What is a mechanical seal made of?

A mechanical seal typically consists of several materials that work together to prevent leakage in rotating equipment. The core components include a seal face, often made from hard materials like ceramic or tungsten carbide, and a counterface, which might be composed of carbon or a similar material. The faces are pressed together to create a tight seal. Elastomers, such as Viton or nitrile rubber, are used for the secondary sealing elements to ensure flexibility and adaptability. Springs or other mechanical elements are incorporated to maintain the required pressure on the seal faces. Each component is selected for its ability to withstand the specific operating conditions, including temperature, pressure, and chemical exposure.
