1. Washer
is made of paper, rubber sheet, or copper, in order to strengthen the sealing material, arranged to prevent fluid leakage between the seal member sealing surface between the two stationary plane .
Definitions
gasket (Gasket) is a mechanical seal between the two objects, generally between two objects under pressure to prevent corrosion, and the tube Road expansion and contraction naturally leaks. Since the machined surface can not be perfect, using shims to fill irregularities. The shims are typically made of sheet material, such as a pad of paper, rubber, silicone rubber, metal, cork, felt, neoprene, nitrile rubber, glass fibers, or plastic polymers (such as polytetrafluoroethylene). Gasket particular application may contain asbestos.
spacer (Washer) is a thin plate flaw (usually round) (usually in the middle) is typically threaded fastener for load distribution. Other uses are as a spacer, a spring (Belleville washer, wave washer), wear pad apparatus, display a pre-locking device. Also used in the rubber gasket faucet (valve) to cut off the flow of liquid or gas. Rubber or silicone gasket may also be used to reduce vibration of the fan. The outer diameter of the gasket is typically about twice the inner diameter.

spacer
Semi semimetallic gasket Metal gasket with metallic and non-metallic material, such as spiral wound gasket, a metal-coated gasket.
a spiral wound gasket spiral wound gasket by the metal V-shaped or W-shaped cross section with a non-metallic clamp band, the spirally wound gasket.
1) disposed in inner ring inner metal ring of the inner spiral wound gaskets.
2) an outer ring outer ring provided on the metal ring outer ring spiral wound gasket.
B clad metal
metal gasket steel metallic gasket, made of metal such as aluminum, copper, nickel, monel, or the like gasket.
refers to a spiral wound gasket with a metal (typically steel belt v) and the non-metallic belt wound into a ring gasket, metal and non-metallic belt wound alternately with, because it has good flexibility, wide flange seal structure for the petrochemical, chemical, electric power and other industries, depending on the particular site, can be added in the steel ring gasket located or inner or outer reinforcing.
