An anti-rotation device for preventing a hydraulic connector assembly from leaking. Various embodiments of the anti-rotation device provide a mechanism whereby threadably engaged connectors, such as compression fittings, are permitted to rotate only a fraction of a turn after loosening. For many applications, the limited degree of loosening is sufficient to prevent the onset of leaking. Structurally, the anti-rotation device can include a band that is secured to a female nut of a hydraulic connector. Protrusions extend laterally from the band and engage with a stop tab on the male body of the hydraulic connector assembly, thereby limiting rotation of the female nut that would otherwise cause leaks.

A pipe connecting device configured to connect at least two pipes, comprises a pipe including a catching ledge at a connecting end portion thereof and made of stainless steel or copper; a first connecting member formed in a cylindrical shape and having a spring seating portion on which a circular plate spring is seated, a pipe through-hole through which the pipe passes, and a screw recess provided inside the first connecting member; and a second connecting member provided with an o-ring seating portion on which an o-ring is seated at a side at which the pipe is coupled and an outer surface having a screw thread, wherein a through-portion having the same inner diameter as the pipe is formed in the second connecting member.

A withdrawal system (1) for a container (2) and comprises an immersion pipe (4) mounted on and projecting into the container (2) as well as a withdrawal head (5) that is attachable to the immersion pipe (4) by means of a rotary connection. The withdrawal head (5) attached to the immersion pipe (4) is secured by means of a mechanical locking unit.

A connector has five or six abutment surfaces for cable ducts. The cable ducts may have substantially square end faces or rectangular end faces half as large. The connector has a main body made of metal, which exhibits one or two square abutment surfaces or portions thereof, and which exhibits four smaller substantially rectangular abutment surfaces.

An aircraft pipe coupling includes a first pipe end and a second pipe end connected to each other by a fastener. A locking collar restricts the rotational movement of the first pipe end, the second pipe end, and the fastener with respect to one another. The locking collar includes a first engagement portion and a second engagement portion, one of the engagement portions includes a resiliently deformable engagement surface. The first engagement portion is located over and engaged with the fastener, and the second engagement portion is located over and engaged with the second pipe end.

The present invention relates to a pipe fitting apparatus providing easy locking with an appropriate torque, and more specifically, relates to a pipe fitting apparatus providing easy locking with an appropriate torque for which the possibility of breakage and leakage has been eliminated by being easily configured in a manner that the locking of the pipe fitting apparatus used to connect pipes is performed with an appropriate torque. The pipe fitting apparatus has a fitting body, a force control ferrule, and a fixing nut. The fitting body has a first connecting portion with an inner threaded surface, a second connecting portion having an outer threaded portion, and a ferrule seating portion where the force control ferrule is provided. The fixing nut has an inner threaded portion for engaging with the second connecting portion of the fitting body and an inclined pressure surface for abutting against the force control ferrule.

A tube fitting includes a fitting body, a first coupling member configured to surround the fitting body, a fitting nut coupled to the fitting body, and a second coupling member provided on the fitting nut, wherein the first coupling member includes first coupling protrusions, and the second coupling member includes second coupling protrusions coming in contact with the first coupling protrusions while the fitting body and the fitting nut are coupled.
