Sioux Chief 305-999 Crimp Ring Removal Tool 3/8 to 1 Inch

Product Description

The SIOUX CHIEF 305-999 is a crimp ring removal tool designed to cut and remove stainless steel and copper crimp rings from PEX tubing connections without damaging the tubing itself. It handles a full range of residential and light commercial PEX fitting sizes, from 3/8 inch through 1 inch. Licensed plumbers and pipefitters use this tool when decapping fittings during repairs or system modifications where the PEX line needs to be salvaged and reused. The 305-999 simplifies a task that otherwise risks scoring or kinking the tubing when done with general-purpose cutters.

This tool is suited for plumbing service work involving PEX-A, PEX-B, and PEX-C tubing systems where crimp-style connections are present. Typical use cases include repair calls on residential water supply lines, radiant heating systems, and manifold-based distribution systems. It is most commonly reached for when a fitting has been crimped incorrectly, a ring has been installed on the wrong size fitting, or an existing connection must be broken to extend or reroute a line.

Key Features

• Removes crimp rings across the full 3/8 inch through 1 inch PEX size range
• Designed to cut rings cleanly without scoring or kinking the underlying PEX tubing
• Compatible with both copper and stainless steel crimp rings
• Supports repair and rework tasks without requiring the tubing to be cut out entirely

Compatibility

Designed for use with copper and stainless steel crimp rings on PEX tubing sized 3/8 inch through 1 inch, consistent with standard residential and light commercial plumbing crimp-style fittings.

Installation Notes

Shut off water supply and depressurize the line before removing any crimp ring. A licensed plumber should confirm the fitting condition and tubing integrity after ring removal before recrimping or installing a new fitting. Follow all applicable local plumbing codes, including IPC guidelines, when modifying or repairing PEX systems. Inspect the tubing end for deformation or damage before reusing it with a new crimp ring and fitting.
