Introduction to Rubber Rings
Rubber rings, also known as O - rings, are one of the most widely used sealing elements in various industries. They are circular in shape and made of different types of rubber materials such as nitrile rubber (NBR), silicone rubber (VMQ), fluorocarbon rubber (FKM), and ethylene - propylene - diene monomer (EPDM). Rubber rings work by creating a tight seal between two mating surfaces, preventing the leakage of fluids (liquids or gases) and protecting the internal components from external contaminants.
They are used in a vast range of applications, including automotive engines, hydraulic systems, plumbing fixtures, aerospace equipment, and consumer electronics. The performance of rubber rings depends on factors like material properties, hardness, temperature resistance, chemical compatibility, and the design of the sealing system.
