摘要： A split coupler, and methods of making and using such a split coupler, whereby the split coupler includes a first semi-cylindrical member, a second semi-cylindrical member, and an interlocking assembly configured to interlock the first and second semi-cylindrical members to form a substantially cylindrical coupler having a coupler inner surface which defines a throughbore. Additionally, the split coupler can include spiral threads coupled to the coupler inner surface. Furthermore, the split coupler can include a flange inwardly extending from the coupler inner surface.

摘要： A pipe-fitting device according to the present invention includes a fitting body, a fixing nut, and a collet. A first end of the fitting body is rotatably connected to an outer circumferential surface of a first pipe, and a second end of the fitting body surrounds an outer surface of a second pipe. A first end of the fixing nut is rotatably connected to an outer circumferential surface of the fitting body, and a second end of the fixing nut surrounds the outer surface of the second pipe. The collet is provided inside the fixing nut and presses the second pipe when the fixing nut is rotated and tightened. The collet includes a seating portion provided inside the fixing nut, a bending portion in which a bending groove is formed, a pressing portion which presses and seals the second pipe, and a protecting portion which protects the pressing portion.

摘要： A tube fitting device for facilitating tube connection position determination includes a fitting body, a pair of fixing nuts, and an O-ring. The fitting body has a cylindrical channel portion into which a first tube and a second tube may be inserted, the cylindrical channel portion comprising an accommodation groove formed therein. Each fixing nut is rotatably coupled to a respective open end of the fitting body and surrounds the first tube and the second tube, respectively. The O-ring is mounted on the accommodation groove and has an inner diameter smaller than that of the cylindrical channel portion such that the inner surface of the O-ring protrudes inside the fitting body to facilitate determining positions of the first tube and the second tube to be inserted into the cylindrical channel of the fitting body.

摘要： 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).
