product introduction
Our rubber O-rings feature a classic circular cross-section design, which relies on appropriate compression deformation to fill the gap between sealing surfaces, effectively blocking the leakage of media such as gas, liquid and oil. Whether in high-pressure hydraulic systems, high-temperature equipment or corrosive chemical environments, our O-rings can maintain stable sealing performance, with strong adaptability and long service life, perfectly meeting the strict requirements of industrial production.


material selection & application scenarios
We offer a full range of rubber materials to match different working conditions, ensuring optimal sealing effect in specific scenarios:
1. EPDM O-Rings: Strong resistance to weather, ozone, water and steam, no easy aging. Applied in outdoor equipment, water supply pipelines, heating systems, temperature range -50°C ~ 150°C.
2. Nitrile (NBR) O-Rings: The most cost-effective option with excellent oil, fuel and lubricant resistance. It is widely used in hydraulic systems, automotive fuel pipelines and mechanical lubrication parts, applicable temperature range -40°C ~ 120°C.
3. Silicone (VMQ) O-Rings: Food-grade, medical-grade available, with outstanding high and low temperature resistance, non-toxic and tasteless. Suitable for food & beverage processing equipment, medical instruments, household appliances, temperature tolerance from -60°C to 230°C.
4. Fluorocarbon (FKM/Viton) O-Rings: Premium material with superior chemical resistance, high temperature resistance and aging resistance. Ideal for chemical processing, aerospace equipment and high-heat corrosive environments, working temperature -20°C ~ 200°C.
5. Natural Rubber (NR) O-Rings: Excellent elasticity and wear resistance, cost-efficient for general low-pressure sealing scenarios like ordinary mechanical equipment, applicable temperature -50°C ~ 80°C.
core performance advantages
1. Precision Sealing: Uniform cross-section, smooth surface without burrs, precise dimensional tolerance (up to ±0.05mm for precision grade), ensuring tight fit and zero leakage.
2. Stable Performance: Strong elasticity, excellent wear resistance, aging resistance and media compatibility, reducing frequent replacement and maintenance costs.
3. Wide Adaptability: Cover vacuum to 300MPa sealing pressure, adapt to various media including oil, water, gas, chemical solvents, suitable for multi-industry scenarios.
4. Strict Quality Control: Each batch of O-rings undergoes dimensional inspection, hardness testing and pressure sealing test, fully compliant with RoHS, REACH and relevant industrial quality standards.
5. Efficient Supply: Standard sizes are in stock, supporting 24-hour quick quotation and 3-5 working days fast delivery; custom orders provide sample confirmation before mass production to ensure product consistency.
