Sioux Chief 68765 Black ABS PRV Service Box, F1960 PEX Connection

The Sioux Chief 68765 is a durable black ABS service box built for rough-in installation of a pressure reducing valve on an F1960 PEX supply line. This service box is available in F1960 x F1960 PEX connection sizes ranging from 3/4" to 1", letting plumbers match the box to the branch or main line being served. The box mounts securely to a stud or between studs and ships with a PVC jumper installed at the factory for rough-in protection, allowing the quarter-turn ball valve and PRV assembly to be added later without exposing the connection to jobsite damage. A union connection on the valve body makes future repair or replacement straightforward, and the fully adjustable PRV complies with ASSE 1003, factory set to 60psi. All models in this line can be used in fire-rated wall assemblies, making the 68765 suitable for both standard residential rough-in and fire-rated partition installations where a dependable pressure-reducing service box is required behind the finished wall.

Key Features

  • Durable Construction: Black ABS box body designed to mount to a stud or between studs for secure rough-in placement.
  • Quarter-Turn Ball Valve: Integrated ball valve with a union connection that allows the valve to be removed and repaired or replaced without cutting the line.

Sioux Chief 687-3RWW – Frequently Asked Questions

1) Can a PRV service box be installed in a fire-rated wall assembly?
Yes. Every model in the Sioux Chief 687 service box line, including the 68765, is approved for use in fire-rated wall assemblies as well as standard stud framing. That matters on multi-family corridor and demising walls where a recessed box normally has to come out of the plan.
2) What pressure is the PRV in the Sioux Chief 68765 set to, and can I change it?
It ships factory set at 60 psi and the valve is fully adjustable, so you can dial it up or down to suit the fixtures or local code limit after trim-out. The valve complies with ASSE 1003, the standard for water pressure reducing valves on domestic supply.
3) Do I have to install the PRV at rough-in, or can it wait until trim?
It can wait. The box ships with a PVC jumper installed at the factory, so you can tie in the PEX, pressure test, and close up the wall with the line protected. The quarter-turn ball valve and PRV assembly go in later, which keeps the valve trim out of the way of drywallers and off the jobsite theft list.
4) If the pressure reducing valve fails later, do I have to cut the PEX line open?
No. The valve body uses a union connection, so the ball valve and PRV can be pulled for repair or replacement without cutting into the PEX. That is the main reason to use a service box instead of an inline PRV soldered or expanded into the wall cavity: the serviceable part stays accessible behind the cover plate.
5) Is this a whole-house pressure reducing valve box or just a branch shutoff?
It is a PRV box, not a plain shutoff. The 68765 carries an adjustable ASSE 1003 pressure reducing valve plus a quarter-turn ball valve, which is what you want at the point of entry for whole-house pressure control on a PEX system. If all you need is an accessible isolation valve for a single branch with no pressure reduction, a PRV box is more hardware than the job calls for.
6) How does the Sioux Chief 687 PRV service box come packaged for a multi-unit job?
It is packaged 9 each per case, which suits multi-family and tract work where you are setting one box per unit. Both the 3/4 inch and 1 inch F1960 versions are separate part numbers, 687-3RWW and 687-4RWW, so order by the line size in each building.
