The invention relates to a pipe, in particular a plastic pipe for wastewater lines, which has at least one socket end which is provided with an annular bead (4) and a socket neck (3) and forms a first pipe (1) into the socket end of which the spigot end of a second pipe or shaped part (13) can be plugged and removed again therefrom, and in which an elastic annular seal (6) is inserted into the annular bead (4). According to the invention, the socket neck (3) of the pipe is provided with a screw thread (9) onto which there can be screwed a screw ring (8) which comprises an inner ring part (10) and an outer ring part (11) between which an annular gap is formed, and the ring parts (10, 11) are connected by means of a ring base (12) facing away from the annular bead (4), wherein, upon screwing the screw ring (8) onto the screw thread (9), the front edge (14) of the inner ring part (10) compresses the annular seal (6) inserted into the annular bead (4) and arrests the spigot end of the second pipe or shaped part (13) in the first pipe (1).

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 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 pipe sealing gasket is shown which is designed to be received within a raceway provided within a socket end of a female bell plastic pipe end which is assembled with a mating male pipe end to form a plastic pipe joint. The raceway in the female bell plastic pipe end is preformed during manufacture and the gasket is installed thereafter. The gasket has a rubber body portion which is reinforced by a hard plastic band formed as a series of integral, spaced wedges which are interconnected by a flexible ribbon. The gasket is flexible enough to be flexed and placed in the pipe raceway and yet the hard plastic band acts to prevent extrusion of the gasket during a variety of pressure conditions as well as preventing displacement during field assembly.

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 universal fluid system connector creates an airtight seal between a variety of smoke evacuation system receptacles and various hoses. The universal connector includes a body and a seal having a plurality of radially extending flexible fins. A plurality of fins on the seal are disposed along the length of the body with the outer edges of the fins forming a frustoconical shape. The fins also include one or more flexion zones of various stiffness and one or more flexible fin extensions. The fins deform against the inner wall of a receptacle and form an airtight friction fit between the universal connector and the receptacle, regardless of the taper angle, size, threads, or other features of the receptacle.

A gasket for sealing a gap between a through hole formed on a wall body and a pipe to be inserted into the through hole, the gasket being provided for the pipe and made of tubular elastic material, the gasket having an inner circumferential lip portion which elastically contacts an outer circumferential face of the pipe; and an outer circumferential lip portion which elastically contacts an inner circumferential face of the through hole; an inner seal area on an inner circumferential side where the inner circumferential lip portion is provided is located at a position so that the inner seal area does not overlap in a radial direction with an outer seal area of an outer circumferential side where the outer circumferential lip portion is provided.
