Abstract
A crimp ring removal tool for removing crimp rings from flexible tubing such as PEX. The tool is made from material of suitable hardness and comprises a collar block having at least one bore and ring slot pair to accommodate the dimensions of a flexible plumbing connection and a guide path to direct the operative portion of a common auxiliary cutting tool. The collar block is first secured in place against a plumbing connection with a clamping device such as locking pliers before the cutting tool is directed to interact with the crimp ring to be removed. Damage to the underlying plumbing fitting is spared or minimized because cutting is halted when penetration of the crimp ring is observed or halted by a stop.
Claims19
A tool for removing crimp rings from flexible plumbing connections which incorporate a rigid insert fitting within a flexible tubing end, the crimp ring removal tool comprising:
- a collar block, having a plumbing side and a cutting tool side, said collar block adapted for being easily indexed and securely held against the tubing and crimp ring of a flexible plumbing connection;
- a bore within the collar block forming at least part of a plumbing contact surface and corresponding in size to the outer circumference of the tubing;
- said bore having a centerline running parallel to the length of the bore;
- a ring slot adjacent to said bore and corresponding in size to the diameter of a crimp ring after it has been compressed over the tubing end;
- and
- a guide path communicating between the cutting tool side of the collar block and the bore;
- said guide path adapted for guiding the operative portion of an auxiliary cutting tool;
- whereby indexing the tool over a completed flexible plumbing connection positions the crimp ring within the ring slot of the collar block and exposes the crimp ring to the guide path for penetration by the operative portion of the auxiliary cutting tool.
A tool for removing a crimp ring from a flexible plumbing connection comprising:
- a collar block, having a plumbing side and a cutting tool side, said collar block adapted for being easily indexed and securely held against a flexible plumbing connection;
- at least one open bore, continuous with the plumbing side of the collar block, said bore having at least two points separated in distance to form a plumbing contact surface corresponding the outside circumference of a standard sized flexible plumbing connection;
- and
- one or more guide paths communicating between the cutting tool side of the collar block and the bore;
- said guide paths having cutting toll and plumbing ends and being adapted for guiding the operative portion of an auxiliary cutting tool;
- whereby indexing the removal tool over a completed flexible plumbing connection positions the crimp ring at the plumbing end of the guide path to be penetrated by the operative portion of the auxiliary cutting tool.
A tool for removing crimp rings from completed flexible plumbing connections comprising:
- a collar block having a first side and a second side, each of the sides having at least one plumbing contact surface;
- a first open bore and ring slot pair forming the plumbing contact surface of the first side;
- a first guide path communicating between the first open bore and ring slot pair and an opening on the second side, said first guide path adapted to direct an operative portion of a cutting tool into the first open bore and ring slot pair from the second side;
- a second open bore and ring slot pair forming the plumbing contact surface of the second side;
- and
- a second guide path communicating between the second open bore and ring slot pair and an opening in the first side, said second guide path adapted to direct an operative portion of a cutting tool into the second open bore and ring slot pair from the first side;
- said first open bore and ring slot pair and said second open bore and ring slot pair being oriented on the collar block in substantially opposite directions and adapted for indexing the tool against flexible plumbing connections such that crimp rings to be removed are held steady within the open bore and rings slot pairs while being acted upon by the operative portion of the cutting tool.
