Introduction to O – rings and Seals
O – rings and seals are fundamental components in various industrial and mechanical applications. An O – ring is a doughnut – shaped gasket, typically made of elastomers such as rubber, silicone, or fluorocarbon. Its primary function is to prevent the leakage of fluids (liquids or gases) between two mating surfaces. Seals, on the other hand, are a broader category that includes O – rings as well as other types of gaskets, lip seals, and mechanical seals. They play a crucial role in maintaining the integrity of systems by keeping contaminants out and the necessary fluids or gases inside. From automotive engines and aerospace equipment to household appliances and industrial machinery, O – rings and seals are essential for the proper functioning and reliability of countless devices.
