A system and method are provided for abandoning a tee assembly. The tee assembly comprises a tee member, a plug, and a retention member. The tee member is coupled to a conduit and defines a main passage and a branch passage. The main passage extends into the conduit, and the branch passage extends to the main passage. The plug is slideably disposed in the branch passage and extends at least partially into the main passage. The retention member is slideably disposed in the main passage and configured to interlock with the plug within the main passage. The plug is substantially prevented from sliding out of the branch passage when the plug is interlocked with the retention member.

A pipe fitting configured to be coupled to a pipe, the pipe fitting including a body that is elongate along a central axis that extends in a longitudinal direction, the body including a shell, a stiffener, and a shell-stiffener. The shell includes a shell inner surface that defines a shell through hole that extends through the shell in the longitudinal direction. The stiffener is positioned within the shell through hole, and the stiffener includes a shell outer surface that faces the shell inner surface such that the stiffener outer surface and the shell inner surface cooperate to define a pocket configured to receive the pipe. The shell-stiffener seal member includes a first seal member and a second seal member aligned in a radial direction, which is perpendicular to the longitudinal direction.

Pipe fitting with inner and outer seals

A tapping tee assembly and method is provided for fluidly connecting to a conduit. The tapping tee assembly includes a body having a conduit recess for receiving the conduit and further defining a passage having one end adjacent the conduit recess. A cutter is received in the passage and engages a threaded region of the passage for selective advancement and retraction within the passage upon rotation relative the body. The cutter comprises a first component with first and second ends and having a cutting edge at the first end for cutting through a side wall of the conduit to establish fluid communication between the main passage and the conduit. A second component is secured to the first component at the second end either by mechanically securing or molding the second component to the first component.

A valve operable with an associated fluid delivery system having fluid flow therethrough includes a housing, a valve body and a resetable excess flow valve. The housing has a first passage and the valve body is disposed along the first passage and including a wall at least partially defining a second passage. The excess flow valve is supported along one of the first and second passages. The valve body is displaceable between a first position permitting flow through the second passage and a second position substantially shutting-off fluid flow and resetting the excess flow valve.

Combination shut-off and resetable excess flow valve

A riser assembly is provided for transmitting gas from a buried line to a meter manifold. The riser assembly includes an adapter having a mounting structure at one end for connection to a manifold and having an opening at an opposite end. An inner casing has a first end received through the opening and a second end extending therefrom for connection with an associated buried line. A seal assembly is interposed between the inner casing and the adapter for sealing therebetween. A gripping assembly holds the inner casing in the adapter. A protective tubular assembly is received over the inner casing. The tubular assembly has a first end received in the opening and a second end extending therefrom a dimension sufficient to cover the inner casing above ground. The protective tubular assembly includes a steel liner received over the inner casing for protecting the inner casing, an anticorrosive coating received on the steel liner and a plastic jacket received over the coating and the liner for providing a protective barrier thereto.

A heat trap assembly for a hot water tank includes a heat trap insert and a sealing member retained by the heat trap insert. The heat trap insert includes a seat having an opening that is dimensioned to be covered by the sealing member when no water is flowing through the assembly. The heat trap insert also includes a plurality of fingers to retain the sealing member when water is flowing through the heat trap assembly.

A method of replacing a gas main that supplies gas to a recipient through an existing service line includes connecting a first tapping tee to the new gas main and connecting a second tapping tee to the existing service line that communicates with a downstream recipient. Branch passages of the first and second tapping tees are fluidically connected together by a connecting conduit. The new gas main is then tapped with the first tee so that gas flows from the new gas main into the connecting conduit up to the second tee. All air is bled from the connecting conduit between the first and second tees, and the existing service line is then tapped with the second tee so that gas is supplied to the recipient through both the existing service line and the connecting conduit. Gas flow to the recipient from the old main is then terminated. The second tee is a specially configured tapping tee specifically adapted for bleeding air from the connecting conduit that interconnects the first and second tees. This tee also utilizes a non-cylindrical bore for holding the conduit to be tapped to inhibit collapsing of the conduit during tapping operations.

No interrupt service tee and method

A connector adapted for use with an associated fluid line includes a connector body having a passage dimensioned to receive the associated fluid line and a capturing member supported on said connector body. The capturing member is suitable for retaining the associated fluid line in the passage. A sealing member is disposed within the passage and is suitable for forming a fluid-tight seal between the connector body and the associated fluid line. A stiffening member is disposed within the connector body along the passage, and an indicator is disposed within the connector body and is adapted to indicate that the associated fluid line has been received a predetermined distance into the passage.

Connector with fluid line installation indicator

A coupling body has: (i) a central member; (ii) a first retaining member; and, (iii) a second retaining member. The first retaining member and the central member define a first pipe receiving region. The second retaining member and the central member define a second pipe receiving region having a tapered inner surface. A selectively constrictable clamp collar is located in the first pipe receiving region. A bolt or other actuation member is operably engaged with the clamp collar and is movable to constrict the clamp collar. A gripping collet is located in the second pipe receiving region and includes a tapered outer surface. At least one tie-bolt or other fastener extends between the retaining members and is selectively adjustable to draw the first and second retaining members toward each other so that the tapered inner surface engages the tapered outer surface of the collet to constrict the collet radially.
