ABSTRACT:
A packing member comprising an annular body having a circular groove extending axially thereinto through an end wall to form inner and outer sealing lips utilizes a resilient member embedded in the annular body to exert a radially directed force to a wall surface of the groove to actuate one of the sealing lips. The other sealing lip has a plurality of spaced-apart circular holes extending axially thereinto through the first end wall of the body. In one embodiment, the resilient member is a garter spring carried in a recess formed in the inner wall surface of the groove to actuate the inner sealing lip. In another embodiment, the resilient member is a curved solid rod carried in a recess formed in the outer wall surface of the groove to actuate the outer sealing lip.
