One of the most persistent problems in the design of hydraulic systems is sealing of the operating fluid in many types of machinery. Synthetic-rubber O-ring seals is being used successfully for the static, reciprocating and rotating pistons. In this report, the authors have experimentally investigated the oil leakage from an O-ring Packing used for the gascket packing. The results are : 1) O-ring must be radially compressed between the bottom of the seal groove and the cylinder wall or the flat plate for proper sealing action. This compressive force is proportional to the 4.5th powers of the J.I.S. hardness of O-ring materials. 2) The seals can be made perfectly leakproof for static conditions for oil pressure up to 280 kg/cm^2 (limit of test pressure) 3) According to the "self-sealing principle" and the experimental results, O-ring can be used for the collar instead of the seal groove. 4) In order to withstand the high pressurers, setting of the O-ring packings are designed so that cover plate have no deflection in the working state.
