Description
Polyurethane (PU) seals are advanced sealing components widely used in hydraulic and pneumatic systems to prevent leakage and ensure efficient operation under high pressure and dynamic conditions. Known for their excellent abrasion resistance, elasticity, and load-bearing capacity, PU seals offer superior performance compared to conventional rubber seals.
Our PU seals are manufactured using high-quality polyurethane materials with hardness ranging from 70 Shore A to 95 Shore A, making them suitable for both medium and heavy-duty applications. These seals provide excellent resistance to wear, oil, chemicals, and high-pressure environments, ensuring long-lasting and reliable performance.
We offer a wide range of PU seals including rod seals, piston seals, wiper seals, and custom-designed profiles as per client drawings or samples. Precision manufacturing ensures accurate dimensions, tight sealing performance, and smooth operation even under demanding conditions.
Our PU seals are widely used in hydraulic cylinders, pneumatic systems, construction equipment, automotive applications, injection molding machines, and industrial machinery where leakage prevention and durability are critical.
