INDUSTRIES SERVED: Automotive , Industrial Equipment, Electronics, Oil and Gas Industry

As a leading manufacturer in China, we specialize in high performance custom polyurethane gaskets (also known as urethane gaskets) engineered for durability. Our urethane gaskets use high-grade cast materials, resisting oils, solvents, and temperatures can be customized from -40°C to 120°C(+160°C short term). They are ideal for demanding sealing tasks. Every polyurethane gasket undergoes strict quality checks, ensuring consistent performance that reduces leakage risks and maintenance needs.

Our polyurethane gaskets serve diverse industries: automotive (leak test seals for engine), food processing (FDA-compliant ), Electrical Equipment, and marine (saltwater-resistant fittings).They are Ideal for leak testing, fluid handling, and dynamic sealing systems across industries.

Applications of Urethane Gaskets

- Industrial Equipment: Suitable for pumps, compressors, valves, etc. It prevents liquid or gas leaks in environments with high pressure, high speed, and chemical media, ensuring stable equipment operation.

- Machine Tool Equipment: Used for sealing machine tool guards, guide rails, and lead screws. It keeps coolant and iron chips from entering the equipment interior, avoiding impacts on equipment precision and service life.

- Electrical Equipment: Used in computers, mobile phones, and home appliances. It provides dust - proof, water - proof, and moisture - proof protection, shielding internal electronic components from external environmental influences and improving product reliability and stability.

- Food Processing Industry: Used in the food processing industry because FDA-approved formulations provide excellent durability, resistance to wear, abrasion, and microbial growth. They are customizable to ensure leak-proof, hygienic seals for food processing equipment.

- Oil and Gas Industry: Serve as seals and gaskets for various parts of pipeline systems, valves, and pumps becasue of their excellent durability, resistance to abrasion, chemicals like gasoline and oils, and ability to maintain seals under pressure and extreme temperatures.

Advantages of Polyurethane Gaskets

- Excellent abrasion resistance: Handles frequent friction with no quick wear.

- Noise reduction for quieter operation.

- Features a non-marking surface, preventing scratches or stains on painted components.

- Blocks oil and petrol ingress reliably, avoiding damage from fuel or lubricant exposure.

- Keep good flexibility even at low temperatures, no stiffness or sealing failure in cold conditions.

- Cuts seal failure rates, minimizing equipment downtime.
