Sioux Chief 647WG43 No-Lead Brass FIP x PEX Adapter, 1" FIP x 3/4" F1960

The Sioux Chief 647WG43 is a one-piece no-lead brass adapter built for transitioning rough-in plumbing from 1" female iron pipe (FIP) threaded connections to 3/4" F1960 PEX expansion fittings. This fitting is designed for behind-the-wall and under-floor installations where a plumber or contractor needs a reliable threaded-to-PEX transition without introducing a weak point in the system. Machined from solid no-lead brass in one piece, the adapter is built to hold up to the demands of daily rough-in work on both new construction and renovation jobs. The 1" FIP x 3/4" F1960 configuration makes it a practical choice wherever a contractor is stepping down from standard iron pipe thread to PEX tubing using expansion-style connections.

Key Features

  • Trade Size: 1" FIP x 3/4" F1960 for stepping down from threaded iron pipe to PEX expansion tubing in rough-in runs.
  • Durable Construction: One-piece no-lead brass body for long-term durability in potable water rough-in applications.
  • Connection Type: 1" FIP (female iron pipe) threaded connection on one end for mating to standard threaded fittings, valves, or stub-outs.
  • PEX Expansion Fitting: 3/4" F1960 expansion-style end for use with PEX expansion rings and tooling on the opposite side of the adapter.
  • No-Lead Brass: Formulated as a no-lead alloy, supporting compliance-driven rough-in plumbing installs.
  • One-Piece Design: Machined as a single piece rather than an assembly, reducing potential leak points at the transition.

Sioux Chief 647WG43 – Frequently Asked Questions

1) What size pipe thread does the 647WG43 screw onto?
One end is a 1 inch FIP, female iron pipe thread, so it threads onto a 1 inch male NPT nipple, valve, or stub-out. The other end steps down to 3/4 inch PEX. If your threaded side is 3/4 inch, this is the wrong adapter, you want a 3/4 x 3/4 configuration.
2) Can I use this adapter to tie PEX into an existing galvanized or iron pipe stub-out?
That's exactly the transition it's built for. Thread the 1 inch FIP end onto a 1 inch male iron pipe stub-out, valve, or fitting, then expand 3/4 inch PEX-a onto the F1960 barb. It's intended for behind-the-wall and under-floor potable work on both new construction and renovation repipes. Note the step down: your PEX branch will be 3/4 inch, so size the run accordingly.
3) Is this brass adapter safe for potable drinking water lines?
It's machined from no-lead brass and sold for potable water rough-in, both residential and commercial. That's the alloy choice that matters when an inspector is looking at a drinking water distribution run.
4) Is the 647WG43 a one-piece fitting or two parts threaded together?
Single piece. The FIP thread and the F1960 expansion barb are machined into one brass body rather than assembled from a threaded adapter plus a separate PEX fitting, which removes a joint from the transition. For a plumber that also means one part to stock instead of two.
5) How many Sioux Chief 647WG43 adapters come in a carton?
They're packaged 25 each per carton, which suits a repipe or new-construction run where you're making the same threaded-to-PEX transition at many points. Made in the United States.
