A tubing nut fastener having elements that are partially rotatable with respect to each other. In between the rotatable elements, engagement members (e.g., balls) are captured within interior channels. The partially rotatable elements include permanent markings or other non-removable visual indicators, which varies spatially depending on whether the tubing nut fastener is in a torqued state or an un-torqued state, thereby providing a visual indication of the status of the tubing nut fastener.

Compression fitting with visual torque indicator

An apparatus comprising an inner ferrule and an outer ferrule. The inner ferrule comprises a plurality of engagement sections that define a plurality of gaps between the plurality of engagement sections. The outer ferrule is disposed around at least a portion of the inner ferrule. The outer ferrule comprises an engagement area mechanically joined to the plurality of engagement sections to join the inner ferrule to the outer ferrule.

Ferrule coupling for joining ducts together

A fitting assembly configured to visibly indicate nut tightness when coupling a first component to a second component is disclosed. The fitting assembly comprises a nut comprising a threaded portion and a chamber portion, wherein the chamber portion comprises one or more through-holes. The fitting assembly also comprises an indicator slidably disposed within the chamber portion, a retainer assembly disposed within the chamber portion and configured to interlock with an inner surface of the nut, and a spring disposed within the chamber portion between, and engaging, the indicator and the retainer assembly. The retainer assembly is configured to interface with the spring to retain the spring within the chamber portion. The fitting assembly is configured to receive the first component and the second component such that, when the nut is rotated, a visibility of the indicator through the one or more through-holes changes.

Coupling nut visible tightness indicator

A tube fitting including a sleeve member having a circumferential collar portion, the circumferential collar portion including a first tapered surface, a first coupling member having a circumferential engagement flange portion configured to couple with the circumferential collar portion of the sleeve member, and a second coupling member that includes a longitudinally extended sealing portion. The longitudinally extended sealing portion includes a second tapered surface that couples with the first tapered surface so as to circumferentially expand the longitudinally extended sealing portion, when the first tapered surface and the second tapered surface are coupled to each other, and form a fluid seal between the second coupling member and the sleeve member.

Tube fitting

A flexible dual duct coupling, comprising: a coupling body having an inner flow passage and an outer flow passage therethrough; a first nut assembly configured for reversible attachment to the coupling body; and, a second nut assembly configured for reversible attachment to the coupling body, wherein the second nut assembly is opposite the first nut assembly.

Dual duct flexible coupling apparatus and methods of use

A tube fitting includes a first coupling member having at least a snap coupling, a second coupling member having a first quick-connect side with a mating snap coupling disposed at a first end of the second coupling member, and at least one elastomeric seal disposed on the second coupling member, and a sleeve member configured to interface with the first coupling member and the at least one elastomeric seal, wherein the sleeve member is disposed between and retained by the first coupling member and the second coupling member and the snap coupling and mating snap coupling effect coupling of the first coupling member and the second coupling member.

A method and apparatus for electrostatically bonding coaxial tubing. An outer tube comprises an electrically conductive material and has an inner surface. An inner tube comprises material and has an outer surface. The inner tube and the outer tube are positioned to define a channel. A bridging structure comprising an electrically conductive material is positioned such that the bridging structure forms mechanical contact and an electrostatic connection between electrically conductive material on the tubes. The bridging structure is in mechanical contact with the inner surface of the outer tube at a first plurality of points and in mechanical contact with the outer surface of the inner tube at a second plurality of points.

Electrostatic bonding of coaxial tubing

A tube fitting including a first coupling member having at least a snap coupling, and a second coupling member having a first quick-connect side having a mating snap coupling disposed at a first end of the second coupling member, and a second quick-connect side configured for threaded engagement disposed at a second end of the second coupling member, the second end being opposite the first end, wherein the mating snap coupling is configured to engage the snap coupling to effect coupling of the first and second coupling member.

A tube fitting including a first fitting member having a cylindrical body including a flange, a second fitting member having a cylindrical body including a plurality of tines extending from the cylindrical body, the plurality of tines being configured to engage the flange where the plurality of tines and the flange are configured to secure the first and second fitting members to each other, and at least one seal disposed between the first fitting member and the second fitting member.

A method and apparatus for insulating a fluid line in a container configured to contain a fluid. The apparatus comprises a container, a fluid line in the container, and a tube. The container is configured to contain a fluid. The tube is placed around the fluid line in the container to form a channel around a first portion of the fluid line. The tube is configured to contain the fluid from the container in the channel and to prevent a first flow of the fluid between the container and the channel except through a number of ends of the tube. The tube is further configured to reduce a second flow of the fluid within the channel such that the fluid in the channel insulates the fluid line.
