Thomas A. Caserta has manufactured rubber washers for many diverse and demanding industries for over 60 years. A rubber washer is a small flat rubber ring used on fasteners and in mechanical devices. Rubber washers are used to seal fluids, prevent leaks, dampen vibration and protect surfaces.

There are many performance specifications that are important for rubber washers. Many different rubber materials can be used in the production of rubber washers to achieve the desired performance. Some of the common materials used are EPDM, Neoprene, Nitrile, SBR, Silicone, and Viton. Different materials are better suited to different applications depending on factors such as temperature resistance, fluid resistance, chemical resistance, ozone resistance, and abrasion resistance. Thus, it is important to choose the correct material for rubber washers to suit your application. Our engineers are always available for any technical assistance you may require.

We manufacture rubber washers to any size and material specification. We also custom manufacture rubber washers with special nibs on the I.D. (inside diameter) designed for automated screw assembly equipment.

Thomas A. Caserta, Inc. utilizes several different methods to consistently produce the highest quality rubber washers for your application depending on the size and tolerance required. Our methods include high speed on-demand cut rubber washers, lathe cut rubber washers, guillotine cut rubber washers, die cut rubber washers, water jet cut rubber washers, and hand cut rubber washers.
