Flexible toilet seal and method
The present disclosure generally relates to an improved toilet seal and methods for installing such toilet seals. The toilet seal includes one or more rings disposed circumferentially about a sleeve. The rings are removably attached to the sleeve to provide a manner by which to remove one or more of the rings and thereby adjust the position of the seal relative to adjacent piping. The seal further includes a sealing element that includes a flexible lip, which is adapted to deflect downwardly when engaged by a plumbing fixture.
1. A seal for connecting between a plumbing fixture discharge and a waste drainpipe outlet, comprising:
a flexible sleeve made from a material that permits a non-negligible angle of deflection of a lower portion of the sleeve relative to an upper portion of the sleeve;
a sealing element coupled to the upper portion of the sleeve, the sealing element including an inwardly extending flexible lip and an outwardly extending ring portion; and
an outwardly extending fixed ring disposed circumferentially about the sleeve and disposed a distance from the ring portion of the sealing element operable to rest on a supporting surface to accommodate differences in height between objects for sealing, wherein
the ring has a region of uniform thickness extending orthogonal to a central axis of the sleeve, and
the ring is integrally formed with the sleeve.
2. The seal according to claim 1 , wherein the region of uniform thickness is spaced from the sleeve.
3. The seal according to claim 1 , wherein the ring is disposed incompletely about the sleeve so as to contain a gap.
4. The seal according to claim 1 , further comprising a second ring disposed circumferentially about the sleeve and spaced from the ring portion of the sealing element.
5. The seal according to claim 1 , wherein the ring has a region of decreasing thickness, and wherein the ring is attached to the sleeve at a region of decreasing thickness.
6. The seal according to claim 1 , wherein the ring includes a notch formed therein.
7. The seal according to claim 1 , wherein
the seal includes another sealing element disposed at the lower portion of the sleeve.
8. The seal according to claim 7 , wherein the another sealing element is integrally formed with the sleeve.
9. The seal according to claim 7 , wherein the another sealing element is a separate element not integrally formed with the sleeve.
10. The seal according to claim 7 , wherein the another sealing element is an O-ring.
11. The seal according to claim 7 , wherein an outer diameter of the ring is greater than an outer diameter of the another sealing element.
12. The seal according to claim 1 , wherein the seal is adjustable in a longitudinal direction.
13. The seal according to claim 1 , wherein the ring does not extend fully around the sleeve so as to define a gap.
14. The seal according to claim 1 , wherein the outwardly extending fixed ring is spaced from the outwardly extending ring portion of the sealing element in a longitudinal direction.
15. A toilet sealing assembly for connecting between a plumbing fixture discharge and a waste drainpipe outlet, comprising:
the seal of claim 1 ; and
a flange member disposed about the seal, the flange member adapted for engaging a surface.
16. The seal according to claim 1 , wherein the sleeve is capable of forming an angle of deflection between a longitudinal axis of the lower portion and a longitudinal axis of the upper portion of at least 10 degrees.
17. The seal according to claim 1 , further comprising the waste drainpipe outlet, wherein an outer diameter of the ring is greater than an inner diameter of the waste drainpipe outlet.
