In this kind of seal, wider tolerances are possible between the OD of the seal and the seal housing. Irregularities of the housing surface can be taken up by the resilient rubber layer on the outside of the seal. However, the rubber covered seal can be blown out under high pressure in a reciprocating application whereas, with a metal case, there is no such danger.



What should you take into account when selecting an oil seal? Different types of oil seals and various types of materials are available, each designed for specific uses. It is also important to select the right size of oil seal for the best results. For this reason, selecting the right oil seal requires adequate understanding of the application in which it will be used.
Factors in Oil Seal Selection
The design of high-pressure oil seals is also critical to their performance. The seals must be able to maintain a tight fit between the moving parts, while also allowing for some flexibility to accommodate minor variations in the shaft or housing. This balance between rigidity and flexibility is essential for ensuring a reliable seal under high pressure conditions.
