Silicone o rings

Kinshing Silicone is a trusted worldwide leader in sealing solutions, offering a comprehensive range of silicone seal O-rings. Our O-rings are designed for industrial applications, preventing leaks and maintaining pressure in pumps, compressors, and hydraulic systems. With over 20 years of experience, we manufacture high-quality rubber O-rings, seals, and gaskets using various elastomers.


Silicone O-rings are highly temperature-resistant, UV-resistant, and corrosion-resistant. They withstand exposure to oils, chemicals, solvents, and electrical insulation requirements. FDA-approved for food handling equipment and appliances, silicone O-rings are non-toxic and ideal for various industries, including automotive, aerospace, and medical.

Made from synthetic silicone materials derived from quartz, these O-rings have a temperature resistance range of -60°C to 225°C, with special varieties reaching -100°C to 300°C. They exhibit excellent elasticity, chemical resistance, heat insulation, and electrical insulation properties. While they are flexible at low temperatures, silicone O-rings have low tensile strength, tear strength, and wear resistance. For enhanced protection against erosion, a Teflon sleeve can be used.

Our silicone O-rings are known for their durability, long-lasting performance, and resistance to wear and tear. We offer a wide range of standard sizes, as well as custom configurations tailored to your specific needs. Whether you require custom hardness, colors, or industry certifications, we can provide silicone O-rings, gaskets, and seals that meet your application requirements.

These circular seals are cost-effective, easy to install, versatile, and capable of handling high pressures. Silicone O-rings excel in mechanical equipment applications and are commonly used in aerospace and automotive industries. We supply high-quality, well-customized O-rings made from platinum-cured, peroxide-cured, fluoro silicone, conductive silicone, and other rubber materials for various industries.

Choose Kinshing as your reliable supplier of silicone O-rings, and benefit from our expertise, customization options, and commitment to delivering high-quality sealing solutions for your industrial needs.
