Core Product Features
- Premium Dual-Material Performance: Blending EPDM and silicone, the O-ring inherits EPDM’s excellent resistance to water, steam, acids, bases, and ozone, as well as silicone’s outstanding high and low temperature tolerance (-60℃ to +230℃), ensuring stable performance in harsh environments.
- Precision Molded Customization: Fully customized according to your drawings, samples, or specifications. We offer flexible customization of inner diameter, outer diameter, line diameter, hardness (Shore A 20°-90°), and color (black, red, transparent, etc.), with tight tolerance (±0.05mm for precision grade) to ensure a perfect fit with your equipment.
- Superior Sealing & Durability: Advanced vulcanization technology enhances elasticity and anti-aging performance, with a compression set of less than 10% (at 150℃ for 24h), ensuring long-term airtight and watertight sealing without deformation or leakage. The O-ring is wear-resistant, tear-resistant, and不易 aging, reducing replacement frequency and maintenance costs.
- Food & Medical Grade Compliance: , making them safe for food contact, medical devices, and pharmaceutical applications. Non-toxic, eco-friendly, and odorless, with no harmful substances released during use.
- Wide Environmental Adaptability: Resistant to UV radiation, weathering, and most neutral solvents, suitable for both indoor and outdoor applications. It performs stably in static and dynamic sealing scenarios, withstanding pressure up to 40Mpa and adapting to uneven surfaces effortlessly.
