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

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.
