The tool can be attached and easily operated without the disadvantage of having to apply physical strength in an awkward position. Different embodiments are provided that are adaptable to various valve body types. ## Claims ### Claim 1 A tool for rotating a nut adjacent to a valve body comprising: a valve body segment; a ferrule nut segment; and a threaded connecting bolt connecting the valve body segment and the ferrule nut segment approximately at respective distal ends, wherein the valve body has an inlet and an exit port offset by approximately 90 degrees, and wherein the nut is adjacent to the valve body inlet, wherein the valve body segment has a proximal end removably secured to the valve body, wherein the ferrule nut segment has a proximal end removably secured to the nut, and wherein the threaded connecting bolt is rotated in operation of the tool to improve a leverage in applying a torque to the nut. ### Claim 2 (depends on 1) The tool for rotating a nut adjacent to a valve body of claim 1, the ferrule nut segment further comprising: an aperture approximately at the distal end for receiving the threaded bolt; and a pin whereby the aperture is configured to rotate about the pin, wherein the aperture has an alignment defining an angle between the ferrule nut segment and the connecting bolt, wherein the pin allows for slight adjustment of the angle as the valve body segment and ferrule nut segment move closer together during tool operation. ### Claim 3 (depends on 1) The tool for rotating a nut adjacent to a valve body of claim 1, the ferrule nut segment further comprising: a slot in a handle portion thereof, the slot configured to receive the connection bolt; and a swivel having an aperture therein, the aperture and slot together configured to receive the connection bolt, wherein the swivel has a curved surface slidingly configured to an edge of the slot wherein thereby the swivel is configured to rotate with respect to the edge of the slot and further wherein thereby the swivel allows for slight adjustment of an angle between the ferrule nut segment and the connecting bolt as the valve body segment and ferrule nut segment move closer together during tool operation. ### Claim 4 (depends on 1) The tool for rotating a nut adjacent to a valve body of claim 1, the valve body segment further comprising a nut permanently affixed to a side of the valve body segment, the nut for receiving an the threaded connecting bolt, wherein the nut defines a fixed angle between the valve body segment and the threaded connecting bolt. ### Claim 5 (depends on 1) The tool for rotating a nut adjacent to a valve body of claim 1, wherein the valve body segment is secured around the valve body exit port. ### Claim 6 A tool for rotating a nut adjacent to a valve body comprising: a valve body segment; a ferrule nut segment; and a threaded connecting bolt connecting the valve body segment and the ferrule nut segment approximately at respective distal ends, wherein the valve body defines an three dimensional axis (x-y-z), wherein a z axis together with a y-axis together define an inlet and outlet port, respectively, wherein the valve body segment, the ferrule nut segment and connecting bolt lie substantially in an x-y plane, wherein the valve body segment has a proximal end removably secured to the valve body, wherein the ferrule nut segment has a proximal end removably secured to the nut, and wherein the threaded connecting bolt is rotated in operation of the tool to improve a leverage in applying a torque to the nut. ### Claim 7 A system for loosening a nut adjacent to a valve body comprising: a first wrench having a handle portion and a curved head for engaging the nut; a second wrench having a handle portion and an curved head for engaging the valve body; and a connecting bolt configured between the first wrench and the second wrench, wherein the first wrench comprises a slot through the handle portion to receive the connecting bolt. ### Claim 8 (depends on 7) The system for loosening a nut adjacent to a valve body of claim 7, further comprising: a rectangular nut housing coupled to the second wrench handle portion for receiving the connecting bolt; and a swivel having an aperture there through further for receiving the connecting bolt, the swivel having a curved surface and interfacing an edge of the slot. ### Claim 9 (depends on 8) The system for loosening a nut adjacent to a valve body of claim 8 wherein the edge of the slot has a curved surface for interfacing the swivel having a curved surface. ### Claim 10 (depends on 8) The system for loosening a nut adjacent to a valve body of claim 8 wherein the rectangular nut housing is offset by 45 degrees with respect the second wrench handle portion and the connecting bolt so that opposing edges of the housing are aligned to the bolt.
