A method and sealing gasket are shown for providing a sealing joint between a spigot section and a socket section of low pressure plastic pipe, such as drain waste vent pipe that require a minimum of tools and operational steps to complete. The sealing gasket is installed in one of the sections to be joined and the spigot section is inserted within a mouth opening of the socket section with the sections being pressed together in a single operation, thereby forming both the joint and the seal. The sealing gasket is a composite gasket made with one section of a hard plastic material and one section of a thermoplastic elastomer material. No glue or adhesive is required.

A self-installing connector for a liquid cooling system of a datacenter component rack system. A datacenter component rack may include manifolds for conveying coolant to or from one or more datacenter electronic components for liquid cooling components of the datacenter electronic component. The self-installing connector provides a fluid connection between the manifold and a liquid cooling system of a datacenter electronic component. The self-installing connector may puncture the manifold at the time the datacenter electronic component is installed. The self-installing connector may form an opening in the manifold and secure one end of the self-installing connector into the opening upon installation of the datacenter electronic component into the datacenter component rack. The self-installing connector can separate at a dripless quick-disconnect coupling for datacenter electronic component maintenance.

A mechanical joint restraint includes: a gasket defining an inner surface and an outer surface, the inner surface defining a bore, the bore defining an axis therethrough, the gasket defining a first gasket end and a second gasket end; a gland defining a bore defining an axis and positioned axially outward from the gasket with respect to the first gasket end with the mechanical joint restraint in an assembled condition, the axis of the gland aligned collinearly with the axis of the gasket; a gripping ring positioned between the gasket and the gland, the gripping ring being a split ring defining a pair of circumferential ends and a gap therebetween; and a bridge engaging each of the pair of circumferential ends of the gripping ring and extending in a circumferential direction of the gripping ring across the gap therebetween with the mechanical joint restraint in the assembled condition.

A seal assembly is configured for use at PVCO pipe junctions. The seal assembly includes a main seal body made of a monolithic resilient material, such as rubber, and a stiffener. The seal has a stiffener pocket sized and configured to accept the stiffener, such that the stiffener can be assembled to the seal body by hand. This assembly can then be installed into the bell end of a first PVCO pipe, and a spigot end of a second PVCO pipe may then be inserted into the bell end and engaged with a main sealing lobe of the seal assembly. The seal assembly is configured to reliably withstand the insertion process, without damage or degradation to the sealing structures. Once installed, the seal assembly provides a robust fluid-tight seal along all potential leak paths between the seal assembly and the first and second pipes.

A tube quick-release assembly includes an outer socket and an inner plug. The inner plug is movably inserted in the outer socket. An upper portion of the outer socket is formed with two opposing engaging openings. An engaging buckle is fitted on the inner plug. The engaging buckle is provided with two opposing engaging legs having hooks and flaring outward. The hooks of the engaging buckle radially engage with the two engaging openings of the outer socket to realize a quick connection of tubes. The two hooks of the engaging buckle can be pressed inward to realize a quick disconnection of tubes.

The present disclosure relates to an apparatus for connecting to the end of a duct, the apparatus comprising: an outer ring having a central axis (C) and an inner surface extending between a first axial end and a second axial end of the outer ring; and an inner ring positioned within the outer ring and having a central axis (C) and an outer surface extending between a first and second axial end of the inner ring. A gap is provided between the outer surface of the inner ring at its first end and the inner surface of the outer ring at its first end, the gap extending in the direction of the second ends of the inner and outer rings.
