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

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.

• 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.

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.
