A seal for a valve such as a faucet, has an annular body in which a resilient "O" ring is trapped on the main face by a frusto-conical wedging member. The seal may be a movable valve member (jumper) or may be a separate washer with a portion of the "O" ring protruding from the main face. The main "O" ring functions as the main seal against a flat or ridged valve seat of a faucet or other valve. |
