摘要：
A sealing arrangement for the pin and box of a threaded connection between tubular members includes annular piston means for positioning in the box of one of the tubular members. Resilient seal means supported on the piston means seals between the pin end, box and piston means when the pin is threadedly engaged in the box. Additional seal means on the piston means is responsive to fluid pressure in the tubular members whereby the piston means may be urged toward sealing engagement with the pin end and the resilient seal means.
