Embodiments of an integrated piping conduit include a device having a center body with an interior surface having a tube stop extending radially inwardly thereof, one or more head connectors, and a packing arrangement comprising at least one sealing ring, a spacer gland and a grip ring maintained within a radial housing compartment of the one or more head connectors. The packing arrangement can further include a retainer ring. In various embodiments, each head connector is secured to the center body through gluing or ultrasonic welding.

Disclosed herein is a fluid connection port for forming a working fluid connection between a deformable, flexible tube and a fluid handling device, the fluid connection port comprising a bore extending from an exterior surface of the fluid handling device to an internal fluid handling feature, the bore comprising a narrow diameter bore section adjacent the exterior surface of the fluid handling device, a larger diameter bore section adjacent the internal fluid handling feature, and a shoulder separating the narrow diameter bore section and the larger diameter bore section, wherein the diameter of the bore at the narrow diameter bore section is less than the outside diameter of the deformable, flexible tube.

A flexible hose adapter configured for engagement with a coupling, the flexible hose adapter including an end piece, the end piece defining an inner end and an outer end, the end piece defining an axis extending from the inner end to the outer end, the end piece defining a raised lip, a sealing surface, and a groove, the raised lip axially positioned at the inner end, the sealing surface positioned between the raised lip and the groove; and a flexible hose attached to the outer end of the end piece.

A cap configured for engagement with a coupling can comprise an annular ring extending circumferentially around an outer portion of the cap, the cap defining an inner end and an outer end disposed opposite from the inner end, the annular ring defining a sealing surface between the inner end and the outer end, the annular ring defining a raised lip at the inner end, the raised lip extending radially outward from the sealing surface; and a web, the web enclosing the annular ring.

A connection assembly for a chromatograph is used for connection to a flow path of the chromatograph, and includes a tube, a housing and a ferrule. The housing has an opening into which an end portion of the tube forming the flow path is insertable. The ferrule is formed of resin having chemical resistance and holds the tube in the opening of the housing while surrounding the tube. The ferrule has an inner peripheral surface coming into contact with the tube and an outer peripheral surface coming into contact with the housing. The friction coefficient between the inner peripheral surface of the ferrule and the tube, and the friction coefficient between the outer peripheral surface and the housing are equal to or larger than 0.3.

A method for using a gland assembly includes sliding a gland assembly over an end of a pipe, the pipe defining an outer surface, the gland assembly comprising a gland, a joint restraint assembly, and a gasket, the joint restraint assembly comprising a gripper and a spring, the spring configured to engage the gripper and the gasket; inserting the end of the pipe into a socket of a piping element; fastening the gland to the piping element; disabling a deactivation mechanism of the joint restraint assembly; and engaging the joint restraint assembly with the outer surface of the pipe to prevent removal of the pipe from the piping element.

A flexible hose adapter configured for engagement with a coupling can comprise an end piece, the end piece defining an inner end and an outer end, the end piece defining an axis, the end piece defining a sealing surface and a raised lip, the raised lip defined between the inner end and the sealing surface; a flexible hose attached to the outer end of the end piece; and a socket end piece attached to the flexible hose opposite from the end piece.

The invention relates to a plastics pipeline comprising at least one pipeline end (1) and at least one support ring (2). It was the underlying object of the invention to improve a plastics pipeline of the type described at the outset in such a way that the support sleeve or the support ring (2) remains firmly connected to the pipeline even in the event of the plastics pipeline being stored in the presence of high air humidity and temperature. This object is achieved by virtue of the fact that the blow molded pipe section (1) runs through the support ring (2) and, as viewed radially, is pressed from the inside outward against the support ring (2), wherein the pipe section (1) engages around the support ring (2), such that the support ring (2), with its outer surface, and the pipe section (1), with its outer surface, are substantially in alignment.

A method of forming a tube assembly includes forming arms on a tube end portion by forming a plurality of slots or slits on such tube end and mating such arms with a tapered outer surface of a fitting. The fitting may include at least one annular step mated with an annular step formed on the tube inner surface.

A gland assembly and a method for using a gland assembly are disclosed. The gland assembly can comprise a gland, the gland defining a gland bore; a joint restraint assembly comprising; a restraint base formed on the gland; a gripper disposed within the restraint base; and a spring comprising a retention tab and an engagement leg, the engagement leg configured to engage the gripper; and a gasket defining a recess, the retention tab configured to engage the recess.
