ABSTRACT:
An apparatus is provided for sealing around shafts or tubes of varying diameter. Its basic element comprises an elastomeric sealing body with an axial passage which is radially compressed from more than two sides to compress the passage into sealing engagement with a member extending through the passage. Radial compression is achieved by cams and followers disposed around the body which cooperate with angularly spaced radially extending lugs formed integrally with the body. The cams are spring biased to normally compress the axial passage of the sealing body. Levers operable by one hand of the user are provided to selectively release the apparatus.
