Sioux Chief 664X4R20 – Frequently Asked Questions
1) Can I use crimp rings on Sioux Chief 664X4R20 1 inch PEX, or does it require expansion fittings?
Both work. The 664X4R20 PowerPEX tubing is compatible with ASTM F1807 (copper crimp), F2159 (poly insert), F1960 (cold expansion) and F3347 fitting systems, plus ASSE 1061-listed push fittings. So you can crimp, cinch, or expand depending on what the job spec calls for. One caveat from Sioux Chief: F1960 expansion joints on PowerPEX Type-B tubing should be formed with a self-rotating power expansion tool, not a manual tool, for consistent joints.
2) Do I need a special expansion tool for 1 inch PowerPEX expansion joints?
For F1960 cold-expansion connections on PowerPEX Type-B tubing, Sioux Chief recommends forming the joint with a self-rotating, power expansion tool. At 1 inch, a manual expander is hard work and inconsistent anyway. If you would rather not buy or rent the power tool, specify an F1807 copper crimp or F2159 fitting system instead, both of which this tubing accepts.
3) Is red PEX tubing only for hot water, or can I run it cold?
Red is a trade color convention, not a material difference. On the Sioux Chief 664X4R20, the red jacket marks the tubing as hot-side water distribution so anyone opening the wall later can identify the run at a glance. The tubing itself is PEX for water distribution; the color is for identification. Most crews order red for hot and blue for cold and keep it consistent through the building.
4) How much 1 inch red PEX comes in a bag of Sioux Chief 664X4R20?
One bag holds 15 straight 20-foot lengths, 300 feet total. That is the ordering unit: 1 BG. Straight lengths rather than a coil, so you are not fighting coil memory on long horizontal mains, but you do need the truck space and a path to carry 20-foot sticks into the building.
5) Should I use 20-foot straight lengths or coiled PEX for a water distribution main?
Straight lengths like the 664X4R20 1 inch PowerPEX suit long, mostly linear runs: trunk mains, horizontal distribution above ceilings, and repipe work where you want fewer couplings over the length. Each 20-foot stick covers more distance per joint and lies flat with no coil memory to fight. Coils make more sense for branch runs that snake through joists and studs with lots of direction changes. For a 1 inch hot main feeding manifolds or branch takeoffs, the 20-foot sticks are the usual pick.
6) Is Sioux Chief PowerPEX made in the USA? I have a domestic sourcing requirement on the job.
Yes. The 664X4R20 PowerPEX tubing is manufactured in the United States, which matters on public and institutional work carrying domestic material provisions. Country of origin is listed as United States.
7) Does Sioux Chief 664X4R20 meet ASTM F1807 for crimp fittings?
ASTM F1807 is listed as a standard for this tubing, so copper crimp ring fittings made to F1807 are a valid connection method on the 664X4R20. The tubing is also stated as compatible with F2159, F1960, F3347 and ASSE 1061-listed fittings.
