A coupling sized for use with a pipe having a pipe outer diameter, the coupling including a pair of segments; and a gasket positioned between the pair of segments, the gasket including an annular body; and a pair of sealing ribs each extending substantially radially inwardly from the annular body, each sealing rib of the pair of sealing ribs defining a cylindrical sealing surface at an innermost radial extent in an uncompressed state, the cylindrical sealing surfaces each defining an inner gasket diameter that is larger than the pipe outer diameter when the gasket is in the uncompressed state.

Coupling gasket with multiple sealing surfaces

A mechanical branch outlet includes: a housing defining: an outer surface; an inner surface; and an outlet bore extending between the outer surface and the inner surface; an insert defining: a wall; an axis; a rim extending radially outward from the wall with respect to the axis, the rim being a flange; a first end extending from the rim in a first axial direction aligned with the axis; and a second end extending from the rim in a second axial direction opposite from the first axial direction; the first end received fully within the outlet bore of the housing; the outlet bore of the housing configured to slidably receive the second end and retain the first end, an outer diameter of the rim being greater than an outer diameter of the second end.

Mechanical branch outlet

A coupled pipe joint assembly includes a first pipe element defining a first end; a second pipe element defining a second end, the first end and the second end positioned together in an end-to-end facing relationship; and a coupling, the coupling including at least one segment, each segment defining a first end and a second end, the first end disposed opposite from the second end, each first end and each second end defining a fastener hole; at least one fastener, each fastener extending through at least a one of the fastener holes; and a gasket, each segment positioned annular to the gasket, the gasket including an annular body; a pair of sealing ribs each extending substantially radially inwardly from the annular body, and at least one center rib extending substantially radially inwardly from the annular body.

A mechanical branch outlet including: a housing having an outer surface and an inner surface and defining an outlet bore extending between the outer surface and the inner surface; and an insert having a first end and a second end, the outlet bore of the housing sized to receive the second end of the insert and retain the first end of the insert.

An annular gasket includes an annular body; an annular body; a pair of sealing ribs each extending substantially radially inwardly from the annular body and having an innermost radial extent; and at least one center rib extending substantially radially inwardly from the annular body, the at least one center rib having an innermost radial extent closer to the annular body than the innermost radial extent of each of the pair of sealing ribs.

A method of installing a pipe coupling to connect a first pipe element to a second pipe element includes 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.

Slip-on coupling gasket

A pipe joint assembly including a first pipe element, a second pipe element, a pair of segments, each segment defining a first end and a second end, each first end comprising a tongue and each second end comprising a groove, each groove defining a groove shoulder surface, the tongue of the one segment defining a tongue outer surface, the tongue outer surface of the tongue of the one segment angled at a non-zero angle relative to the groove shoulder surface in an assembled and untightened position, the tongue outer surface of the tongue positioned parallel and flush to the groove shoulder surface of the groove of the second segment in an assembled and tightened condition; and a pair of fasteners configured to deflect each segment around the first pipe element and the second pipe element in the assembled and tightened condition.

Coupling with tongue and groove

A method of coupling first and second pipe elements in end-to-end facing relationship includes obtaining a coupling, the coupling including an annular gasket, at least one segment, and a fastener, each segment being approximately semi-circular and including at least two ends, each end including at least one of a tongue and a groove, each tongue protruding circumferentially from at least one end, each groove defined circumferentially in at least one end; slipping the coupling onto the first pipe element beyond any groove proximate 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 into contact with the outer surfaces of the first and second pipe elements.

An annular gasket includes an annular body and an annular body and a pair of sealing ribs extending substantially radially inward from the annular body, each sealing rib having a sealing ridge, the sealing ridge of each of the pair of sealing ribs having a sealing surface, wherein the sealing surface is about cylindrical at rest.

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.
