Seal washers are used as sealing components in mechanical equipment and pipelines wherever fluids are present. They are made from metal or non-metallic sheet materials, cut, pressed, or trimmed, and serve as密封 connections between pipeline joints and components within machinery. They are categorized into metal and non-metal seal washers. Metal types include copper, stainless steel, iron, and aluminum washers. Non-metallic types include asbestos, non-asbestos, paper, and rubber washers.
