Disclosed is a quick-disassembly nipple connector structure, which is mainly composed of a hollow pipe, a pivoting assembly, a screwing member, a plurality of gripping jaws, a sleeve, a handle and a spring. The handle is additionally disposed on the sleeve and the pivoting assembly; when the handle is not pulled, the sleeve is located at a lock position to lock a grease nipple; and when the handle is pulled downwards, the sleeve is located at a release position to release the grease nipple. The quick-disassembly nipple connector structure can be rapidly switched to the lock position or the release position, thus, facilitating operation, shortening the work time, achieving accurate alignment, improving work efficiency, and avoiding damage to internal parts caused by excessive force application by users.

Disclosed is a quick-disassembly nipple connector structure, which is mainly composed of a pipe, a pivoting assembly, a screwing member, a plurality of gripping jaws, a sleeve and a handle. The handle can be pulled by users to enable the quick-disassembly nipple connector structure to be rapidly connected to or separated from a grease nipple. When the handle is pulled downwards, the sleeve is located at a lock position to lock the grease nipple; and when the handle is pulled upwards, the sleeve is located at a release position to release the grease nipple. Thus, the quick-disassembly nipple connector structure has the advantages of being capable of improving work efficiency, high in positioning speed, high in accuracy and good in fixing property and has a good overall constituent strength, so that the motion stability is improved, and the operation smoothness and service life are ensured.

A self-tightening sealing connector includes a first tubular member, a second tubular member, a first locking member, and a first sealing member. The first tubular member includes a first connecting end and a first flange located at the first connecting end. The second tubular member includes a second connecting end. The second connecting end is configured to be connected with the first connecting end thereby fluid communicating the first tubular member with the second tubular member. The first sealing member is configured to be located between the first locking member and the first flange. In an assembled state, the first locking member and the first flange are capable of applying a force on the first sealing member in an axial direction, and the force can be increased, when an inner fluid pressure is increased.

A double containment fitting for connection to a double containment tubing system with an outer, secondary containment tubing surrounding an inner, primary tubing. The fitting includes a fitting body defining a central passageway, the fitting body having a center portion disposed between opposed first and second body ports. The fitting body is configured to receive the tubing system into the first body port. The central passageway has a diameter in the first port selected to allow the secondary tubing into the first body port. A connection system mechanically secures the secondary tubing to the first body port.
