Designing and manufacturing all of Oil Seals, Rubber Gaskets, O-Rings, O-Ring Kits, Rubber Cord and so on. The O-Ring Kit can be used for CATERPILAR excavator.An O-ring, also known as a packing, or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface. The O-ring may be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring. Dynamic examples include rotating pump shafts and hydraulic cylinder pistons. O-rings are one of the most common seals used in machine design because they are inexpensive, easy to make, reliable, and have simple mounting requirements. They can seal tens of megapascals (thousands of psi) of pressure.36Size 396pcs(METRIC)      NO.METRICQTY(PCS)NO.METRICQTY(PCS)IDWDIDWDR-01NK-37026R-1912.372.6212R-02NK-37036R-2013.902.2612R-03NK-37046R-2120.302.6212R-0418.771.7812R-2233.002.6210R-052.801.9016R-2340.952.6210R-063.801.9016R-2424.403.1010R-074.801.9016R-2529.403.1010R-085.801.9016R-2634.403.1010R-096.801.9016R-2744.403.1010R-107.801.9016R-2822.103.5010R-119.802.4012R-2923.703.508R-1214.802.4012R-3029.703.5010R-1315.802.4012R-3134.703.508R-1419.802.4012R-3235.703.508R-1520.802.4012R-3347.703.508R-1621.802.4014R-3449.703.508R-179.202.6212R-3528.173.538R-1810.772.6212R-3632.903.538
