What is the function of the gasket
1. The main function of the gasket is to increase the contact area, reduce the pressure, prevent loosening, and protect parts and screws.
2. The gasket is a mechanical seal between two objects, usually used to prevent pressure, corrosion, and natural expansion and contraction of pipelines from leaking between two objects. Since machined surfaces can never be perfect, irregularities can be filled with shims. Gaskets are usually made of sheet-like materials such as paper pads, rubber, silicone rubber, metal, cork, felt, neoprene, nitrile rubber, fiberglass, or plastic polymers such as Teflon. Gaskets for certain applications may contain asbestos.
