(3) The oil seal with general pressure has poor pressure bearing capacity, and the oil seal will deform when the pressure is too large. In the case of excessive pressure, a pressure-resistant bearing ring or a reinforced pressure-resistant oil seal should be used.

contaminated with moisture or any other particle. But the same oil will only last for a month at 212 degrees Fahrenheit if it’s contaminated with little water. This is why the function of an oil seal is very evident whenever it’s used.
The piston oil seal is located between the piston and the cylinder wall. Its main function is to seal the combustion chamber and prevent oil from leaking into the combustion area. This is essential for maintaining proper lubrication of the piston and preventing damage due to overheating and friction.
Car engine oil seals are essential components that prevent oil leaks and maintain proper lubrication within the engine. They play a crucial role in preserving the integrity and efficiency of the engine, contributing to its overall performance and longevity. High-quality engine oil seals are designed to withstand the demanding conditions of automotive operation, ensuring reliable sealing solutions for critical engine components.
The mating surfaces of the head or block must be perfectly clean, flat and smooth.
