Sioux Chief 3/8" OD x 1/4" ID Milky Poly Tubing

Sioux Chief poly tubing is sized 3/8" OD x 1/4" ID and finished in a milky, translucent color typical of general-purpose polyethylene tube. It is built for rough-in plumbers and contractors who need a flexible, kink-resistant line for ice-maker, refrigerator, and supply-line connections behind cabinets, walls, and appliances. This poly tube ships in a 120 ft. coil, giving installers enough continuous length to run long appliance or fixture feeds without adding unnecessary joints, splices, or couplings mid-run. The flexible construction lets it snake through tight framing bays, cabinet toe-kicks, and appliance recesses where rigid pipe is impractical.

Key Features

  • Trade Size: 3/8" OD x 1/4" ID sizing fits standard compression-style connections commonly used on ice-maker valves and supply-stop fittings.
  • Polyethylene Construction: Flexible poly tubing resists kinking when routed through tight cabinet, wall, and appliance spaces, making it easier to pull through finished framing.
  • Milky Finish: Standard milky, translucent poly tube color used across general water-line rough-in work.
  • 120 ft. Coil: Long coil length reduces splices and fittings on extended ice-maker, refrigerator, and supply-line runs, cutting down on potential leak points.
  • Job-Site Ready: Coiled packaging pays off easily from the roll during rough-in and finish plumbing work, without the handling bulk of rigid pipe.
  • Field-Cuttable: Tube can be cut to length on site with standard tubing cutters, so installers carry one coil for multiple jobs instead of pre-cut lengths.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Ice-Maker and Refrigerator Water Line Connections
  • Supply-Stop and Fixture Feed Runs
  • Residential and Light Commercial Rough-In Plumbing
  • Behind-the-Wall and Under-Cabinet Tubing Routing
  • Renovation and New Construction Plumbing

Why Sioux Chief?

Sioux Chief is a long-standing name in rough-in plumbing supply, and this poly tubing carries the flexible, kink-resistant construction plumbers expect for ice-maker and supply-line connections. The 120 ft. coil format keeps installers stocked for multiple appliance and fixture hookups from a single roll, cutting down on splice fittings, extra trips to the supply house, and callbacks on the job site. For plumbers and contractors who need dependable, easy-to-route tubing for behind-the-wall and under-cabinet water line work, this Sioux Chief poly tube is a practical, job-site-ready choice.

Sioux Chief POLY – Frequently Asked Questions

1) Will 3/8 inch OD poly tubing work with the compression fitting on an ice maker valve?
Compression connections sized for 3/8 inch OD tube are what this Sioux Chief poly tubing is made for. The tube measures 3/8 inch OD with a 1/4 inch ID, which is the sizing used on ice-maker valves and supply-stop fittings. Match the fitting to the OD, not the ID, and use a sleeve/insert suited to poly tube so the ferrule does not crush the wall.
2) How long is the coil of Sioux Chief milky poly tubing?
It ships as a 120 ft. continuous coil. On a long refrigerator or fixture feed that means you can run the whole line off one roll with no mid-run couplings, and the leftover stays on the truck for the next hookup.
3) Can poly tubing be routed through tight framing and cabinet toe-kicks without kinking?
That is the point of it. The polyethylene wall is flexible and kink resistant, so it pulls through framing bays, toe-kicks, and appliance recesses where rigid copper would need fittings or would not make the bend at all. Keep bends sweeping rather than sharp and support the tube where it exits a cabinet.
4) What is this milky poly tubing actually made of, and where does it get used?
Polyethylene, in the standard milky translucent color used across general water-line rough-in. Typical uses are ice-maker and refrigerator water lines, supply-stop and fixture feed runs, and behind-the-wall or under-cabinet routing on residential and light commercial jobs.
5) Do I need special tools to cut this poly tubing on site?
No. The 120 ft. coil is cut to length in the field with a standard tubing cutter, so one roll covers several appliance or fixture hookups instead of carrying pre-cut lengths. Cut square so the ferrule seats evenly in the compression nut.
