Sioux Chief 664X PowerPEX Type-B Tubing, 3/4" CTS

The Sioux Chief 664X is PowerPEX Type-B tubing in 3/4" CTS size, supplied in color-coded 20 foot lengths, 25 lengths per bag (500 ft per bag), for rough-in water distribution piping. This tubing line is available in Blue or Red color coding, giving crews the ability to visually distinguish cold-water and hot-water supply runs during rough-in and inspection while using the same tubing construction and specifications across both colors. The 664X is compatible with ASTM F1807/F2159/F1960/F3347 and ASSE 1061 fitting systems, giving plumbers flexibility to transition between crimp, cinch, and expansion-style PEX connections on the same jobsite without switching tubing products.

Key Features

  • Trade Size: 3/4" CTS tubing sized for residential and light commercial water distribution branch lines.
  • Put-Up: Supplied in 20 foot lengths, packed 25 lengths per bag for a total of 500 ft per bag, reducing coil memory and easing installation runs compared to long coils.
  • Color-Coded Construction: Available in Blue or Red PEX tubing for quick visual identification of cold-water and hot-water supply lines during rough-in, with both colors sharing the same tubing construction and ratings.
  • Multi-System Compatibility: Works with ASTM F1807, F2159, F1960, and F3347 fitting systems, giving installers a choice of crimp, cinch, or expansion connection methods.
  • ASSE 1061 Compliant Fitting Compatibility: Suitable for use with fitting systems meeting ASSE 1061 for PEX tube fittings.
  • Expansion Joint Guidance: Sioux Chief recommends that all F1960 expansion joints made with PowerPEX Type-B tubing be formed using a self-rotating, power expansion tool for consistent, reliable joints.
  • Water Distribution Use: Ideally suited for potable water distribution piping in rough-in plumbing systems.

Sioux Chief 664X3B20 – Frequently Asked Questions

1) Can I use crimp rings on Sioux Chief 664X PowerPEX tubing, or does it require an expansion tool?
The 664X works with ASTM F1807 (copper crimp), F2159 (poly insert crimp), F1960 (cold expansion) and F3347 fitting systems, so crimp, cinch, or expansion connections are all on the table with the same tubing. One caveat from Sioux Chief: F1960 expansion joints made with PowerPEX Type-B should be formed with a self-rotating power expansion tool, not a manual expander, for consistent joints.
2) Is Sioux Chief 664X PEX sold in coils or straight lengths?
Straight lengths. The 664X comes as 20 foot sticks, 25 per bag, which is 500 feet per bag. Straight lengths avoid the coil memory you fight with long rolls, which matters on open-joist rough-in runs where you want the tube to lie flat.
3) What is the difference between the blue and red Sioux Chief 664X tubing?
Color only. Blue (MPN 664X3B20) and red (664X3R20) share the same tubing construction and specifications; the color coding is there so crews and inspectors can tell cold from hot at a glance during rough-in.
4) Is 3/4 inch PEX the right size for a main branch run to fixtures?
The 664X is 3/4 inch CTS, which is the usual size for water distribution branch lines feeding groups of fixtures in residential and light commercial work, with smaller sizes dropped off it at individual fixtures. CTS means copper tube size, so it is sized to the same nominal convention as the copper it typically replaces on a repipe.
5) Is this PEX made in the USA for a government or institutional spec job?
Yes. Country of origin on the 664X PowerPEX tubing is the United States, which is what domestic-preference procurement specs ask for on piping material.
6) How many feet of 3/4 inch PEX do I get per bag, and how do I figure quantity for a repipe?
Each bag of 664X holds 500 feet, made up of 25 pieces at 20 feet each. Because it ships as sticks rather than a continuous coil, take off your longest single run first: any run over 20 feet needs a coupling, so count joints as well as footage when you order fittings alongside the tube.
