Sioux Chief 305-999 Crimp Ring Removal Tool for 3/8" Through 1" PEX Pipe

The Sioux Chief 305-999 Crimp Ring Removal Tool is a rough-in plumber's tool built to free a copper crimp ring from a PEX fitting without wrecking the fitting's sealing surface. It is designed for use on brass or stainless steel fittings only and is suitable for 1/2" through 1" PEX pipe sizes, giving a plumber or contractor a fast way to reclaim fittings during rework, service calls, or callback repairs instead of cutting out and replacing the fitting entirely. The tool's cutting blade is engineered to penetrate only the copper ring and pipe, keeping the underlying brass or stainless fitting intact and reusable.

Key Features

  • Trade Size Range: Suitable for use on 1/2" through 1" PEX pipe sizes, covering the most common rough-in crimp connections.
  • Dual-Cut Design: Makes two cuts on the copper ring, allowing the installer to reclaim the fitting rather than discard it.
  • Fitting-Safe Cutting Blade: The cutting blade only penetrates the copper ring and pipe, allowing fitting recovery without damaging the sealing surfaces of the fitting.
  • Material Compatibility: For use on brass or stainless steel fittings only; do not use on copper or polymer fittings.
  • Jobsite Durability: Built as a dedicated rough-in hand tool for repeated crimp-ring removal tasks on service and repair calls.

Why Sioux Chief?

Sioux Chief designs this crimp ring removal tool specifically so plumbers can recover brass and stainless steel PEX fittings in the field rather than scrapping them after a bad crimp. By limiting the cutting blade's reach to the copper ring and pipe, the tool protects the sealing surfaces that make a fitting reusable, helping contractors save time and material costs on service and rough-in work. Note that this tool is not intended for use on copper or polymer fittings, so it should be reserved for its stated brass and stainless steel applications.

Sioux Chief 305-999 – Frequently Asked Questions

1) Can I use a crimp ring removal tool on poly (polymer) PEX fittings?
Not this one. The 305-999 is for brass or stainless steel fittings only. Sioux Chief specifically says not to use it on copper or polymer fittings, because the blade bears against the fitting body while it cuts the ring and a poly fitting will not survive that. If your rough-in used poly insert fittings, cut the connection out and replace the fitting.
2) Does removing the crimp ring with this tool ruin the PEX fitting, or can I reuse it?
The fitting is meant to be reused. The blade on the 305-999 penetrates only the copper ring and the PEX pipe, leaving the fitting's sealing surfaces (the barbs and shoulder) intact so a brass or stainless fitting can be re-crimped with a fresh ring and a new length of pipe. That is the whole point of the tool on a callback: recover the fitting instead of cutting it out.
3) How does a crimp ring removal tool actually get the copper ring off?
It makes two cuts in the copper ring. With the ring cut in two places it relaxes and comes off the fitting shank, rather than having to be ground or chiselled away. Both cuts stop at the ring and pipe, so the fitting underneath is not scored.
4) Is the Sioux Chief 305-999 for crimp rings or for stainless cinch clamps?
Crimp. The 305-999 is specified for crimp connections, meaning copper crimp rings over PEX, not stainless cinch (pinch) clamps. If you are removing cinch clamps you need a clamp removal tool instead.
5) Will the 305-999 remove a crimp ring on 3/8 inch PEX?
The tool's stated working range is 1/2 inch through 1 inch PEX. Work inside that band and you are within what Sioux Chief specifies for the 305-999.
6) What is the Sioux Chief part number for the PEX crimp ring removal tool, and how is it packaged?
The part is Sioux Chief 305-999, a single-model item with no size or finish options to pick. Case packaging is 40 each, and country of origin is China. Supply houses and MRO buyers standardizing a truck-stock list can order against that one number.
