초록

A closet flange with a body portion having a tapered end and a plurality of grooves circumferentially disposed about the tapered end. The grooves increase in diameter in the upstream direction and are configured to receive an elastic O-ring. As the closet flange is inserted into a drain pipe the O-ring travels from groove to groove providing an increasingly tighter fit. The flange is installed without tools by pushing the flange into the end of the pipe until the desired tightness is achieved.
