Product Features 1. Excellent Wear Resistance Made from high-performance polyurethane material, the IDI seal offers outstanding abrasion resistance . This ensures a long service life even in demanding working conditions with high cycle operations. 2. High Pressure Tolerance The IDI seal can withstand working pressures up to 40 MPa . It features high resistance against extrusion and remains stable under shock loads and pressure peaks . 3. Easy Installation The seal has good flexibility and low compression set, making installation easy without special tools . The U-shaped design provides proper pre-compression upon installation for effective sealing. 4. Good Sealing Performance The shorter inner sealing lip design improves sealing and compression set characteristics over conventional, symmetrical U-rings . The seal relies on pre-compression and system pressure to achieve reliable sealing . 5. Low Compression Set The PU material maintains its shape even after long-term compression, ensuring consistent sealing performance over time .
