Based in Dongguan, Guangdong—China’s leading hub for industrial rubber component manufacturing—HS specializes in heavy-duty custom-sized silicone sealing rings, engineered as high-pressure fluid sealing solutions for industrial pumps, valves, compressors, and industrial machinery applications. Our EE-917-C5 silicone rubber gasket seals (also referred to as silicone rubber seals) are precision-crafted via moulding processing to meet the stringent performance standards of heavy-industry equipment, combining high-temperature resistance, material durability, and full customization to deliver reliable machinery accessory solutions for industrial manufacturers worldwide. Whether you require standard silicone rubber seals for industrial machinery or bespoke custom-sized sealing rings for high-pressure compressors, our factory-direct capabilities ensure consistent quality, on-time delivery, and cost-effective solutions tailored to your industrial fluid sealing needs.
Core Features of Our Silicone Sealing Rings Our silicone sealing rings and silicone rubber gasket seals stand out for their heavy-duty durability, high-pressure resistance, and high-temperature performance—key traits that make them ideal for industrial pumps, valves, compressors, and industrial machinery accessories.First, the material quality of our silicone sealing rings is unmatched. We utilize premium industrial-grade silicone rubber (supplemented with EPDM, NBR, and NR options) that delivers exceptional high-pressure resistance (up to 500 PSI) and high-temperature tolerance (withstanding up to 250°C), ensuring silicone rubber seals maintain structural integrity and leak-proof performance in the extreme conditions of industrial fluid systems. This formulation also resists chemical degradation from industrial fluids (oils, solvents, corrosive liquids), extending the service life of sealing components in harsh industrial environments.Second, custom-sized precision defines our silicone sealing rings. Our moulding processing achieves a tolerance of ±0.05mm, ensuring custom-sized and custom-shaped silicone rubber gasket seals create airtight, high-pressure seals for pump housings, valve seats, and compressor chambers—eliminating fluid leaks that compromise equipment efficiency and safety. We offer custom colors per customer’s request and customized logo printing, aligning silicone sealing rings with industrial brand identity without compromising functionality.Third, rugged durability is embedded in every silicone sealing ring we produce. The robust silicone composition resists wear, abrasion from fluid particles, and mechanical fatigue from repeated valve/pump actuation—reducing maintenance downtime and replacement costs for industrial equipment operators.
Competitive Advantages of Our Silicone Sealing Rings Choosing our silicone sealing rings and silicone rubber gasket seals means partnering with a manufacturer with 20+ years of industrial rubber processing expertise, prioritizing performance, customization, and customer-centric service for heavy-industry applications. High-Pressure Compliance & Rigorous Quality Control Every silicone sealing ring undergoes 100% quality inspection before shipment, including high-pressure resistance testing, high-temperature validation, leak-proof performance checks, and dimensional verification—ensuring zero defects and adherence to global industrial equipment standards. Our strict quality control processes guarantee silicone rubber gasket seals meet the durability and sealing benchmarks required for industrial pumps, valves, compressors, and machinery. Custom-Sized Flexibility & Scalable Production We offer a MOQ of 500 pieces for silicone sealing rings, making our solutions accessible to small and medium-sized industrial equipment manufacturers, while our 10,000-square-meter production facility and 2000+ existing molds enable scalable production to meet bulk orders for major industrial machinery brands. Custom sizes, shapes, and material blends (silicone/EPDM/NBR/NR) for silicone rubber seals are available to fit any industrial pump, valve, or compressor component. Cost-Effective Factory-Direct Pricing As a direct manufacturer, we eliminate middleman markups, offering competitive pricing on heavy-duty silicone sealing rings without compromising high-pressure or high-temperature performance. Our one-stop procurement service streamlines design, prototyping, and production, reducing lead times and supply chain costs for your industrial machinery component orders. Technical Expertise & 24/7 Support Our team of industrial rubber engineering specialists provides 7×24 online support for silicone sealing ring inquiries, offering guidance on material selection and seal design optimization for high-pressure industrial fluid systems. We leverage deep heavy-industry knowledge to solve complex sealing challenges, ensuring silicone rubber gasket seals deliver optimal performance in pumps, valves, and compressors.
Applications of Our Silicone Sealing Rings Our versatile silicone sealing rings and silicone rubber gasket seals serve critical sealing roles in heavy-industry settings, thanks to their high-pressure resistance, high-temperature tolerance, and heavy-duty design:
Industrial Pumps: Custom-sized silicone sealing rings seal centrifugal pump impeller housings and positive displacement pump chambers—their high-pressure resistance prevents fluid leaks, and chemical resistance withstands abrasive industrial fluids like hydraulic oil and coolant. Industrial Valves: Silicone rubber gasket seals fit gate, ball, and check valve seats—their durable composition resists wear from valve actuation, and high-temperature performance withstands the heat of industrial process fluids. Air Compressors: Heavy-duty silicone sealing rings seal compressor cylinders and piston heads—their high-pressure resistance (up to 500 PSI) maintains airtight compression, and heat resistance dissipates thermal stress from compressed air systems. Hydraulic Systems: NBR-blended silicone rubber seals act as gaskets for hydraulic valve manifolds and pump outlets—their oil resistance and high-pressure performance optimize hydraulic system efficiency in manufacturing and construction machinery. Chemical Processing Pumps/Valves: Silicone sealing rings seal chemical transfer pumps and control valves—their chemical resistance prevents leaks of corrosive fluids, and custom sizing fits specialized chemical processing equipment designs.
At our Dongguan manufacturing facility, we leverage a team of over 100 skilled professionals and state-of-the-art moulding processing equipment to produce silicone sealing rings that exceed industrial standards. Our commitment to quality is backed by ISO 9001 and ISO 14001 certifications, validating the reliability and sustainability of our silicone rubber gasket seals for international heavy-industry markets. We back all silicone sealing rings with a 3-year warranty: if unused silicone rubber gasket seals develop quality issues within this period, we offer free returns and replacements. Whether you need heavy-duty custom-sized sealing rings for industrial compressors or high-pressure seals for chemical processing pumps, we deliver silicone rubber gasket seals that combine performance, durability, and value—engineered for industry, built to seal.
