Sioux Chief 305-649 Cinch Clamp Crimp Tool, 3/8" - 1"

The Sioux Chief 305-649 is a cinch clamp crimp tool built for installing cinch-style stainless steel clamps onto PEX tubing connections ranging from 3/8" to 1". This hand tool compresses the clamp band evenly around the PEX fitting to create a secure, properly seated connection for rough-in and remodel plumbing work. It gives plumbers and contractors a single dedicated tool for every cinch clamp size in that range instead of switching tools mid-job. It is manufactured in China and supplied 10 EA per pack for stocking distributors and plumbing contractors.

Key Features

  • Trade Size Range: Handles cinch clamp installations from 3/8" up to 1" on PEX tubing connections, covering the sizes most common in residential and light commercial rough-in.
  • Tool Type: Purpose-built cinch clamp crimp tool for compressing stainless steel cinch clamps onto PEX fittings during rough-in and repair work.
  • Connection Method: Designed specifically for cinch-style crimp connections, the clamp method commonly used alongside standard crimp rings in PEX rough-in plumbing.
  • One-Handed Operation: Hand-operated design lets a plumber crimp cinch clamps directly at the fitting without a separate powered tool, useful in tight wall or ceiling cavities.
  • Jobsite Durability: Built as a dedicated trade tool intended for repeated use across multiple PEX connections on a job rather than single-use disposable hardware.
  • Packaging: Supplied 10 EA per pack for distributor and jobsite stocking.

Why Sioux Chief?

Sioux Chief supplies rough-in plumbing hardware used by professional contractors, and the 305-649 crimp tool is built to install cinch clamps consistently across the full 3/8" to 1" PEX size range. A dedicated crimp tool like this helps plumbers seat each cinch clamp connection properly on every PEX joint during rough-in work, rather than relying on general-purpose pliers that can under- or over-compress the clamp band. Stocking it alongside Sioux Chief cinch clamps and PEX fittings gives distributors and contractors a matched, single-source rough-in solution for the job.

Sioux Chief 305-649 – Frequently Asked Questions

1) Will a cinch clamp tool work on copper crimp rings for PEX?
No. The Sioux Chief 305-649 is built for cinch-style clamp bands, which have a raised ear that gets pinched closed. Copper or brass crimp rings are compressed uniformly around their full circumference and need a ring crimper with matching jaws for each size. If your fittings were installed with copper rings, this tool is the wrong one for the joint.
2) Can I use pliers instead of a dedicated cinch clamp tool on PEX?
General-purpose pliers can under- or over-compress the clamp band, which is where leaks start. The 305-649 is jaw-shaped to pinch the clamp ear down consistently on every joint across the 3/8 to 1 inch range, so each connection seats the same way. For rough-in work behind drywall, that consistency is the whole point.
3) Does this Sioux Chief crimp tool work one-handed in a tight wall cavity?
It's a hand-operated tool, no power unit or hose, so you can take it into a joist bay or ceiling cavity and crimp right at the fitting. That matters on remodel work where you're reaching into an open wall section rather than working on a bench.
4) How many Sioux Chief 305-649 crimp tools come in a pack?
They ship 10 each per pack, which is a distributor and multi-crew stocking quantity rather than a single tool off the shelf. Plumbing contractors outfitting several trucks order it this way so every van carries the same cinch tool.
5) Is the Sioux Chief 305-649 the right tool for repairing an existing cinch clamp joint?
Yes, for redoing the connection. Cinch clamps are cut off, not reopened, so a repair means removing the old clamp, sliding a new one on and pinching it with the 305-649. The tool covers 3/8 through 1 inch, so it handles retrofit and repair work on any of the common PEX branch and trunk sizes.
