Swage tool
A swage mechanism operable to expand an inner diameter of tubing. The swage mechanism includes a housing defining a longitudinal axis, a plurality of jaws coupled to the housing and movable relative to the longitudinal axis for selectively gripping the tubing, and a ram including a cylindrical portion and a frusto-conical head portion. The frusto-conical head portion of the ram is insertable into the tubing to expand the inner diameter of the tubing.
Hydraulic tube expander and method of use
A hydraulic tube expander includes expanding jaws engageable with an interior surface of a tube to expand the tube; a source of hydraulic fluid, a valve located between the source and the expanding jaws and a single-action release actuator operatively coupled to the valve. The valve is moveable between open and closed positions. In the closed position, hydraulic fluid can pass from the source to the expanding jaws and in the open position the hydraulic fluid can pass from the expanding jaws to the source. The actuator is movable between first and second positions. In the first position the valve is in the closed position. Movement of the actuator in a direction from the first position toward the second position moves the valve into the open position.

Hand held flaring tool
A hand held flaring tool for flaring an end of a tube includes a body portion and a handle portion. The body portion receives the tube therein and includes a locking actuator operable to actuate a locking mechanism to secure the tube in the body portion. The body portion includes a flaring actuator operable to actuate a flaring mechanism to flare the end of the tube when the tube is secured in the body portion. The handle portion includes a grip portion that is grasped by a user's hand for supporting the body portion of the flaring tool during a flaring process of the tube. While the user is holding the handle portion to support the hand held flaring tool, the user is able to access and actuate first and second user inputs disposed at and accessible at the handle portion to actuate the locking actuator and flaring actuator.
PIPE ENLARGING DEVICE
A pipe enlarging device includes a base, an operation unit and a clamping unit. The clamping unit is received in the base and includes movable front, rear, left and right clamps, multiple resilient members and a front threaded rod. The front, rear, left and right clamps are resiliently movable when the front threaded rod is rotated so as to form an adjustable clamping area between the front, rear, left and right clamps. The clamping area is used to clamp pipes of different sizes. The operation unit includes a top threaded rod with a cone-shaped member which is used to enlarge the inner diameter of the pipes.

Mechanical spreader
A mechanical spreader along a spreading axis, characterized in that it comprises a support (1) and two spreading plates (2), each spreading plate (2) comprising at least one bevel (3), and in that it also comprises a central rod (4) able to slide in said support (1) between the two spreading plates (2), said central rod (4) comprising a plurality of bevels (5) having a profile complementary to the bevels (3) of said spreading plates (2), the bevels (5) of said central rod (4) being in contact with the bevels (3) of said spreading plates (2), said spreader also comprising return means able to exert a return force on the spreading plates (2), means for pushing the central rod (4) and means for immobilizing the spreading plates (2) in planes perpendicular to said spreading axis.
PEX EXPANSION TOOL
An expansion tool includes a working element configured to expand an end of a tube. The working element includes a plurality of jaws movable between a closed position and an expanded position. The expansion tool also includes first mandrel with a first contact surface and a second mandrel coupled to the first mandrel. The second mandrel has a second contact surface. The first mandrel and the second mandrel are movable together relative to the jaws between a retracted position and an extended position. The first contact surface and the second contact surface are engageable with the jaws to move the jaws from the closed position toward the expanded position in response to movement of the first mandrel and the second mandrel from the retracted position toward the extended position.
Flaring device for flaring the ends of pipes
A pipe flaring device is described. The device includes a main body extending along a mainly longitudinal direction. The main body also includes a flaring unit. The flaring unit interacts with an end of pipe to be flared. The main body also includes a die carrier arranged at the front of the flaring unit; and a flaring die. The flaring die includes a center channel which houses the pipe to be flared. The device includes a conical inner surface whose tapered end diverges towards the flaring unit and so that the inner surface matches a conical outer surface of the flaring die.
Apparatus and method for flaring a tube
An adjustable insertion-depth tube flaring tool is provided. A selector housing is disposed on a yoke. An adjustment nut is disposed within the selector housing. An adjustment screw is disposed within at least one of the selector housing and the yoke. A clutch housing has therein at least one biasing element, at least one lower clutch plate, and at least one upper clutch plate. An upper clutch plate rotation supporting element interacts with a lower clutch plate rotation supporting element to facilitate rotation of the upper clutch plate over the lower clutch plate in one direction. At least a portion of a shaft proximal end and an upper clutch plate inner wall are shaped to interact with one another in such a manner that the upper clutch plate is selectively prevented from rotating about the shaft proximal end when the upper clutch plate is disposed on the shaft proximal end.
