Sioux Chief 305-7120 1/2" Compact PEX Crimp Tool with Carrying Case

The Sioux Chief 305-7120 is a 1/2" compact crimp tool built for installing PEX crimp rings on PEX tubing and fittings, and it also works on PB F1380 tube and fittings. Sized for one-hand crimping in tight rough-in spaces, this tool ships with a carrying case for jobsite transport and storage, plus a Go/No-Go gauge for verifying every crimp connection meets spec. It's a practical rough-in tool for plumbers running PEX supply lines behind walls, under floors, and in mechanical rooms where standard full-size crimp tools don't fit.

Key Features

  • Trade Size: Sized for 1/2" PEX crimp rings and connections.
  • Compact Design: Allows for one-hand crimping, making it easier to work in cramped behind-the-wall and under-floor installations where a full-size tool can't maneuver.
  • Dual Tubing Compatibility: Works on standard PEX connections as well as PB F1380 tube and fittings, giving plumbers one tool for two tubing systems.
  • Go/No-Go Gauge Included: Every tool ships with a Go/No-Go gauge so crimp rings can be checked and verified on the spot without a separate purchase.
  • Carrying Case: Includes a dedicated case for safe transport, storage, and organization in a service vehicle or tool bag.

Technical Specifications

  • Trade Size: 1/2"
  • Country of Origin: China
  • Packaging: 8 EA per case

Typical Applications

  • Residential and Commercial PEX Rough-In Plumbing
  • PB (Polybutylene) Tube and Fitting Repair or Replacement
  • Tight-Access Crimping in Walls, Floors, and Mechanical Rooms
  • Service Truck and Field Repair Kits

Why Sioux Chief?

Sioux Chief builds this compact 1/2" crimp tool with a one-hand grip for plumbers who need reliable PEX and PB crimp connections in spaces a full-size tool can't reach. The included Go/No-Go gauge lets installers confirm every crimp on the spot, and the carrying case keeps the tool and gauge organized and ready for the next job.

Sioux Chief 305-7120 – Frequently Asked Questions

1) Will a PEX crimp tool work on old polybutylene tubing?
This one will. The Sioux Chief 305-7120 is rated for standard PEX crimp connections and for PB F1380 tube and fittings, so a service tech doing polybutylene repair or partial replacement can carry one tool for both systems instead of two.
2) Can I crimp in a tight stud bay or under a floor with this tool?
That's what it's built for. The 305-7120 is a compact, one-hand crimping tool, so it fits into stud bays, crawl spaces and mechanical room corners where a full-size two-hand crimper can't be squared up on the ring.
3) Do I need to buy a Go/No-Go gauge separately for this crimp tool?
No. A Go/No-Go gauge ships with the Sioux Chief 305-7120, so you can verify each 1/2 inch crimp ring on the spot. That matters on inspected work, where the gauge check is how you prove the connection is in spec before the wall closes up.
4) Is a crimp tool the right choice, or should I use a press or expansion tool for PEX?
The 305-7120 is a crimp-ring tool: it compresses a copper crimp ring over PEX on a barbed insert fitting, which is the common method for PEX-A and PEX-B supply lines and the system most residential rough-in uses. It will not work with cold-expansion fittings or with press/crimp sleeve systems that use their own jaws. If your fittings call for expansion rings or a press jaw, this is the wrong tool; if you're buying copper crimp rings, it's the right one.
5) Does the Sioux Chief 305-7120 come with a case?
Yes, a carrying case is included for the tool and gauge, which is the practical difference for a service truck or a stocked repair kit. Nothing else is needed to make a crimp connection beyond the PEX tubing, fittings and 1/2 inch copper crimp rings, which are bought separately.
6) How do I order the compact Sioux Chief PEX crimp tool, and how is it packed?
Order it as Sioux Chief part number 305-7120. It's a single configuration tool, 1/2 inch, with no finish or size options to specify. Case quantity is 8 each per case for anyone stocking tools across multiple trucks or a supply room.
