Sioux Chief 633WG18 Water Heater Connector, 3/4" FIP Swivel x 3/4" PEX (F1960)

The Sioux Chief 633WG18 is a flexible water heater connector built from Type L copper tube, designed to join a 3/4" FIP swivel connection to a 3/4" F1960 PEX expansion fitting over an 18" overall length. The brass FIP swivel nut includes a factory-installed gasket, and the connector is engineered for full flow with no internal restriction, making it a dependable rough-in choice for water heater hookups and copper-to-PEX transitions installed behind the wall or under the floor. Manufactured in the United States, it is built for plumbers who need a reliable, code-conscious connection between copper supply piping and PEX tubing at the water heater.

Sioux Chief 633WG18 – Frequently Asked Questions

1) Do I need to use pipe dope or Teflon tape on the swivel nut?
No. The brass FIP swivel nut on the 633WG18 ships with a factory-installed gasket that makes the seal, and pipe dope should not be applied to those swivel threads. Thread it on clean and tighten against the gasket.
2) Is the Sioux Chief 633WG18 lead-free for potable water?
The connector is built with a no-lead, dezincification-resistant (DZR) brass swivel nut and the solder joint on the copper tube is made lead-free. That is the no-lead construction called for on potable water heater connections.
3) How long is the 633WG18 water heater connector, and will 18 inches reach from the heater to my overhead piping?
Overall length is 18 inches, measured end to end including the swivel nut. That covers the typical gap between a tank nipple and a nearby stub-out or transition point. If your rough-in leaves more than roughly a foot and a half of travel, you'll need a longer connector or a rigid run with fittings.
4) Does a flexible copper connector like this cut down flow to the water heater?
Not on the 633WG18. It is a full-flow design with no internal restriction through the body, so the 3/4 inch bore carries through from the FIP swivel to the PEX end. Some corrugated and braided connectors neck down internally; this one does not.
5) Can I use the 633WG18 to transition from copper piping to PEX somewhere other than a water heater?
Yes. Because one end is a 3/4 inch FIP swivel and the other is a 3/4 inch F1960 PEX expansion connection, it works as a copper-to-PEX transition in rough-in work behind a wall or under a floor, not just at the tank. Typical uses listed by Sioux Chief include new construction and remodel rough-in as well as replacing an existing water heater connector.
6) What is the tube on this connector actually made of, and will it hold up on continuous hot water duty?
The body is Type L copper tube, which is the heavier-wall copper commonly run for domestic water, paired with a DZR brass swivel nut that resists dezincification in aggressive water. It is rated by Sioux Chief for water heater service on both residential and commercial installs.
7) How does the 633WG18 come packaged for a multi-unit job?
It ships 25 each per carton, which suits crews doing repeat water heater hookups across apartments or a tract build. Each piece is model 633WG18, made in the United States.
