Sioux Chief 647XG2E3 1/2" FIP x 1/2" PEX No-Lead Drop Ear Elbow

The Sioux Chief 647XG2E3 is a 1/2" FIP x 1/2" PEX No-Lead drop ear elbow built for shower riser, tub spout, and other non-pressure fitting applications. Its internal 1/2" FIP thread accepts a shower arm or tub spout nipple, while the 1/2" PEX outlet connects directly into the PEX tubing run behind the wall. The drop ear body includes mounting ears so the fitting can be screwed to blocking or a stud, giving the finished shower arm or tub spout a rigid anchor point instead of relying on the tubing alone. The No-Lead construction makes this elbow suited to potable water supply lines, and it is designed as a rough-in transition fitting installed before the wall surface is closed up.

Key Features

  • Trade Size: 1/2" FIP x 1/2" PEX connection sized for shower riser and tub spout rough-in runs.
  • Internal FIP Thread: The female iron pipe thread side accepts a standard 1/2" shower arm or tub spout nipple for the finished trim.
  • PEX Outlet: The 1/2" PEX connection ties directly into the branch supply line run behind the finished wall, keeping the transition to threaded pipe in one fitting.
  • Drop Ear Mounting: Integral mounting ears let the fitting be fastened to blocking or a stud, giving the shower arm or tub spout a rigid, immovable anchor point that will not shift or work loose over time.
  • No-Lead Construction: No-Lead body construction suited to potable water supply applications.
  • Non-Pressure Fitting Use: Intended for shower risers, tub spouts, and similar non-pressure fitting applications rather than pressurized main runs.
  • Rough-In Placement: Installed and anchored behind the wall before rough-in inspection and wall closure, ahead of trim-out.

Why Sioux Chief?

Sioux Chief builds this drop ear elbow with a No-Lead body and integral mounting ears so plumbers get a stable, wall-anchored transition from PEX tubing to a threaded shower arm or tub spout nipple. It is a straightforward, rough-in focused fitting for shower and tub installations where a secure, immovable connection point behind the finished wall matters, saving a callback if the fixture connection were left to the tubing alone. The No-Lead construction keeps it suited to potable water supply lines, and Sioux Chief packages it 50 EA per carton for rough-in crews stocking multiple bath installations.

Sioux Chief 647XG2E3 – Frequently Asked Questions

1) Will the Sioux Chief 647XG2E3 drop ear elbow accept a standard 1/2 inch shower arm?
Yes. The 647XG2E3 has a 1/2 inch FIP (female iron pipe) thread on one side, which takes a standard 1/2 inch shower arm or a tub spout nipple for trim-out. The other side is a 1/2 inch PEX connection that ties into the branch line behind the wall, so the PEX-to-threaded transition happens in one fitting.
2) Can I use this PEX drop ear elbow on a pressurized main water line, or only for shower arms?
It is built for shower risers, tub spouts, and similar non-pressure fitting applications, not for pressurized main runs. Use it as the terminal transition where a shower arm or spout nipple threads in. For a pressurized branch or main, pick a rated pressure fitting instead.
3) Do I need wood blocking behind the wall to mount this elbow, or can it hang on the PEX?
Mount it. The drop ear body has integral mounting ears meant to be screwed to blocking or a stud, which is the whole point of the fitting: the shower arm or tub spout gets a rigid anchor instead of loading the tubing. Plan blocking between studs at your shower arm or spout height during rough-in. Hanging it off the PEX alone defeats the design and is how spouts work loose later.
4) Is this drop ear elbow safe for potable drinking water lines?
The Sioux Chief 647XG2E3 uses No-Lead body construction, which is what makes it suitable for potable water supply lines. That is the construction standard listed for the fitting.
5) When in the job does this fitting get installed?
It is a rough-in fitting. It goes in and gets anchored to the framing before rough-in inspection and before the wall surface is closed up, with the shower arm or spout threaded in later at trim-out. If drywall is already on, you are into opening the wall or working through the spout penetration.
6) Will this elbow work on 3/8 inch or 3/4 inch PEX?
No. The 647XG2E3 is 1/2 inch on both sides, 1/2 inch FIP thread and 1/2 inch PEX. For another tubing size you need the matching size of drop ear elbow; this one will not adapt.
7) Can I use a drop ear elbow for both a shower arm and a tub spout on a tub/shower valve?
Yes, the same 1/2 inch FIP x 1/2 inch PEX drop ear elbow serves either. Typical practice is one anchored at shower arm height above the valve and one at spout height below it, each screwed to blocking so the finished trim cannot shift. Both threaded outlets take a standard 1/2 inch nipple or arm.
8) How many Sioux Chief 647XG2E3 drop ear elbows come in a carton?
Cartons are packed 50 each, which suits a crew roughing in multiple baths rather than a one-off repair. The fitting is made in the United States.
