摘要： A releasable push-to-connect tube fitting wherein a collet receiving the tube end is provided with longitudinally extending inner slots sized so as to limit constriction of the collet to maintain the outer diameter of the inner end of the collet greater than the minimum diameter of a confronting camming surface of a fitting body member for effectively positively retaining the collet in the body member upon assembly of the fitting elements. The collet includes an enlarged outer end exposed exteriorly of the fitting body for use in releasing the tube from the fitting when desired. The collet is retained in the body by constrictive deformation of the body outer end portion after installation of the collet therein. The constrictive deformation is effected by a suitable tool. In one embodiment, the fitting body is adapted to be secured in a port element. An eyelet may be provided for reception within the tube end to be connected to the fitting. The collet may be selectively provided with a plurality of tube biting teeth or a helical tooth.

摘要： A releasable push-to-connect tube fitting wherein a collet receiving the tube end is provided with longitudinally extending inner slots permitting constriction of the inner end of the collet about the tube end in the made-up condition of the fitting. The slots are sized so as to limit the constriction so as to maintain the outer diameter of the inner end of the collet greater than the minimum diameter of the confronting camming surface of the fitting body member, thereby effectively positively retaining the collet in the body member upon assembly of the fitting elements. The collet further includes an enlarged outer end exposed exteriorly of the fitting body in the made-up arrangement of the fitting for facilitated fingertip manipulation of the collet in releasing the tube from the fitting when desired. The collet is retained in the outer end of the body by constrictive deformation of the body outer end portion after installation of the inner portion of the collet therein. The constrictive deformation is effected by a suitable tool so as to define the desired inner surfaces of the body end cooperating with the collet in effecting the positive sealed connection of the tube end to the fitting.
摘要翻译：可释放的按压连接管配件，其中容纳管端的夹头设置有纵向延伸的内部狭槽，以允许在配件的组装状态下夹套的内端围绕管端收缩。狭槽的尺寸被设计成限制收缩，以便保持夹头的内端的外径大于装配体部件的相对的凸轮表面的最小直径，从而有效地将夹头牢固地保持在主体部件中在组装配件元件时。夹头还包括在装配件的组装布置中暴露在装配体外部的扩大的外端，用于在需要时使夹头从配件中释放出来的便于指尖操作。在将夹头的内部部分安装在其中之后，夹头通过主体外端部的缩小变形而保持在主体的外端。收缩变形由合适的工具实现，以便限定与筒夹配合的主体端部的期望的内表面，从而实现管端与配件的正密封连接。

摘要： A flareless tube fitting having a nose portion defining a sharp biting edge for sealingly retaining a tube end with a body member 11 of the fitting. Vibration forces acting on the tube end outwardly of the fitting are blocked from passing to the biting edge by a rounded support outwardly of the sleeve nose portion. The rounded support is formed by a tilting of a deflectible portion of the ferrule extending outwardly from the deformable ring portion and caused to be tilted so as to urge the ring portion radially inwardly into the tube end by the threaded advance of the nut member on the body member in the makeup of the fitting.

摘要： A tube connection having a resilient seal ring captured between a support structure at the inner end thereof and a retaining structure at the outer end thereof within an outwardly opening recess of a fitting body. The support structure is retained to the distal end of the tube to be connected against axially inward displacement therefrom. Close fits are provided between the elements of the fitting so as to effectively preclude extrusion of the seal material therebetween from the sealing space. The retaining structure in certain embodiments is defined by an annular projection on the nut member extending into the recess. In certain embodiments, the retaining structure is disposed outwardly of the recess and the sealing sleeve extends outwardly into engagement therewith. In one illustrated embodiment, the sealing sleeve is defined by an O-ring. In a number of the embodiments, the support structure is formed integrally with the tube end. Different combinations of the different structures is contemplated within the scope of the invention.

摘要： A tube bender construction for manual operation in bending a tube. The tube bender includes a mandrel defining a bending groove into which the tube is urged by a forming member mounted to the mandrel to swing about a bending axis of the bending groove. The tube to be bent is held against longitudinal movement during the bending operation by tube-holding structure arranged to clamp the tube against an extended groove portion of the mandrel. Movement of the forming member about the bending axis is effected by manipulation of a pair of handles which are arranged in offset manner to permit crossover of the handles and avoid interference between the user's hands thereon in the tube bending operation.

摘要： A manually operable tube flaring tool for providing a partial flare in the end of a deformable tube. The tool includes a flaring head defining an annular flaring surface and a cylindrical pilot portion projecting axially from the flaring surface to be received in the tube end for guiding the flaring surface axially against the distal end of the tube during the flaring operation. The tool further includes a support for fixedly positioning the tube end coaxially adjacent the flaring surface of the flaring head. The support defines an improved recess configuration providing a controlled buckling of the tube end by the forceful engagement therewith of the flaring surface wherein the buckled tube end defines preselected frustoconical inner and outer portions. The support may further define a conventional single flare recess opposite the partial flare recess whereby the tube may be used selectively to provide either of the partial or single flare flaring operations. The tube clamp may be defined by one leg of the U-shaped body and a cooperating clamp block movably carried by the body and adjustably positioned by a threaded member threaded through the other leg of the body.
