A release clip for a tube connector is provided for use in a system with flowing fluid. The tube connector includes a housing with an opening through which the flowing fluid passes, and is arranged for secure and sealing connection with a tube which is inserted in the connector. In the housing there is mounted a circular gripper ring which grips the tube. The release clip has a tubular circular release body which is split along its longitudinal axis and includes an integral hinge, thus enabling it to be mounted around the tube that has to be released and the length of the release body in its longitudinal direction is at least equal to the distance extending from the housing's opening to the gripper ring.

An example tool includes a housing; an inclined handle coupled to, and extending obliquely from, a top portion of the housing, where the inclined handle has a first trigger button and a second trigger button; and an interlocking mechanism disposed in the inclined handle. The interlocking mechanism is configured to disable one of the first trigger button or the second trigger button while the other of the first trigger button or the second trigger button is triggered.

A tool head includes a first frame having a first arm and a second arm extending from a base to a distal end. The tool head may also include a first blade in the frame between the first arm and the second arm. The first blade is movable from the base toward the distal end. The tool head further includes a second frame hingedly coupled to the first arm. The second frame may include a second blade. The second frame is configured to rotate between a closed-frame position and an open-frame position. The tool head further includes a trip lever hingedly coupled to the first arm and configured to rotate between an open-lever position and a closed-lever position. The trip lever is in the open-lever position when the second frame is in the closed-frame position and the trip lever is in the closed-lever position when the second frame is in the open-frame position.

An example tool includes a hydraulic actuator cylinder; a piston slidably accommodated within the hydraulic actuator cylinder, where the piston includes a piston head and a piston rod extending from the piston head along a central axis direction of the hydraulic actuator cylinder, the piston head divides an inside of the hydraulic actuator cylinder into a first chamber and a second chamber, and the piston rod is disposed in the first chamber and configured to move one or more jaws of the tool; a pump configured to provide pressurized fluid; and a sequence valve configured to block the pressurized fluid from flowing into the second chamber of the hydraulic actuator cylinder until pressure of the pressurized fluid exceeds a threshold pressure value.

A tube fitting for sealing an end of a tube uses a notch formed in the exterior surface of the tube as a sealing seat. An internally threaded body is configured to receive an externally threaded end of a nut, while the body and the nut are mounted in a surrounding relationship to the tube end. A ferrule mounted between the nut and the tube is forced to plastically deform and move into the notch to thereby seal the tube end.

Hydraulic tool for driving a pulling and/or pressing device, comprising a drive shaft that can be mounted to a screwdriver, wherein the drive shaft is operable to drive a hydraulic pump that pumps hydraulic fluid into the operating chamber of a hydraulic power piston. The hydraulic tool may in particular be configured as a riveting or punching attachment for a cordless screwdriver.

A die set for crimping operations includes first and second die members having raised areas including a plurality of knurls and character areas. The die set combining knurls and character areas on the operative areas of the die members allows a single die set to be used to condition a surface for crimping operations as well as crimping connectors and marking them with relevant indicia without having to change die sets.

A power tool includes an outer housing having a drive unit support portion and a handle portion, an inner housing positioned at least partially within the handle, and a drive unit positioned in the drive unit support portion. The drive unit includes an output shaft extending at least partially through the handle portion. The power tool also includes a ball screw mechanism having a nut supported at least partially within the inner housing and a screw coupled to the nut for relative axial displacement therewith in response to relative rotation between the screw and the nut. Torque from the output shaft is applied to one of the nut and the screw to cause the relative rotation. The handle portion exerts a reaction torque on the inner housing in response to the relative rotation between the nut and screw to prevent the inner housing from rotating relative to the outer housing.
