FKM Material Seals ODU High Quality Piston Seal

O Rings Seals ODU type is a special piston seal suitable for the Chinese machinery and equipment market, and the groove design can adopt the Chinese standard JB/ZQ4264. Nitrile O Ring ODU application range: Working pressure: ≤32MPa (PU) Working temperature: -40℃～+80℃ (PU) Working pressure: ≤32MPa (NBR) Working temperature: -30℃～+100℃ (NBR) Reciprocating speed: ≤0.5m/s Media: mineral oil, air Note: To prevent extrusion, it is recommended to install a retaining ring on the heel of the seal when the pressure is above 140bar. Install: Seals such as Piston Sealing should have an axial clearance (see columns h and H in the table). Integral pistons are available. To avoid damage to the sealing lip, precautions should be taken to avoid sharp edges during installation. Material: KVK polyurethane material with a hardness of 90 degrees. High-performance NBR with a hardness of 88 degrees. Order example: ODU-100 88 14
