Sioux Chief 641WG No-Lead Brass PEX Tee

The Sioux Chief 641WG Series is a one-piece no-lead brass PEX tee built for F1960 expansion-style PEX connections in behind-the-wall rough-in plumbing. This fitting line is available in 1/2" and 3/4" sizes, giving plumbers and contractors a branch-takeoff option for a range of PEX distribution runs. The one-piece no-lead brass body eliminates the need for secondary crimp rings at the fitting itself and is manufactured in the United States, giving installers a domestically produced, code-oriented option for potable water rough-in work. Across the 641WG Series, the shared design delivers full flow with no internal restriction, so plumbers get consistent performance whether they're selecting the 1/2" or 3/4" version for a given branch run.

Manufactured in the United States, this PEX tee line gives contractors a dependable, code-oriented component for F1960 expansion connections on rough-in jobs where consistent flow and durable brass construction matter, no matter which size the job calls for.

Sioux Chief 641WG442 – Frequently Asked Questions

1) What sizes does the Sioux Chief 641WG brass PEX tee come in?
Two sizes, 1/2 inch and 3/4 inch, ordered as 641WG442 for the 1/2 inch and 641WG443 for the 3/4 inch. Both are straight tees with all three outlets the same size, so a 3/4 inch main with a 1/2 inch branch takeoff needs a reducing tee rather than either of these.
2) What else do I need to install the 641WG PEX tee?
PEX-a tubing rated for F1960, F1960 expansion rings in the matching size, and an expander tool with the correct head for 1/2 or 3/4 inch. No crimp rings are used at the fitting itself. Order the ring size to match the tee, 1/2 inch rings for 641WG442 and 3/4 inch for 641WG443.
3) Is the 641WG tee approved for potable drinking water lines?
The 641WG is a no-lead brass fitting intended for potable water distribution, which is what the no-lead designation covers for domestic water rough-in. One-piece brass body, so there is no secondary joint inside the fitting to seal or to corrode at.
4) Does this PEX tee meet a Made in America or domestic sourcing requirement on a plumbing bid?
Country of origin on the 641WG tee is the United States, so it fits bids and specs that call for domestically manufactured plumbing components. Confirm the exact clause your spec cites, since domestic-content rules differ by program.
5) Will a brass expansion tee restrict flow on a PEX branch run?
No. The 641WG body is full flow with no internal restriction, so the branch tee does not step the waterway down the way some insert-style fittings do. Insert fittings for crimp systems sit inside the tubing ID and shrink the waterway at every joint; an F1960 expansion fitting goes inside an expanded tube so the bore stays full size. On a long run with several takeoffs that difference shows up as pressure at the fixture.
6) How is the Sioux Chief 641WG tee packaged for stocking?
Cartons of 20 each. That is the stocking unit for distributors and plumbing contractors loading a truck for a repipe or a multi-unit rough-in, rather than a single-piece pack.
7) Can this tee be buried in a wall or under a slab?
The 641WG is made for behind-the-wall and under-floor rough-in branch takeoffs, which is its stated application. Local code governs whether any fitting may be concealed without access or placed under a slab, so check your jurisdiction before burying a joint.
