Custom Silicone Gaskets for Reliable Sealing
Silicone gaskets are widely used across industries where reliable sealing, temperature resistance, and long-term durability are required. Compared with traditional rubber materials, silicone offers superior flexibility, chemical stability, and performance in extreme environments.
At Ukong, we manufacture custom silicone gaskets based on your drawings or samples, supporting OEM applications across industrial equipment, medical devices, and food processing systems.
Key Features of Silicone Gaskets
Our silicone sealing gaskets are engineered to deliver consistent performance in demanding environments.
• Wide Temperature Resistance
Operates reliably from −60°C to +200°C, with special formulations available for higher temperatures.
• Excellent Flexibility
Maintains elasticity over long-term use, even under compression and temperature cycling.
• Superior Sealing Performance
Provides airtight and watertight sealing for static and dynamic applications.
• Chemical & UV Resistance
Resistant to ozone, UV exposure, and a wide range of chemicals.
• Food & Medical Safety Options
Available in FDA-compliant and medical-grade silicone materials.
