A single piece structural connector is provided that includes a single machined aluminum piece having first and second circular ends including a plurality of bolt holes and a center hole. The connector also includes an alignment dowel positioned on the center hole. The alignment dowel is configured to tightly fit into a center hole of a pipe plate.

A seal assembly has a connector body with a first section and a second section, movable relative to one another. The first section and the second section each has an open end configured for receiving the free end of a pipe. The open end of the first and second sections are each configured for sealing engagement with the free end of a respective pipe. The seal assembly is movable between a first condition, in which the second section assumes a retracted position relative to the first section, and a second condition in which the second section assumes an extended position relative to the first section. A seal member is provided for creating a seal between the first section and the second sections in said first and second conditions. First and second adaptors are provided, each for association with a respective one of said first and second sections of the connector body and configured for securing at the free end of a respective pipe. First and second mechanical interlock arrangements are provided, each for association with a respective one of said first and second adaptors, and each configured for driving the respective adaptor in the direction of the connector body.

A piping element assembly includes a coupling body and at least one gasket, the coupling body defining an interior cavity, the interior cavity in contact with the at least one gasket, the piping element assembly adapted for sealably connecting two lengths of pipe by insertion of the pipe lengths within the interior cavity and sealed by the at least one gasket.

A pipe adapter assembly comprising a housing that includes a lumen for fluid communication between a first end and a second end along the lumen and a bore positioned inwardly from said first end. An insert having a passage that includes a plurality of teeth and having a tapered outer surface with at least one slot. A grip actuator that includes a flanged body and a protrusion wherein said protrusion includes a generally circular configuration and is configured to fit within the bore of the housing. An abutment surface of the protrusion positioned radially inwardly relative to a perimeter of the protrusion that extends concentrically about an aperture through the grip actuator wherein the pipe adapter is configured to receive a pipe member through said lumen, passage, and aperture and wherein the pipe adapter is configured to selectively lock the housing to the pipe member.

A coupling for joining pipe elements has segments surrounding a central space with cusps which engage lobes of a seal to maintain the segments in spaced apart relation in a preassembled state. While the coupling is in the preassembled state the pipe elements may be inserted into the central space without disassembling the coupling, and portions of the seal adjacent to attachment members on the segments seat within a channel defined by the segments between the cusps. The lobes of the seal contact a second surface of the shoulders of the segments adjacent to the attachment members when the segments are in spaced relation.

The present disclosure provides a fluid introducer for a piping system that includes first and second piping sections. The fluid introducer provides a direct connection to the first piping section through a separator body configured to be positioned in an expansion gap between the first piping section and the second piping section such that a first end face of the separator body faces the first piping section and a second end face of the separator body faces the second piping section. The fluid introducer is configured to direct fluid from the fluid source through fluid introduction passaging into the first piping section and block the fluid from flowing into the second piping section.

An end ring assembly includes a split ring defining an outer ring surface, an inner ring surface, a first ring end and a second ring end, the first ring end and second ring end defining a gap therebetween; a gasket bridge defining an outer bridge surface, an inner bridge surface, the gasket bridge further defining a first bridge end, a second bridge end, and a middle portion therebetween, the middle portion of the gasket bridge extending between the first ring end and the second ring end, the first bridge end and second bridge end engaging the inner ring surface, a first ramp extending from the first bridge end; and a primary gasket defining a primary outer sealing surface and a primary inner sealing surface, the primary outer sealing surface engaging the inner ring surface and the inner bridge surface.

A pipe coupling has first and second segments attached end to end surrounding a central space. The segments define first and second receptacles which receive pipe elements. A port is positioned in one of the segments. The port provides access to the central space. A nipple on the segment extends from the central space and defines a bore aligned with the port. A collar on the segment extends toward the central space. The collar has an outer surface which forms a recess with an inner surface of the segment. A seal is positioned within a channel defined by arcuate keys which surround the receptacles. The seal has a body which defines a first aperture aligned with the receptacles and a second aperture aligned with the bore of the nipple.
