SLIP-ON COUPLING GASKET
First Claim
1. A method of installing a pipe coupling to connect a first pipe element to a second pipe element, the method comprising:
- sliding the pipe coupling as a preassembled unit over an outermost surface of the first pipe element, the pipe coupling comprising a coupling segment and an annular gasket, the annular gasket comprising an annular body and a pair of sealing ribs extending substantially radially inward from the annular body, each sealing rib comprising a sealing ridge defining a sealing surface, the sealing surface of each sealing ridge being coannular in an undeformed state;
introducing an end of the second pipe element to an end of the first pipe element to place the first pipe element and the second pipe element in end-facing relationship;
aligning the pipe coupling over the first pipe element and the second pipe element; and
securing the coupling to the first pipe element and the second pipe element.

10. A method of installing a pipe coupling to connect a first pipe element to a second pipe element, the method comprising:
-
sliding the pipe coupling as a preassembled unit over an outermost surface of the first pipe element, the pipe coupling comprising a coupling segment and an annular gasket having an innermost diameter greater than a diameter of the outermost surface of the first pipe element and a diameter of the outermost surface of the second pipe element, the annular gasket comprising an annular body and a pair of sealing ribs extending substantially radially inward from the annular body, each sealing rib comprising a sealing ridge defining a sealing surface, the annular gasket configured to slide over the diameters of the outermost surface of the first pipe element and the outermost surface of the second pipe element without contacting the outermost surfaces of the first pipe element and the second pipe element in an undeformed state; introducing an end of the second pipe element to an end of the first pipe element to place the first pipe element and the second pipe element in end-facing relationship; aligning the pipe coupling over the first pipe element and the second pipe element; and securing the coupling to the first pipe element and the second pipe element. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
