Sioux Chief 647WG2 1/2" FIP x 1/2" F1960 No-Lead Brass Adapter

The Sioux Chief 647WG2 is a 1/2" FIP x 1/2" F1960 no-lead brass adapter designed to transition threaded iron pipe into PEX expansion tubing on rough-in supply lines. Machined as a single one-piece brass body, it mates a 1/2" female iron pipe (FIP) thread on one end to a 1/2" F1960 PEX expansion connection on the other, giving installers a durable transition point behind the wall or under the floor. Because the fitting is no-lead brass, it is built for potable water supply installations where a threaded stub-out needs to convert to PEX expansion tubing without adding extra couplings.

Key Features

  • Trade Size: 1/2" FIP x 1/2" F1960 for a direct, one-fitting transition between threaded iron pipe and PEX expansion tubing.
  • Durable Construction: One-piece no-lead brass body resists corrosion and stands up to rough-in installation behind walls and under floors.
  • Dual Connection Design: A 1/2" FIP threaded end pairs with a 1/2" F1960 PEX expansion end, combining two connection types in a single fitting instead of two separate adapters.
  • No-Lead Brass: Manufactured from no-lead brass alloy suited to potable water supply lines.
  • One-Piece Body: Single-piece machined construction reduces the number of joints and potential leak points compared to multi-part adapter assemblies.
  • Rough-In Application: Sized for 1/2" branch and supply runs typical of residential and light commercial water distribution.

Why Sioux Chief?

Sioux Chief manufactures the 647WG2 from one-piece no-lead brass for dependable performance in potable water rough-in applications. The single-piece design reduces the number of joints and potential leak points compared to multi-component adapters, giving plumbing contractors a durable transition fitting between threaded pipe and PEX expansion systems on the job site. It is a straightforward, no-lead brass solution for converting a threaded stub-out to PEX expansion tubing without stacking multiple fittings.

Sioux Chief 647WG2 – Frequently Asked Questions

1) What does the F1960 end on the Sioux Chief 647WG2 adapter connect to?
The F1960 end is a 1/2 inch PEX expansion connection, the cold-expansion style where the PEX tubing and ring are expanded and shrink back onto the fitting barb. It works with 1/2 inch PEX-a expansion tubing and rings, not with crimp or press PEX systems. The other end of the 647WG2 is a 1/2 inch FIP (female iron pipe) thread, so one fitting takes you from a threaded stub-out straight to PEX expansion tubing.
2) Does the 647WG2 thread onto a male 1/2 inch pipe nipple or into a female fitting?
The threaded side is FIP, meaning female iron pipe, so it threads ONTO a 1/2 inch male NPT nipple or male-threaded stub-out. If what you have sticking out of the wall is a female threaded port, you need a male-thread (MIP) x F1960 adapter instead.
3) Is the 647WG2 adapter safe for drinking water lines?
It's machined from no-lead brass and is intended for potable water supply, which is what you want on residential and light commercial domestic water rough-in. Typical uses are threaded-to-PEX conversions behind walls and under floors on 1/2 inch branch and supply runs.
4) Do I need to seal the threads on the FIP side of this PEX adapter?
Yes, the FIP side is a tapered NPT thread and gets thread sealant or PTFE tape rated for potable water, same as any iron pipe joint. The F1960 side takes no sealant at all, it's a cold-expansion mechanical joint made with a PEX-a expansion ring and tool.
5) How does a one-piece brass adapter compare to stacking two separate fittings?
Stacking a threaded adapter plus a separate PEX expansion fitting adds a joint, and every joint behind a wall is a potential leak point. The 647WG2 is machined as a single brass body that carries both the 1/2 inch FIP thread and the 1/2 inch F1960 expansion end, so the transition is one piece with no intermediate connection to make up on site.
6) How is the Sioux Chief 647WG2 packaged for a plumbing contractor buying in volume?
The 647WG2 is cased 50 each, so a full case covers a multi-unit or tract rough-in without reordering. It's made in the United States.
