ODI is a U-shaped piston seal with an asymmetric sealing lip, a higher inner lip, and a lower outer lip. ODI is suitable for applications where standard rubber or fabric-reinforced rubber seals fail to meet performance requirements. It is primarily used for sealing pistons and plungers in heavy-duty mobile machinery or industrial hydraulic systems. We also supply low-temperature U-seals (-45℃~+100℃).
