Introduction to Rubber Seals
Rubber seals are essential components used in a wide range of industries to prevent the leakage of fluids, gases, and dust. They are made from various types of rubber materials, such as natural rubber, synthetic rubber (e.g., nitrile rubber, silicone rubber, EPDM rubber), and fluorocarbon rubber, each with its own unique properties and applications. Rubber seals play a crucial role in ensuring the proper functioning and reliability of mechanical equipment, automotive engines, aerospace systems, and many other products. They can be found in different forms, including O - rings, gaskets, oil seals, and custom - molded seals.
