A closet flange having a shoulder and a body portion extending therefrom, the body portion having a substantially cylindrical upstream portion and a smooth tapered downstream portion, the downstream portion configured to receive an elastic o-ring. The o-ring travels up the tapered portion as the closet flange is inserted into a drain pipe, providing an increasingly tighter seal between the closet flange and the pipe. O-rings of various outer diameters may be provided to accommodate pipes having different internal diameters. The flange is installed without tools by pushing the flange into the end of the pipe until the desired tightness is achieved.

[ I claim as my invention:] [1.]1. A closet flange for insertion into a drain pipe, comprising:a shoulder portion having a plurality of openings for accommodating means for securing the flange to a floor;a body portion extending from the shoulder portion in a downstream direction and defining an axis, said body portion having an upstream portion adjacent the shoulder portion and a downstream portion, said upstream portion being substantially cylindrical and having a constant outer diameter in the axial direction, said downstream portion being tapered such that its outside diameter increases in the upstream direction; anda toroidal o-ring disposed about the body downstream portion to provide a compression fit between the flange and the drain pipe, the o-ring being of sufficient elasticity to travel in an upstream direction along the downstream portion as the flange is inserted into the pipe to provide an increasingly tighter fit.
