Bai protect parts and screws.
A gasket is a mechanical seal between two objects, usually used to
prevent pressure, corrosion, and natural pipeline expansion and
contraction leakage between the two objects.Since machined surfaces
cannot be perfect, irregularities can be filled with gaskets.
Gaskets are usually made of sheet materials such as pad, rubber,
silicone rubber, metal, cork, felt, neoprene, nitrile rubber, glass
fiber, or plastic polymers (such as Teflon).Gaskets for specific
applications may contain asbestos.
