Introduction to Rubber O - Rings
Rubber O - rings are one of the most common and essential sealing components in various industries. They are circular elastomeric seals with a cross - section in the shape of an "O". These rings are designed to prevent the leakage of fluids (liquids or gases) between two mating surfaces. Their simple yet highly effective design allows them to be used in a wide range of applications, from automotive engines and hydraulic systems to household appliances and aerospace equipment.
The materials used to make rubber O - rings vary, including nitrile rubber (NBR), which offers good resistance to oil and fuel; fluorocarbon rubber (FKM), known for its excellent chemical and high - temperature resistance; silicone rubber, which has good flexibility and low - temperature performance; and EPDM rubber, which is resistant to weathering and ozone.
