Sioux Chief 633-G318FP No-Lead Washing Machine Supply Valve, 3/4" FSWVL x 3/4" MSWT

The Sioux Chief 633-G318FP is a no-lead, DZR (dezincification-resistant) supply valve built for washing machine and appliance water-line rough-in behind the wall. It pairs a 3/4" FSWVL (female sweat swivel) inlet, which threads onto the supply connection without disturbing the soldered joint, with a 3/4" MSWT (male sweat) outlet for a permanent soldered connection to copper tubing. The no-lead, DZR brass body resists dezincification and is intended for potable-water service, and the valve ships 10 per case, making it a practical stocking item for plumbing wholesalers, remodel crews, and new-construction rough-in jobs alike.

Key Features

  • Trade Size: 3/4" FSWVL x 3/4" MSWT connections sized to standard 3/4" copper supply lines.
  • No-Lead/DZR Construction: dezincification-resistant, no-lead brass body engineered for long-term durability in potable-water applications where zinc-alloy components are prone to corrosion.
  • FSWVL Inlet: female sweat swivel connection lets the valve rotate freely into alignment as it is threaded onto the supply line, so the installer never has to twist the soldered tubing on the other end.
  • MSWT Outlet: male sweat connection for a permanent soldered joint to 3/4" copper tubing, giving a solid, leak-resistant termination point.
  • Installation Note: do not use pipe dope on the FIP swivel threads, per manufacturer instructions - the swivel seat is designed to seal without added compound.
  • Case Packaging: packed 10 EA per case, sized for rough-in crews and distributors who need to keep this valve on hand for repeat appliance and fixture hookups.

Why Sioux Chief?

Sioux Chief builds the 633-G318FP supply valve from no-lead, DZR brass so it can stand up to potable-water service without the dezincification failures that plague lower-grade zinc-alloy valves. The FSWVL x MSWT connection set gives plumbers a swivel inlet for fast, twist-free alignment on the supply side and a solid sweat outlet for a permanent copper joint on the other, and the 10-per-case packaging keeps it easy to stock. For professional plumbers and contractors who need a dependable, code-conscious washing machine and appliance supply valve for behind-the-wall rough-in work, the Sioux Chief 633-G318FP is a straightforward, purpose-built choice.

Sioux Chief 633-G318FP – Frequently Asked Questions

1) What connections does the Sioux Chief 633-G318FP washing machine valve have, and what do I need to hook it to?
The 633-G318FP has a 3/4 inch FSWVL (female sweat swivel) inlet and a 3/4 inch MSWT (male sweat) outlet. The inlet threads onto a supply connection and spins freely into alignment, so you are not twisting a soldered joint to line it up. The outlet is a male sweat end that solders permanently into 3/4 inch copper tubing, so you will need solder, flux and a torch to finish the outlet side.
2) Can I use pipe dope or thread sealant on the swivel threads of this Sioux Chief supply valve?
No. Per the manufacturer instruction for the 633-G318FP, do not put pipe dope on the FIP swivel threads. The swivel seat seals on its own, and compound on the threads can interfere with that seat. Solder the male sweat outlet into the copper as normal.
3) Is this Sioux Chief valve safe for potable water lines?
Yes. The 633-G318FP body is no-lead, dezincification-resistant (DZR) brass and is intended for potable-water service. DZR brass is specified where ordinary zinc-alloy brass fails from dezincification, which is the usual cause of pinhole leaks and seized stems on cheaper supply valves in aggressive water.
4) Is this a behind-the-wall rough-in valve or a surface-mount washer box valve?
It is a rough-in valve. The 633-G318FP is a supply valve for washing machine and appliance water lines behind the wall, with sweat connections on both ends rather than a hose-thread outlet or a finished box face. If you need a finished laundry outlet with hose bibs and a face plate, that is a washing machine outlet box, not this part.
5) Why choose a swivel inlet valve instead of a plain sweat-by-sweat stop?
The swivel inlet lets the valve rotate into alignment as it threads on, so the handle can be pointed where you want it without rotating tubing that is already soldered at the far end. A straight sweat-by-sweat stop locks its orientation when you solder it, which is fine on an open run but awkward in a tight stud bay or against a finished wall line.
6) How is the Sioux Chief 633-G318FP packaged for stocking?
It ships 10 each per case. That case quantity suits rough-in crews doing repeat appliance hookups and wholesalers keeping it on the shelf, rather than a one-off repair purchase.
7) Where is the Sioux Chief 633-G318FP made?
The 633-G318FP is made in the United States, which matters on public and institutional work carrying domestic-content requirements.
