One of the key advantages of the 40mm rubber gasket is its flexibility and resilience, allowing it to conform to irregular surfaces and maintain a tight seal under varying conditions
. This property makes it an ideal choice for sealing joints, flanges, and connections in industrial equipment and machinery.40mm rubber gasket

Sealing principle: Since there is an oil film controlled by the oil seal edge between the oil seal and the shaft, the oil film has fluid lubrication characteristics.
Oil seals, also known as shaft seals, are radial lip type seals which are primarily used for retaining lubricants in equipment having rotating, reciprocating or oscillating shafts. The rotating shaft application is most common.
