Abstract

A sealing ring and a method of preventing or stopping a joint leak between a pipe and a pipe fitting to minimize property damage as well as clean up costs occurring from property damage due to joint leaks by securing a sealing ring to the pipe and the pipe fitting to form a secondary joint that inhibits or prevent leakage between the primary joint between the pipe and the pipe fitting.

Claims (12)

1. In combination:

a PVC pipe;

a cylindrical one-piece PVC split sealing ring having a first end and a second end; an annular end face and an annular pipe engagement surface with the sealing ring having sufficient flexibility so that a first end of the sealing ring and the second end of the sealing ring can be spread apart to allow lateral insertion of the sealing ring around the pipe with the sealing ring having sufficient resiliency to return to its original shape after the sealing ring is placed around the pipe;

a PVC pipe fitting located on the outside of said PVC pipe with said PVC pipe extending into said PVC pipe fitting, and having an annular bonded joint between the pipe and the pipe fitting that may or may not leak; and

a securement film present on either the annular pipe engagement surface of the split sealing ring or the external surface of the pipe or both, said sealing ring spaced from an end of the pipe in the pipe fitting with the annular end face of the sealing ring positionable along the pipe and into face to face engagement with an annular edge of the pipe fitting when the securement film is in an uncured state, said securement film securing said sealing ring proximate said pipe and said pipe fitting when the securement film is in a cured state to thereby inhibit or prevent leaks through the joint.

2. The combination of claim 1 wherein the sealing ring includes an annular surface having a diameter sufficiently larger than the diameter of the pipe so as to slide along an exterior pipe surface but sufficiently small so that a diametrical clearance between the exterior pipe surface and the annular surface on the sealing ring permits joining the exterior pipe surface and the annular surface securement film to each other.

3. The combination of claim 1 wherein the annular end face includes a further annular sealing surface located at a right angle to the annular end face.

4. The combination of claim 1 wherein the sealing ring includes an exterior surface having a plurality of radial protrusions to thereby help a user easily grip and rotate the sealing ring.

5. In combination:

a cylindrical one-piece, sealing ring having an annular end sealing surface and an annular pipe engagement surface;

a thermoplastic pipe and a thermoplastic pipe fitting having an annular bonded joint therebetween that may or may not leak; and

a securement film present on either the annular pipe engagement surface or the external surface of the pipe or both, said sealing ring annular end sealing surface positionable along the pipe and into engagement with an annular edge of the pipe fitting when the securement film is in an uncured state, said securement film securing said sealing ring proximate said pipe and said pipe fitting when the securement film is in a cured state to thereby inhibit or prevent leaks through the joint wherein the sealing ring is secured to the pipe fitting through a ruptureable member.
