A portable pipe threader includes a housing, a carriage, and at least one pipe threading tool. A drive assembly of the is at least partially positioned within the housing and includes an electric motor operable to provide torque to the pipe. A lubrication system is removably coupled to the housing and includes a reservoir for holding a lubricant and a pump powered by the drive assembly. A stand of the portable pipe threader is adjustable between collapsed and deployed states. When collapsed, a longitudinal axis of the housing is maintained at a first oblique angle relative to a horizontal reference plane parallel with a work surface upon which the stand is supported to funnel lubricant toward the reservoir. When deployed, the longitudinal axis is maintained at a second oblique angle to funnel lubricant away from an end of the pipe on which a working operation is performed.

A fish tape tool includes a housing including a base and a cover. The housing defines a chamber between the base and the cover. The base defines an exit opening and a channel extending from the chamber to the exit opening. The fish tape tool also includes a drum configured to be inserted into the chamber of the housing, the drum containing a fish tape. The drum is configured to be manually rotatable relative to the housing to dispense or retract the fish tape from the housing via the channel and the exit opening. The cover defines a central aperture that is aligned with a central bore of the drum.

Fish tape assembly

A fish tape assembly includes a fish tape tool including a housing, a chamber defined in the housing and a motor supported by the housing. The fish tape assembly also includes a fish tape drum configured to be inserted into the chamber of the housing. The fish tape drum contains a type of fish tape and includes a rotatable drum portion configured to rotate in response to receiving torque from the motor. The fish tape tool includes a sensor configured to detect the type of fish tape in the fish tape drum inserted into the chamber of the housing.

A system attachable to a refrigeration circuit includes a recovery pump attachable to the refrigeration circuit to remove refrigerant. The recovery pump includes a pump, an electric motor, a battery pack, and a recovery pump controller for controlling the operation of the electric motor. The recovery pump controller has a first communication interface. The system further includes an accessory attachable to the refrigeration circuit concurrently with the recovery pump. The accessory includes a sensor for detecting a characteristic value of the refrigeration circuit, and an accessory controller electrically connected with the sensor to receive a signal corresponding with the characteristic value of the refrigeration circuit. The accessory controller has a second communication interface to communicate the signal to the recovery pump controller via the first and second wireless interfaces. The recovery pump controller controls the operation of the electric motor based upon the signal received from the accessory.

System including recovery pump and vacuum pump

A fish tape drum includes a frame and a drum portion rotatable relative to the frame. The drum portion has an outer wall and an inner wall. The first tape drum also includes a length of fish tape arranged between the inner wall and the outer wall. The fish tape drum further includes a constricting assembly configured to bias the length of fish tape toward the inner wall.

A portable pipe threader includes a stand upon which a pipe is supported, a carriage supported by the stand upon which at least one pipe threading tool is supported, a spindle including a plurality of chuck jaws for clamping the pipe, the chuck jaws configured to move radially inward along a travel path toward an outer surface of the pipe, and a sensor system configured to determine a location of the chuck jaws along the travel path and relative to the outer surface of the pipe, the sensor system configured to output a signal corresponding to the location of each of the chuck jaws when engaged with the outer surface of the pipe. The portable pipe threader further includes an electronic controller in communication with the sensor system configured to determine an outer diameter of the pipe in response to the signal output from the sensor system.

A power tool is provided that can include a body, a battery pack interface coupled to the body, an electronic controller coupled to the body, and a sled configured to engage with the battery pack interface. The sled can include a battery, and a boost converter electrically connected to the battery. An output of the boost converter can be configured to be electrically connected to the battery pack interface to provide a boosted voltage to the power tool.

A portable pipe threader includes a stand upon which a pipe is supported, a carriage supported by the stand, and a plurality of pipe threading tools coupled to the carriage and selectively operable to perform work on the pipe. The portable pipe threader further includes a drive assembly mounted to the stand including a brushless direct current ('DC') motor operable to provide torque to one of the pipe or a selected one of the pipe threading tools to rotate the pipe and the selected one of the pipe threading tools relative to each other, and a battery pack supported by the stand in selective electrical communication with the motor to provide electrical power to the motor.

A fish tape tool includes a housing, a chamber defined in the housing, and a motor supported by the housing. The motor is configured to rotate in a first direction and a second direction that is opposite the first direction. An output reel is disposed in the chamber and is rotatable in response to receiving torque from the motor. A drum contains a fish tape and including a rotatable drum portion having an inner wall that is engaged by the output reel when the drum is inserted into the chamber of the housing. When the drum portion is rotated by the output reel in the first direction, fish tape is dispensed from the drum. When the drum portion is rotated by the output reel in the second direction, fish tape is retracted into the drum.

A fish tape tool includes a housing and a chamber defined in the housing. A drum is configured to be inserted into the chamber of the housing. The drum contains a fish tape. The drum is rotatable relative to the housing to dispense or retract the fish tape from the housing. The drum is one of a plurality of drums that are insertable into and removable from the chamber of the housing. Each drum contains a different type of fish tape.
