Customized O-ring Sealing Silicone Rubber High-temperature Heat-resistant

Our Customized Silicone Rubber O-rings are core sealing components widely used in automotive, electronics, medical, food & beverage, aerospace, and industrial machinery fields. Made of high-purity silicone rubber, these O-rings possess excellent flexibility, resilience, and chemical stability, effectively preventing leakage of liquids, gases, and dust in harsh environments. Whether in high-temperature equipment, humid working conditions, or complex mechanical systems, our O-rings maintain stable sealing performance, ensuring the safe and efficient operation of your equipment.

• Superior High-temperature & Heat Resistance: Withstand a wide temperature range of -60°C to 200°C, and can tolerate short-term high temperatures up to 250°C. It maintains excellent elasticity and sealing performance even in high-temperature working environments such as engine compartments and industrial furnaces, without deformation or aging.

• Excellent Waterproof & Sealing Performance: The dense molecular structure of silicone rubber and precise molding process ensure perfect airtightness and watertightness, effectively blocking the intrusion of water, moisture, and other media, suitable for both static and dynamic sealing scenarios.
• Full Customization Service: We support comprehensive customization according to your drawings, samples, or specific requirements, including size (inner diameter: 1mm-200mm, cross-section: 0.5mm-10mm), hardness (Shore A 30-80), color (standard black, red, transparent, or customized Pantone colors), and surface finish (solid, translucent, matte). OEM/ODM services are available to meet your brand and application needs.
• High Quality & Durability: Adopt high-purity silicone rubber raw materials that comply with FDA, RoHS, and REACH standards, non-toxic, odorless, and non-corrosive. Through strict mixing, vulcanization, trimming, and quality inspection processes, the O-rings have excellent tensile strength, elongation at break, and compression set resistance, with a long service life and stable performance.
• Strong Chemical Resistance: It has excellent resistance to salt solutions, ozone, UV, hot air, and ethylene glycol, and can be used in various harsh chemical environments. It is also compatible with dilute acids and ethanol (within a certain temperature range), making it suitable for diverse industrial scenarios.

Our Customized Silicone Rubber O-rings are widely used in various industries due to their excellent performance, including but not limited to:

• Automotive Industry: Engine systems, transmissions, battery packs, headlight packaging, air conditioning compressors, and fuel system sealing, suitable for both fuel-powered and new energy vehicles.
• Electronics & Electrical Industry: Sealing of electronic components, sensors, connectors, 5G base stations, and photovoltaic modules, providing dustproof and waterproof protection for equipment.
• Medical & Pharmaceutical Industry: Sealing of medical devices, infusion pumps, dialysis machines, and pharmaceutical equipment, with biocompatibility and resistance to high-temperature sterilization.
• Food & Beverage Industry: Sealing of food processing equipment, pumps, valves, fermenters, and food packaging, complying with FDA and LFGB standards to ensure food safety.
• Aerospace & Industrial Machinery: Sealing of aerospace equipment, industrial pumps, compressors, hydraulic systems, and chemical equipment, adapting to extreme working environments.
