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.

Materials Used

Materials Used

N/A
These are the most common material but we are not limited to them:

Ethylene Propylene Diene Monomer (EPDM) - Excellent weatherability, good high and low temperature resistance, low gas permeability. Resistant to ozone, steam, water, alcohols, brake fluids. Poor resistance to petroleum oils, diester lubricants. Temperature range: -60°F to 280°F.

Neoprene - Good general purpose elastomer, with moderate oil, ozone and water resistance. Resistant to freons, high aniline points oils, mild acids. Not recommended for phosphate esters, ketones, brake fluids. Temperature range: -65°F to 260°F.

Nitrile - Excellent resistance to petroleum products, excellent compression set; resistant to oil, water, silicone greases and oils. Not recommended for halogenated hydrocarbons, ketones, ozone and sunlight. Temperature Range: -65°F to 275°F.

Styrene-Butadiene Rubber (SBR) - General purpose elastomer, good adhesion to various substrates, good abrasion resistance, good resiliince. Resistant to brake fluids, alcohols, water. Not recommended for solvents, oil/gas, sunlight. Temperature range: -65°F to 225°F.

Silicone - Best overall temperature range of elastomers currently available. Excellent resistance to dry heat, as well as, resistance to low temperature, brake fluids, high aniline point oils. Not recommended for some dynamic applications due to poor tensile strength and tear. Poor in petroleum oils and ketones. Temperature range: -150° to 500°F.

Viton® - Outstanding resistance to the effects of heat, chemicals, and solvents. Viton® has good tensile, resistance and low compression set. Limitations include poor low-temperature properties, limited hot-water resistance and shrinkage. Temperature range: -50° to 600°F.
