Bonded washers, (also known as dowty bonded seals), are sealing washers that consist of a metal washer and a rubber sealing element bonded together. These types of washers are commonly used in hydraulic systems and other applications where a strong and reliable seal is required to prevent leaks.

The metal outer ring provides stability and strength, while the rubber inner ring serves as the sealing element. Commonly used in hydraulic systems, pipe connections, and fittings where a reliable and durable seal is essential. Suitable for use in various industries, including automotive, manufacturing, and construction. Installed by placing the washer between two mating surfaces. When the connection is tightened, the rubber seal is compressed, creating a reliable and tight seal. Available in assorted sizes and specifications to accommodate different applications and connection types.
