Abstract
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.
Claims24
A toilet seal assembly, comprising:
- a first toilet seal including:
- a first flange member having an inwardly extending flexible lip, the first flange member including a plurality of tabs extending outwardly of the first flexible sleeve, the tabs each including an opening disposed radially outward of the first flexible sleeve and operable to receive a fastener to secure the first toilet seal to a toilet flange;
- a first radiused wall extending downwardly from the first flange member, wherein a lower surface of the first flange member and the first radiused wall cooperate to define a cavity;
- a first flexible sleeve extending downwardly from the first radiused wall, wherein the first flexible sleeve includes a straight wall portion distinct from the first radiused wall, the straight wall portion being tapered such that an upper diameter of the straight wall portion is larger than a lower diameter of the straight wall portion;
- and
- a first compressible member disposed within the cavity;
- and
- a second toilet seal including:
- a second flange member having an inwardly extending flexible lip;
- a second radiused wall extending downwardly from the second flange member, wherein a lower surface of the second flange member and the second radiused wall cooperate to define a cavity;
- a second flexible sleeve extending downwardly from the second radiused wall, wherein the second flexible sleeve includes a straight wall portion distinct from the second radiused wall;
- and
- a second compressible member disposed within the cavity, wherein
- the first toilet seal is adapted to stack with the second toilet seal such that the tapered straight wall portion of the first toilet seal is disposed in the straight wall portion of the second toilet seal.

A method of sealing between a plumbing fixture discharge and a waste drainpipe outlet, comprising:
- providing a first toilet seal comprising a first flange member having an inwardly extending flexible lip, a first radiused wall extending downwardly from the flange member and a first flexible sleeve extending downwardly from the radiused wall, wherein the first flange member includes a plurality of tabs extending outwardly of the first flexible sleeve, the tabs each including an opening disposed radially outward of the first flexible sleeve and operable to receive a fastener to secure the first toilet seal to a toilet flange, a lower surface of the first flange member cooperates with the radiused wall to define a cavity for receiving a first compressible member, and the first flexible sleeve includes a straight wall portion distinct from the first radiused wall, the straight wall portion being tapered such that an upper diameter of the straight wall portion is larger than a lower diameter of the straight wall portion;
- providing a second toilet seal comprising a second flange member having an inwardly extending flexible lip, a second radiused wall extending downwardly from the flange member and a second flexible sleeve extending downwardly from the radiused wall, wherein a lower surface of the second flange member cooperates with the radiused wall to define a cavity for receiving a second compressible member, and the second flexible sleeve includes a straight wall portion distinct from the second radiused wall;
- positioning the second toilet seal over the waste drainpipe outlet;
- stacking the first toilet seal over the second toilet seal such that the tapered straight wall portion of the first toilet seal is disposed in the straight wall portion of the second toilet seal;
- and
- positioning the plumbing fixture discharge against the toilet seal.
