Sioux Chief 638X Strapped Type L Copper Stub-Out, 1/2" PEX x Close Connection

The Sioux Chief 638X is a strapped, code-ready Type L copper stub-out built for closet and lavatory rough-in work, giving plumbers a fast way to stub up through the floor while holding the fitting square until the rough-in is finished out. Every unit in this family shares a 1/2" PEX x Close connection, transitioning cleanly from PEX water distribution tubing to a close-coupled fixture supply, and the family is available in 8" and 12" stub-out lengths so installers can match different floor and wall rough-in depths while keeping the same connection size and strapped design across the range. This stub-out is not designed to be used as a permanent air chamber, so plan the rough-in accordingly.

Key Features

  • Trade Size: 1/2" PEX x Close connection shared across both length options, sized for closet and lavatory supply stub-outs.
  • Available Lengths: Offered in 8" and 12" stub-out lengths so installers can match different floor and wall rough-in depths without switching platforms.
  • Durable Construction: Machined from Type L copper for a durable, corrosion-resistant stub-out that holds up to the repeated stress of rough-in and finish plumbing work.
  • Strapped Design: An integrated strap makes it easy to stub up through the floor for closets or lavatories, holding the fitting square and secure while the rough-in is finished out.
  • PEX x Close Connection: One end accepts PEX tubing while the close end simplifies the transition to fixture supply connections, reducing the number of extra fittings needed at the stub-out.
  • Rough-In Efficiency: The strapped body paired with the 1/2" PEX x Close connection speeds up closet and lavatory rough-in by keeping the stub-out aligned and ready for finish trim.
  • Important Usage Note: Not intended for use as a permanent air chamber — install per code for its intended stub-out application only.

Sioux Chief 638X208 – Frequently Asked Questions

1) What sizes does the Sioux Chief 638X copper stub-out come in?
Two lengths on the same 1/2 inch connection: 8 inch (MPN 638X208) and 12 inch (MPN 638X212). Pick the length by how deep your rough-in sits relative to the finished wall or floor. Both are Type L copper with the same strap and the same 1/2 inch PEX x Close ends, so switching lengths does not change anything else about the install.
2) What does PEX x Close mean on this Sioux Chief stub-out?
One end takes 1/2 inch PEX water distribution tubing, and the other is a close end that goes straight to the fixture supply connection. That means you crimp or clamp your PEX run onto one side and land the stop or supply on the other without adding transition fittings at the stub-out.
3) Can I use the 638X stub-out as an air chamber for water hammer?
No. The 638X is not designed to serve as a permanent air chamber, and a capped copper riser loses its air cushion over time anyway. Use it strictly as a supply stub-out at closets and lavatories, and handle water hammer with a proper arrestor.
4) What is the strap on the Sioux Chief 638X for?
The integrated strap is how you fix the stub-out to framing when you stub up through the floor at a closet or lavatory. It holds the tube square and keeps it from moving while the rest of the rough-in and the finish trim go in, so your escutcheon and stop line up where you set them.
5) Is Type L copper the right grade for a residential water supply stub-out?
Type L is the heavier-wall copper commonly specified for potable water distribution in buildings, thicker than Type M, and it is what the 638X is built from. For a stub-out that gets bumped during drywall, tile and trim work, the heavier wall is the reason to choose it over lighter tube.
6) Will the 638X work for both a toilet and a lavatory rough-in?
Yes, both. It is built for closet and lavatory supply stub-outs on 1/2 inch PEX distribution lines, in new construction or remodel work. The 1/2 inch size is the standard supply for a water closet and a lav faucet, so one part covers both openings on the same bathroom rough-in.
7) How are these stub-outs packaged for a multi-unit job?
They ship 100 each per case, which suits multi-family and tract work where you are setting the same closet and lav rough-in repeatedly. The 638X is manufactured in the United States, which matters on jobs carrying a domestic sourcing requirement.
