Sioux Chief 616-02C Shower WallNut Shower Arm Adapter, Chrome Finish
The Sioux Chief 616-02C is a Shower WallNut™ shower arm adapter finished in chrome, engineered to let a plumber stub out a shower arm connection the same way a copper tube stub-out is run to any other fixture. Instead of relying on thread sealant or P.T.F.E. tape at a hidden joint inside the finished wall, the Shower WallNut™ system makes the stub-out-to-shower-arm connection outside the finished wall, so the rough-in joint is visible and serviceable rather than buried behind drywall or tile. This design is intended for rough-in plumbers and contractors setting up shower arm stub-outs on copper tube systems where leak-free, inspectable connections at the finished wall are a priority.
Key Features
- Shower WallNut™ System: Stub out with copper tube just like any other fixture, keeping the rough-in process consistent with standard copper stub-out practices.
- No Sealant Required: DO NOT use thread sealant or P.T.F.E. tape on the Shower WallNut™ end of the shower arm — the system is designed to seal without it.
- Exterior Connection Point: The stub-out to shower arm connection is made outside the finished wall, ensuring there are no hidden leaks behind the finished wall once the installation is complete.
- Install Tool Compatible: A shower arm installation tool allows for an easier install with no external damage to the chrome finish or the arm itself.
- Chrome Finish: Finished in chrome to match standard shower arm and trim hardware at the wall penetration point.
- Warranty Requirement: For warranty coverage, the Shower WallNut™ system MUST be installed using a copper stub out together with the Sioux Chief #525-16WLB bracket.

Why Sioux Chief?
Sioux Chief designed the Shower WallNut™ system to move the stub-out-to-shower-arm joint outside the finished wall, eliminating the guesswork of a sealed connection hidden behind tile or drywall. Paired with the required copper stub out and #525-16WLB bracket, the 616-02C gives plumbers a chrome-finished, tool-friendly connection built for straightforward, leak-aware rough-in work.

Sioux Chief 616-02C – Frequently Asked Questions
1) How does the Sioux Chief Shower WallNut 616-02C keep the shower arm joint out from behind the tile?
The 616-02C moves the stub-out-to-shower-arm connection outside the finished wall. You run copper tube to the stub-out the same way you would for any other fixture, and the joint that ties the arm on sits in front of the drywall or tile where it can be seen and serviced. Nothing is buried, so a weeping thread is visible at the escutcheon instead of inside the wall cavity.
2) Do I need to use pipe dope or Teflon tape on the Shower WallNut shower arm?
No, and this one matters. Sioux Chief specifically says not to use thread sealant or PTFE tape on the Shower WallNut end of the shower arm. The system seals without it, and adding tape or dope works against the design. Treat it as a dry assembly on that end.
3) What else do I have to order with the Sioux Chief 616-02C to install it correctly?
Two things beyond the adapter itself: a copper stub out, and the Sioux Chief 525-16WLB bracket. Sioux Chief requires the Shower WallNut system be installed with both. A shower arm installation tool is also worth having, since it drives the arm without marring the chrome.
4) Will the Sioux Chief 616-02C work on a PEX or CPVC shower riser?
The Shower WallNut 616-02C is built around a copper tube stub-out, and the required installation uses a copper stub out with the 525-16WLB bracket. If your riser is PEX or CPVC, you would need a transition to copper at the stub-out, or a drop-ear elbow arrangement suited to that piping instead.
5) Can I use the Shower WallNut 616-02C on a remodel where the wall is already finished?
Yes, provided you can get to the riser to set a copper stub out and mount the 525-16WLB bracket. Renovation work is one of its stated applications, and the appeal is the same as in new construction: the joint lands outside the tile, so it stays inspectable after the wall closes up.
6) How do I tighten the shower arm without scratching the chrome?
Use a shower arm installation tool rather than pipe wrench jaws. Sioux Chief notes the tool makes the install easier with no external damage to the chrome finish or the arm, which matters on a part that stays visible at the wall.
7) Is the Sioux Chief 616-02C finish going to match a standard chrome shower arm and escutcheon?
It is chrome-plated, so it reads the same as standard polished chrome shower arms and trim at the wall penetration. That is the point of the finish here, since this part is visible at the finished wall rather than hidden.
8) How is the Sioux Chief 616-02C packaged, and is it sold as a single piece?
Sioux Chief packs the 616-02C 25 each per carton, which suits new-construction and multi-family work where you are roughing in many showers at once. The orderable item is the single model 616-02C.
