An example fitting includes: a fitting body having counterbore, where the counterbore defines an annular shoulder within tire fitting body: a spring having a first end interfacing with the annular shoulder of the counterbore; and a seal carrier having: (i) a first end face interfacing with a second end of the spring, (ii) a second end face configured to interface with an internal surface of a port, such that the spring is configured to apply a biasing force on the seal carrier toward the internal surface of the port, (iii) a first annular groove on an exterior peripheral surface of the seal carrier, where the first annular groove is configured to have a radial seal disposed therein, and (iv) a second annular groove in the second end face, where the second annular groove is configured to have a face seal disposed therein.

A seal assembly includes a connector body having an open end configured for receiving a free end of a pipe and an adaptor for securing at the free end of the pipe. The adaptor has a first ring, configured to be mounted around the circumference of the free end of a pipe, and a second ring configured to cooperate with the first ring in order to drive the first ring into engagement with an outer surface of the pipe. A mechanical interlock arrangement is configured for driving the adaptor in the direction of the connector body, when the adaptor is secured at the free end of the pipe. The mechanical interlock arrangement is further configured for preventing or limiting axial movement of the pipe relative to the connector body, when the adaptor is secured to the outer surface of the pipe and when the free end of the pipe is in sealing contact with a metal seal surface of the connector body.

A fluid coupler including a ferrule adapter having a body with a receiving bore for receiving a fluid conduit, a stop axially spaced away from the body and configured to engage an end of the fluid conduit, and a connector configured to adjust the axial distance between the body and the stop.

A support ring for a tubular connection is provided that comprises a body comprising a first end and a second end. A circumferential ring lip extends from the first end of the body and positioned perpendicular to the body. A protrusion is positioned on the body between the first end and the second end. The protrusion comprises a top surface and a bottom surface.

A pipe joint formed between pin and box sections is disclosed. The pin and box sections each have a tubular pipe section, engaging at respective first ends in end-to-end arrangement and having a seal element partially therebetween. The box section includes a generally cylindrical box stress collar extending from the first end, and axially aligned with the tubular box pipe section. The inner diameter of the box pipe section is of the same size as the outer diameter of the pin section.

The pin and the box sections are secured together by securing means housed in the box collar and actuable by exertion of radial pressure to urge the pin and box into sealing arrangement.

The pin section includes a circumferential collar located to engage a profiled end surface of the box stress collar on make-up of the joint, the circumferential collar including a circumferential pin channel, the profiled end surface of the box section including a box channel, the circumferential pin channel housing the inner rim of the box and the box channel housing the pin edge rim.

Disclosed is an invention relating to a connection device which includes: a housing unit having a pipe inserted therein; a fixing unit that is inserted between the pipe and the housing unit by rotation to fix the pipe; and a sealing unit provided between the housing unit and the pipe to seal between the housing unit and the pipe.

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).
