About Rubber Washer

Offered Rubber Washers have been produced by following advanced compression molding technology. Made of silicon or elastomer material, these rubber items are highly durable. Featured with ergonomic look, such rubber products are popularly used as automobile components. Offered rubber items are also used as essential parts of electronic components to avoid shock and friction. These are offered both in standard and also in customized specifications. These washers have self adhesive seals that enables these to endure the toughest working conditions. Anti skid properties, smooth surface and required density make these ideal for different machines and vehicles. These washers are cost effective.

Excellent Electrical Insulation

Engineered with high dielectric strength, these rubber washers effectively prevent unwanted electrical conductivity. This makes them suitable for electrical and electronic appliances, ensuring safety and performance. Their naturally low thermal conductivity further enhances protection against electrical hazards. Custom material selection is available for projects requiring a specific insulation rating.

Superior Customization Options

Our washers can be tailored by diameter, thickness, material, and resistance features to meet your exact engineering needs. Whether you require additional UV or ozone resistance, or bespoke sizes for unique installations, we provide flexible formulations and manufacturing. Enjoy precision tolerances (0.1 mm) and a variety of rubber types, including neoprene, EPDM, nitrile, and natural rubber.

Durable and Versatile Applications

With a tensile strength of 1020 MPa and excellent compression recovery, these washers achieve high performance in sealing, cushioning, and vibration dampening across plumbing, machinery, and automotive sectors. Their water, oil, and moderate chemical resistance, combined with a temperature range of -20C to +90C, support longevity even in demanding environments.

FAQs of Rubber Washer:

Q: How are rubber washers customized to fit specific size and application requirements?

A: Rubber washers can be customized by diameter (8100 mm), thickness (110 mm), and selected rubber material such as natural rubber, neoprene, EPDM, or nitrile. Custom formulations for UV and ozone resistance are also available, allowing the washers to suit particular environments and installation needs.

Q: What benefits does excellent electrical insulation bring to rubber washers?

A: Excellent electrical insulation ensures that the washers act as non-conductive barriers, preventing electrical current leakage and minimizing the risk of short circuits. This makes them suitable for use in electrical appliances and machinery, improving operational safety and device longevity.

Q: When should you consider using a washer with enhanced ozone or UV resistance?

A: Enhanced ozone or UV resistance is recommended when the washer will be exposed to outdoor or high-ozone environments, such as in exterior electrical equipment or UV-intensive machinery. These custom features improve durability and reduce premature degradation caused by environmental conditions.

Q: What is the manufacturing process for these rubber washers?

A: The washers are produced through precision molding and cutting of rubber compounds tailored to order specifications. The process ensures low levels of ash, volatile matter, and nitrogen content, yielding a smooth surface finish and consistent mechanical properties like compression ratio and elongation.

Q: Where are these rubber washers frequently used?

A: They are commonly used in plumbing systems to prevent leaks, in automotive assemblies for cushioning and noise reduction, and in electrical appliances for sealing and insulating. Their application spans machinery, electrical equipment, and any planar interface where sealing or insulation is critical.

Q: How does the compression recovery property benefit usage in sealing applications?

A: With approximately 30% compression recovery, these washers retain their shape and maintain sealing force after repeated compression cycles, ensuring a tight seal over long-term use and reducing maintenance frequency in dynamic assemblies.
