Rubber Sealing Washers

Rubber Sealing Washers are designed to create a fluid-tight or air-tight seal between the fastener head and the mounting surface. Featuring bonded rubber, plastic, or soft metal interfaces, these washers prevent leaks and protect against moisture, dust, and contaminants. Ideal for plumbing, hydraulic systems, and outdoor enclosures, our sealing washers offer superior chemical resistance and durability. They provide a dependable solution for maintaining pressure integrity and preventing corrosion in critical assembly points.
