A gasket is a thin, deformable material, designed to prevent leaking fluids in industrial and commercial structures by filling in the space between two adjacent surfaces.

Thread sealant is used to fill the voids in threaded connections, preventing leakage caused by factors like temperature fluctuations, vibrations, and pressure changes.

Common sealing materials include rubber, silicone, cork, felt, paper, and other synthetic and natural materials, each with unique properties suited for specific applications.

Locking washers are used to keep fasteners tight and in place, especially under conditions of high vibration, shock, or repeated use, which could otherwise loosen the fastener.
