O-Rings
Washers can be specified in ANSI nominal sizes or ANSI metric sizes. Important size dimensions to consider when specifying washers include Inside Diameter, Outside Diameter, Thickness or working Height, and rated or working load. Materials of construction include Aflas, FKM or VITON, SILICON, EPDM, NBR, NEOPRENE, PTFE, PU, SBR & NATURAL. The hardness rating on a Shore A scale for Washers can be 30 ~ 95 Durometer. Exact specifications should be clarified by our engineers, as the chemical and physical properties of Washers can differ based on manufacturing technique.
Washers
Rubber washers are small, circular or flat components made from rubber, designed to create a secure, leak-proof seal for fluids, gases, and air. They are widely used across various industries, including plumbing, automotive, electronics, and construction.
