A ferrule includes a flange and an elongated sleeve extending from the flange. The flange and the elongated sleeve define a bore, which is configured to receive a length of flexible tubing. The elongated sleeve is configured to hold the flexible tubing within the bore via friction. For example, the elongated sleeve is configured to hold the flexible tubing within the bore without compressing the flexible tubing. In this manner, flow through the flexible tubing may be unrestricted. In some embodiments, a distance of flexible tubing contacted by the elongated sleeve is sufficient to hold the flexible tubing within the elongated sleeve without tightly holding or compressing the flexible tubing. This configuration can prevent narrow tubing from becoming blocked and/or the tubing bore can remain smooth (e.g., for accurate mixing, constant fluid flow, and so forth).

Provided herein are approaches for forming a connection with a conduit body. In one approach, an exemplary connector assembly a conduit body having a conduit inner surface opposing a conduit outer surface, at least a portion of the conduit inner surface being a threaded portion. The connector assembly may further include a compression ring extending from a first circumferential end to a second circumferential end, wherein the first circumferential end is complementarily engageable with the second circumferential end, wherein the compression ring includes a first axial end and a second axial end, and wherein the compression ring has a circumferential gap between the first circumferential end and the second circumferential end in an uncompressed configuration. The connector assembly may further include a bushing positioned within the threaded portion of the conduit inner surface of the conduit body.

An inner ring 4 of a pipe joint 1 includes a bulge portion 6 formed at an axially outer end portion thereof so as to project toward a radially outer side, and to be press-fitted into an end portion of a tube 8, and has a fluid flow passage 4a formed on a radially inner side of the bulge portion 6. The bulge portion 6 is formed so as to be tapered from an axially inner side toward an axially outer end thereof in an axial cross-sectional view, and has a flat surface 6e formed at the axially outer end thereof and extending in a radial direction.

A fitting element, in particular for an HPLC application, is configured for providing a fluidic coupling of a tubing to a fluidic device. The fitting element comprises a gripping piece to exert—upon coupling of the tubing to the fluidic device—a grip force (G) between the fitting element and the tubing. The gripping piece comprises a hydraulic element configured to transform an axial force (S) into a hydraulic pressure (P) within the hydraulic element. The hydraulic pressure (P) in the hydraulic element causes the grip force (G).

A rigid entry fitting configured to form a seal between a flexible pipe segment and a sump wall includes a fitting body having an inner surface defining a tapered opening, an insert received in the tapered opening, a shell received in an opening of the insert, a first pair of gaskets between an outer surface of the insert and the inner surface of the fitting body, a second pair of gaskets contacting an inner surface of the shell and opposite ends of the insert, and a nut configured to engage threads on an outer surface of the fitting body. When the nut is threaded onto the threads, the nut presses the shell and the insert into the tapered opening and presses the first pair of gaskets against the inner surface of the fitting body and the second pair of gaskets against the outer surface of the flexible pipe segment.

A locking pipe joint device employs a center body connector, one or more sealing elements, such as a wiper seal and a sealing ring, a sealing ring retainer, an indicator ring and a retaining cap. In various embodiments, the retaining cap and the center body connector include mating block members that permit sliding bolted connection along an axis perpendicular to the main axis of the center body connector, which allows the retaining cap to tighten the packing arrangement components around an inserted piping or tubing element, and in secure engagement with the interior of the center body connector.
