Slip-on coupling
First Claim
1. A method of coupling first and second pipe elements in end-to-end facing relationship comprising:
- obtaining a coupling, the coupling includingat least one segment, each segment including at least one inner surface, at least one outer surface, at least two ends, and a fastener pad protruding proximate to each end, each fastener pad defining a fastener hole, each fastener hole having an axial length and a transverse length, wherein the transverse length is longer than the axial length, wherein the at least one segment includes a tongue, wherein a mating surface of the tongue is angled at a non-zero angle with respect to a horizontal axis of the segment;
an annular gasket contacting the inner surface of at least one segment, the annular gasket including at least one sealing surface directed radially inwardly and an outer surface directed radially outwardly; and
at least one fastener disposed within at least one fastener hole, each fastener including a head portion and a shaft portion, each shaft portion including at least one of a threaded portion, a shank portion, and a collar portion, wherein at least one portion of the shaft portion is sized to engage at least one fastener hole;
slipping the coupling onto the first pipe element beyond the end of the first pipe element;
aligning the second pipe element in end-to-end facing relationship with the first pipe element;
slipping the coupling onto the second pipe element such that the segments of the coupling straddle the ends of the first and second pipe elements; and
engaging each fastener to deform each segment in contact with the outer surfaces of the first and second pipe elements.

Abstract
A coupling includes at least one segment, each segment including at least one inner surface, at least one outer surface, at least two ends, and a fastener pad protruding proximate to each end, each fastener pad defining a fastener hole, each fastener hole having an axial length and a transverse length, wherein the transverse length is longer than the axial length; an annular gasket contacting the inner surface of at least one segment, the annular gasket including at least one sealing surface directed radially inwardly and an outer surface directed radially outwardly; and at least one fastener disposed within at least one fastener hole, each fastener including a head portion and a shaft portion, each shaft portion including at least one of a threaded portion, a shank portion, and a collar portion, wherein at least one portion of the shaft portion is sized to engage at least one fastener hole.
