Sioux Chief 687 Blue ABS Single-Valve Service Box with Drain

The Sioux Chief 687 is a blue ABS service box built for rough-in installation of a single quarter-turn ball valve with an integrated drain. The family covers both the F1807 and F1960 PEX expansion connection standards, available in sizes ranging from 1/2\" through 1-1/4\" (including 1/2\", 3/4\", 1\", and 1-1/4\" options in the F1960 series and 1/2\", 3/4\", and 1\" in the F1807 series), each configured as a matching inlet x outlet pair (e.g. 3/4\" x 3/4\") for direct connection to PEX tubing. The durable ABS box mounts securely to a stud or between studs, and the box and valve are protected during construction by an included debris cover that keeps out dust, mud, and paint until finish-out. Because it combines a box, a full-flow 600WOG valve, and a drain into a single rough-in product, the 687 replaces multiple individual parts, cutting down on job-site mess, waste, and the buying, stocking, and handling that comes with assembling those components separately.

Key Features

  • Trade Size Range: Available in matching inlet x outlet sizes from 1/2\" through 1-1/4\" for direct PEX tubing hookup at the service box.
  • Durable Construction: Molded ABS box designed to mount securely to a stud or between studs for a stable rough-in installation.
  • Connection Type: F1807 or F1960 PEX expansion connections on both the inlet and outlet of the box, depending on selected size option.
  • Single Valve with Drain: Quarter-turn ball valve paired with an integrated drain in one enclosure, reducing the number of separate parts needed at rough-in.
  • Union Connection: The valve connects via a union fitting, making it easy to remove, repair, or replace the valve without disturbing the surrounding plumbing.
  • Full-Flow 600WOG Valve: Code-compliant full-flow ball valve rated 600WOG (working pressure, water, oil, gas) for dependable rough-in shutoff service across the entire size range.
  • Fire-Rated Wall Compatible: This model can be used in fire-rated wall assemblies.
  • Debris Cover Included: A protective cover shields the box and valve from dust, mud, and paint throughout the construction process.

Why Sioux Chief?

Sioux Chief engineers the 687 service box family around a patented design (#11,473,276), a code-compliant full-flow 600WOG valve, and a union connection that gives plumbers a serviceable, repairable shutoff point built directly into the wall, across the full F1807 and F1960 size range. The durable ABS box, secure stud-mounting, and included debris cover are built to survive the full rough-in-to-finish construction cycle, while the single-product design cuts down on the separate parts a plumber would otherwise have to source, stock, and install individually.

Sioux Chief 687-2XD – Frequently Asked Questions

1) What's the difference between the F1807 and F1960 versions of the Sioux Chief 687 service box?
It's the PEX connection standard on the inlet and outlet. F1807 is the copper crimp/cinch ring standard, F1960 is the cold-expansion (expander tool) standard, so you pick the one that matches the tubing system and tools you're already running on the job. The 687 covers F1807 in 1/2, 3/4 and 1 inch (687-2XD, 687-3XD, 687-4XD) and F1960 in 1/2, 3/4, 1 and 1-1/4 inch (687-2WD, 687-3WD, 687-4WD, 687-5WD). The 1-1/4 inch size is F1960 only.
2) Can the Sioux Chief 687 service box be installed in a fire-rated wall assembly?
Yes. The 687 single-valve box with drain is stated as usable in fire-rated wall assemblies, which is what separates it from boxes limited to non-rated partitions. It mounts to a stud or between studs in the rough-in.
3) Does the 687 service box come with the valve, or do I buy that separately?
The valve is included. The 687 is a single-assembly rough-in: ABS box, quarter-turn full-flow ball valve rated 600WOG, and an integrated drain, plus a debris cover to keep dust, mud and paint out until finish-out. That's the point of it, you're not sourcing a box, a valve and a drain separately.
4) If the shutoff valve inside the wall fails, do I have to open up the wall and re-plumb it?
No. The valve on the 687 connects through a union fitting, so it can be removed, repaired or replaced through the box without disturbing the PEX connections or surrounding plumbing. For property managers and MRO crews that's the main service argument for this box over a soldered or crimped-in-place stop.
5) Is the inlet and outlet on the Sioux Chief 687 the same size?
Yes, every 687 configuration is a matching inlet x outlet pair, so a 3/4 inch box is 3/4 x 3/4. There's no reducing option in the family, if you need a size change you make it in the tubing run before or after the box.
6) Do I need a drain-down connection at the box, or will a plain valve box do?
If you want to isolate and empty the branch without pulling a fixture, the 687 is the one to use, it pairs the quarter-turn ball valve with an integrated drain in the same enclosure. Typical use is single-fixture supply shutoff with drain-down behind the wall. If you only need shutoff and never need to bleed the line, the drain adds nothing you'll use.
7) Which Sioux Chief 687 part number do I order for 1 inch PEX?
For 1 inch, order 687-4WD if you're running F1960 cold-expansion PEX, or 687-4XD for F1807 crimp. Half inch is 687-2WD (F1960) or 687-2XD (F1807), and 3/4 inch is 687-3WD or 687-3XD. The largest size, 1-1/4 inch, is 687-5WD and only exists in F1960.
8) What pressure is the ball valve in the Sioux Chief 687 rated for?
The ball valve is a full-flow design rated 600WOG, meaning 600 psi working pressure on water, oil and gas service. That's well above any domestic water rough-in duty, so the valve is not the limiting component in a PEX supply run.
9) What is the Sioux Chief 687 box actually made of, and will it survive the rest of construction?
The box is molded blue ABS, mounted to a stud or between studs. It ships with a protective debris cover that keeps dust, mud and paint off the box and valve from rough-in through finish-out, so drywall and paint trades can work over it without fouling the valve.
