An illustrative port assembly includes a male port assembly including a male frame sub-assembly having first and second hinged male frame members rotatable about a first axis, the first and second hinged male frame members being sealable therebetween. A first transfer sleeve is attachable to the male port assembly and is configured to operably connect the male port assembly with a first volume. A female port assembly includes a female frame sub-assembly having first and second hinged female frame members rotatable about a second axis that is coaxially alignable with the first axis. The first and second hinged female frame members are sealable therebetween, and the female frame sub-assembly is sealable with the male frame sub-assembly. A second transfer sleeve is attachable to the female port assembly and is configured to operably connect the female port assembly with a second volume.

A connector assembly is configured to fluidly and removably connect a first set of microtubes to a second set of microtubes of a microfluidic device. The connector assembly provides multiple points of contact to the microtubes to provide a secure connection between the connector assembly and the microtubes. A single gasket provides a securely aligned connection between microtubes.

A rotational high purity or ultra-high purity gas fitting or process cooling or critical process cooling water fitting comprising an inlet pipe, inlet flange, outlet flange, a compression mechanism (such as a nut and bolt mechanism), a rotational outlet pin comprising an interior flange, a sealing void, a sealing element, and an outlet pipe. The rotational high purity or ultra-high purity gas fitting or process cooling or critical process cooling water fitting provides a fitting wherein at least one end (inlet or outlet) is capable of a full 360 degree rotation clockwise or counterclockwise while maintaining a high purity and ultra-high purity gas seal or a or process cooling or critical process cooling water seal. Functional rotating ability in live and non-live systems (while gas or other medium is flowing).

The invention relates to a coupling component for a fluid coupling (1) for releasably connecting fluid-conveying components, in particular fluid-conveying components in medical equipment, wherein the coupling component comprises a coupling housing (14) through which a fluid channel (17) passes in regions and which is provided with a coupling recess (7) that is sunken into a surface (15) of the coupling housing (14), wherein a channel opening (18) of the fluid channel (17) ends at an end face (19) of the coupling recess (7). According to the invention, it is provided that the channel opening (18) is covered by a membrane seal (4) which is made of a resilient material and through which a fluid gap passes (8) that is designed such that the membrane seal (4), when in a resting position, seals the channel opening (18) and, when in an operative position, opens the channel opening (18), wherein at least one yielding depression (29) is formed in the coupling recess (7) adjacently to the channel opening (18), which depression is designed for an yielding movement of a region (36, 37) of the membrane seal (4) when the membrane seal (4) transitions from the resting position into the operative position.

One or more seals may be provided in a gap sub to prevent the ingress of drilling fluid into an insulating gap between a male member of the gap sub and a female member of the gap sub. A first seal may comprise an internal gap sub seal provided near the tip of the male member of the gap sub. A second seal may comprise an external gap sub seal provided near the tip of the female member of the gap sub. The first and second seals may comprise non-conductive materials. The first and second seals may each comprise one or more O-rings. The first and second seals may comprise one or more lips, protrusions or flanges to engage the male and/or female members of the gap sub for maintaining contact with the male and/or female members during deformation of the gap sub.

Provided is a fluid transfer connector plug that allows for easy engagement of keys with key grooves. The fluid transfer connector plug includes: a plug body having a proximal end and a distal end, the proximal end allowing a hose to be fixed thereto, the distal end being removably connected to a socket, the plug body including a fluid channel communicating with the hose; a key plate on an outer periphery of the plug body, the key plate being rotatable relative to the plug body; and two or more keys on the key plate. The plug further includes a main key having a larger circumferential width than that of each of the other keys.

Swivel joints comprise a male sub, a female sub, annular races, ball bearings, a replaceable sleeve, and first and second pressure seals. The male sub is rotationally coupled to the female sub at, respective, generally tubular joint ends thereof. A passage extends through the subs. The female joint end and male joint end are rotationally coupled by ball bearings in the annular races. The replaceable sleeve is received in enlarged inner diameter portions of the male joint end and the female joint end. The first pressure seal ring is mounted between the replaceable sleeve and the enlarged diameter portion of the male joint end. The second pressure seal ring is mounted between the replaceable sleeve and the enlarged diameter portion of the female joint end.

A threaded connection partially in a self-locking arrangement includes a first and a second tubular component provided respectively with male and female threaded zone at their respective ends. Only a portion of a first portion with varying thread width of the male threaded zone cooperates by self-locking tightening with only a portion of the second portion with varying thread width of the female threaded zone when made up one into the other. The connection is able to withstand high torques required for special applications such as drilling with casing or intermediate casing.
