The sealing characteristics between a turned surface of soft material such as copper and a smooth seal surface of a rigid steel ball in static contact were investigated. This seal surface received not only a normal force but also a tangential force. The following results were obtained from calculations using a model that considered surface roughness on a turned seal surface as a wedge-shaped asperity, and gas leakage tests. ( 1 ) The linear sealing load P_c/l decreased with a decrease in the conical half-angle θ of the conical inside-seal surface. In the case of a surface roughness of 8 μm, the value of P_c/l at θ=15° was about 0.4 times that at θ=60°. ( 2 )The recommended values of θ were in the range of 5° to 35°, and the P_c/l values corresponding to this range were predicted.
