Based in Dongguan, Guangdong—China’s premier hub for industrial rubber component manufacturing—HS specializes in custom industrial silicone rubber seals, engineered as heat-resistant, RoHS-compliant O-rings and machinery accessories for industrial machinery and automotive engines. Our EE-916-C1 silicone rubber seal is precision-crafted via moulding processing to meet the stringent performance standards of global industrial and automotive sectors, combining material versatility, full customization, and high-temperature resistance to deliver reliable sealing solutions for manufacturers worldwide. Whether you require standard silicone rubber seals for industrial machinery or bespoke custom-shaped O-rings for automotive engines, our factory-direct capabilities ensure consistent quality, on-time delivery, and cost-effective solutions tailored to your industrial sealing needs.
Core Features of Our Silicone Rubber Seals Our silicone rubber seals stand out for their industrial-grade heat resistance, RoHS compliance, and material flexibility—key traits that make them ideal for machinery accessories, industrial machinery, and automotive engine applications.First, the material quality of our silicone rubber seals is unmatched. We utilize premium silicone rubber (supplemented with EPDM, NBR, and NR options) that delivers exceptional high-temperature resistance (withstanding temperatures up to 250°C), ensuring silicone rubber seals maintain structural integrity and sealing performance in the extreme heat of automotive engines and industrial machinery. This formulation is fully RoHS-compliant, free of restricted hazardous substances, making silicone rubber seals suitable for global industrial and automotive markets.Second, precision engineering defines our silicone rubber seals. Our moulding processing achieves a tolerance of ±0.05mm, ensuring custom-sized and custom-shaped silicone rubber seals create airtight, leak-proof seals for machinery components and automotive engine parts—eliminating performance issues caused by ill-fitting seals. We offer custom colors per customer’s request and customized logo printing, aligning silicone rubber seals with brand identity without compromising functionality.Third, durability is embedded in every silicone rubber seal we produce. The robust material composition resists wear, chemical degradation, and mechanical stress, extending the service life of machinery accessories and reducing maintenance costs for industrial and automotive equipment operators.
