Method and system are provided for a quick connector for coupling conduits. The quick connector comprises a first piece including a first slot group, a second piece including a second slot group and a first protrusion group counterpart to the first slot group, and a third piece including a second protrusion group counterpart to the second slot group, where each slot of the first slot group angles in a first direction, and each slot of the second slot group angles in an opposing, second direction. In one example, the quick connector may include a locking mechanism and a feedback system.

A connector assembly is provided. The connector assembly includes a connector body, a movable component selectively movable between an uninstalled state and an installed state, a digital tag, and a digital blocker. When the movable component is moved from the uninstalled state to the installed state, the digital blocker is moved relative to the digital tag from a position where the digital tag is blocked by the digital blocker to a position where the digital tag is unblocked by the digital blocker, thereby providing a digital indication of a successful connection between the connector body and the movable component.

This disclosure relates to a quick connector adapted to display a code that verifies that a latch member is engaged to retain an installed pipe to the quick connector. The quick connector comprises a connector body having a receiving portion surrounding an internal passage, the internal passage arranged to receive the pipe therein. A latch member retained on the receiving portion is arranged to be movable between a pipe insertion position and a latched position. In the pipe insertion position, the latch member allows the pipe to be inserted into the internal passage. A code readable by a scanning device becomes readable when the latch member is moved to the latched position verifying that the pipe is installed and latched in the connector body.

A fluid connector in a fluid joint assembly such as in a machine hydraulic system includes a connector body having a stem with a seal face extending circumferentially around a connector axis at a backup sealing location. A non-metallic seal is upon the stem and extends circumferentially around the connector axis at a primary sealing location. The fluid connector also includes a swivel nut including threads and a snap retainer and supported for rotation upon the stem. The fluid connector can establish a primary sealing state by way of hand installation, and can be torqued to a backup sealing state to provide a robust metal-to-metal seal.

The disclosure relates to a plug connector and method for connecting pipes for liquid or gaseous media. The plug connector includes a connector body and a locking element. An indicator element is formed, which has an indicator surface, a first partial section and a second partial section, wherein the first partial section and the second partial section are flexibly coupled to one another by means of a spring section. The first partial section is connected to the locking element, and the indicator surface is formed on the second partial section, wherein the indicator element is formed such that, in a locking position of the locking element, the second partial section is deformed relative to the first partial section, so that the indicator surface is pushed into an indicator position.

Described herein is a technique capable of properly attaching a nozzle to a reaction tube. According to one aspect thereof, there is provided a nozzle installation jig including: a lower plate configured to make contact with a process vessel in a vicinity of a lower end opening of the process vessel in which a nozzle is provided; a frame fixed to the lower plate and extending upward with respect to the lower plate; an upper plate fixed to the frame and provided with a sensor configured to detect a position of the nozzle in the process vessel; and a notification device configured to transmit a notification to an operator according to a detection result of the sensor.

Disclosed are chromatography systems employing a releasable coupling (100) for holding a fluid tubing to a spigot, the coupling comprising: a cylindrical inner component (110) for accepting a fluid tubing (30), said inner component including a resiliently deflectable portion (118) arranged to urge an outer surface of the tubing toward a spigot; and a cylindrical collar (130) having and internal through-aperture (132) for slideably accepting the inner component, the aperture and resilient portion having complementary surface formations which in a first position of the collar mounted to the inner component provide for said resilient deflection in use, and which in a second different position do not cause said deflection, the coupling being characterized in that the collar comprises a collar flange (134) extending outwardly away from the aperture of a size allowing manual manipulation of the collar between the first and second positions. Chromatography systems employing said couplings is disclosed also.

Clamping system for connecting two tubes having protruding clamping surfaces. The system comprises a collar having a strip able to cooperate with the clamping surfaces. The strip has a first and a second flank between which an inner recess able to receive the clamping surfaces is delimited. The system has at least one retaining clip having a cross-member which extends across the inner recess, a first and a second wing which extend radially outwardly relative to the cross-member by covering the flanks and a first and a second retaining configuration each having at least one retaining lug. The cross-member is able to be deformed to penetrate into the inner recess.

A quick connector includes a male base and a female base, wherein the male base has a first tube body, an annular clamping groove arranged outside the first tube body, a first flow channel axially penetrating through the first tube body, a plug body slidably arranged in the first flow channel, and an elastic member for pushing the plug body to close the first flow channel. The female base includes a second tube body, a second flow channel which axially penetrates through the second tube body and into which the first tube body is inserted, an annular fastener provided in the second flow channel, and a push rod fixed on the second flow channel and oriented towards the plug body.

A joint body has tube connection holes each having an inner circumferential surface including a plurality of contact walls, which are equiangularly spaced about an axis of the tube connection hole and extend along the axis. A joint guide is cylindrical and includes a barb on its outer circumferential surface. The joint guide is configured such that, when the joint guide is press-fitted into the tube connection hole, the outer circumferential surface of the joint guide comes into contact with inner wall surfaces of the contact walls and the barb catches the contact walls.
