil seal material and the chemical are not compatible, there will be a chemical attack, which increases at high temperatures. The only way to remedy this is to select the right material for your application. If you’ll be dealing with harsh chemicals, choose oil seals that are made with reliable materials for their compatibility.
• Super helix seal (seal with one-way two-step screw)

PTFE, which is used in the well-known brand Teflon®, is less commonly used, but it is the preferred material for specific rotating seals in the chemical, food and pharmaceutical industries. This material is notable for having a very low frictional resistance and the best chemical resistance. It can also withstand a very wide range of temperatures in these types of seals; -80 ˚C to 200 ˚C. The shafts on which oil seals with PTFE lips are used require a harder and finer finish. Something like an axle sleeve can also be used to meet this requirement.

oil seal types. Labyrinth seals are designed to provide a barrier to the leakage of oil by creating a tortuous path for the oil to flow through. V-ring seals, on the other hand, are designed to provide a more dynamic sealing solution by conforming to the shaft, thus preventing oil leakage.

Selecting Quality Car Engine Head Gaskets and Automotive Rubber Gaskets
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.
