Sioux Chief 638WG No-Lead Copper Stub Out, F1960 PEX Connection

The Sioux Chief 638WG is a 1/2" F1960 No-Lead Copper Stub Out, available in lengths from 8" to 15", built from Type L copper tube to combine the rigid versatility of a copper stub out with the easy connection of a PEX system. One end is formed for ASTM F1960 PEX expansion connections, while the Type L copper body accepts sweat, push-fitting, and compression valves on the finished end, giving plumbers a single fitting that bridges PEX rough-in piping to a fixture supply valve. This NL/DZR fitting is intended for use behind the wall or through a finished floor, stubbing up for closets, lavs, and other fixture locations where a clean, solid copper riser is preferred over flexible tubing. Whether the rough-in calls for the shorter 8" length or the longer 15" option, both share the same 1/2" F1960 connection, Type L copper construction, and NL/DZR formulation.

Key Features

  • Trade Size: 1/2" F1960 connection, available in 8" and 15" lengths for standard fixture stub-out applications.
  • Durable Construction: Type L copper tube provides a rigid, long-lasting stub out that stands up to repeated valve installation and removal.
  • PEX-to-Copper Transition: F1960 expansion end allows direct connection to PEX rough-in piping, eliminating the need for a separate transition fitting.
  • Multi-Connection Flexibility: Type L copper end accepts sweat, push-fitting, and compression valves, giving installers flexibility on the fixture-side connection method.
  • No-Lead/DZR Material: NL/DZR designation supports use in potable water rough-in applications.
  • Optional Mounting Bracket: An optional square bracket is available and is well suited for stubbing up through a floor at closets or lavatories, holding the stub out plumb during rough-in.

Why Sioux Chief?

Sioux Chief builds the 638WG stub out from Type L copper tube with a no-lead, DZR formulation, giving plumbers a dependable transition piece between PEX rough-in lines and fixture supply valves. By supporting sweat, push-fit, and compression connections on the copper end and a direct F1960 connection on the PEX end, this fitting simplifies rough-in work while keeping the finished connection point in durable copper, no matter which length is selected for the job.

Sioux Chief 638WG208 – Frequently Asked Questions

1) Will the Sioux Chief 638WG stub out connect directly to my PEX-A line without a separate transition fitting?
Yes. One end of the 638WG is formed for a 1/2 inch ASTM F1960 cold expansion connection, so it goes straight onto PEX-A with an expander tool and ring. No brass transition adapter in between. The other end is plain Type L copper tube for the fixture-side valve.
2) What kind of angle stop can I put on the copper end of a 638WG stub out?
The copper end is Type L tube, so it takes a sweat valve, a push-fit stop, or a compression stop. That lets you solder the stop on during rough-in or set a quarter-turn compression or push-fit stop at trim-out without changing the stub.
3) Is the 638WG stub out approved for potable water?
It carries a No-Lead designation and is built in a DZR (dezincification resistant) formulation, which is what supports its use on potable water rough-in. Made in the USA.
4) Can I use a copper stub out as the air chamber on a fixture branch?
No. The 638WG is not to be used as a permanent air chamber. It is a rough-in riser that transitions PEX to a fixture supply valve. If the job needs arrestor protection, specify a listed water hammer arrestor separately.
5) How do I hold the stub out plumb when I'm stubbing up through a floor at a toilet?
An optional square mounting bracket is available for the 638WG and is intended for exactly that: stubbing up through a floor at closets or lavatories, holding the riser plumb through rough-in and the pour or finish work. It is ordered separately from the stub out itself.
6) Why use a copper stub out instead of just running PEX to the stop?
Rigidity at the fixture. The 638WG gives a solid Type L copper riser at the trim point instead of flexible tubing, so the stop stays where you set it and the stub takes repeated valve installation and removal without deforming. It also lets the finished connection be copper while the rough-in behind the wall stays PEX.
7) Does the Sioux Chief 638WG work for commercial rough-in, or is it residential only?
Both. It is used in residential and commercial fixture rough-in, typically PEX-to-fixture transitions at lavatories and water closets, stub-ups through finished floors, and new construction or remodel work.
