Publication number: 20150376887Abstract: A toilet seal for sealing between a plumbing fixture discharge and a waste drainpipe outlet is described. The toilet seal comprises a flange member having an inwardly extending flexible lip and one or more raised ridges defining an annular seal extending upwardly from an upper surface of the flange member. The toilet seal further includes a radiused wall extending downwardly from the flange member, which cooperates with the flange member to define a cavity for receiving a compressible member. The toilet seal further comprises a flexible sleeve extending downwardly from the radiused wall. Related methods are described.Type: ApplicationFiled: September 2, 2015Publication date: December 31, 2015Inventors: Eduardo Coronado, Pedro Gonzalez, Adam Robert Sampson, Tuan Van Le, Krishnaditya Arkalgud

Publication number: 20140366256Abstract: The present disclosure generally relates to a toilet seal that is adaptable to conduits of different size. In one embodiment, the seal includes an integral sealing element coupled to an end of the sleeve. A modular sealing element is further disposed about the integral sealing element. The modular sealing element and integral sealing element are removable to thereby adapt the seal to conduits of different size. In another embodiment, the seal includes a first integral sealing element coupled to an end of the sleeve. The seal further includes a second integral sealing element coupled to the first integral sealing element. The first and second integral sealing elements are removable to thereby adapt the seal to conduits of different size.
