Sioux Chief 633XG18FPT – Frequently Asked Questions

1) What size connections does the Sioux Chief 633XG18FPT water heater connector have?
It's a 3/4 inch PEX end on one side and a 3/4 inch FIP swivel nut on the other, sized for standard water heater supply lines. The overall length is 18 inches, which lets you land the shutoff at a comfortable height above the heater instead of buried behind it.
2) Do I need pipe dope or tape on the FIP swivel nut of this water heater connector?
No. The brass FIP swivel nut seals on the included gasket, and Sioux Chief specifies not to use pipe dope on the FIP swivel threads. Hand tighten onto the heater nipple and snug it with a wrench; the gasket does the sealing.
3) Does this connector have a built-in shutoff valve, or do I need to add one?
A full-port ball valve is integrated into the 633XG18FPT, rated 600 WOG, so you get a dedicated shutoff at the water heater without teeing in a separate valve. Full port means the bore matches the line, so there's no flow restriction at the shutoff.
4) Can I use a PEX connector on a water heater with steel or copper nipples without a dielectric union?
The 633XG18FPT is built as a dielectric fitting, so the connection itself breaks the galvanic path between dissimilar metals at the heater. It's made from no-lead/DZR brass with Type L copper tube components, and Sioux Chief calls out full-flow dielectric construction that eliminates galvanic corrosion at the joint. Local code still governs, but you are not adding a separate dielectric union to make this work.
5) Is the Sioux Chief 633XG18FPT no-lead compliant for potable water?
Yes. The connector is no-lead compliant and built from NL/DZR brass, which also resists dezincification on aggressive water. That's the material spec inspectors look for on potable hot water supply.
6) Should I use a PEX water heater connector like this one or a braided stainless flex line?
This one is for a PEX distribution system. The 633XG18FPT terminates in a 3/4 inch PEX end that you crimp or clamp into your PEX run, with an 18 inch rigid Type L copper body and an integrated ball valve between the PEX and the heater. A braided flex simply bridges the heater nipple to an existing copper or threaded stub and carries no valve. Pick this when you're running PEX and want the shutoff built into the connection.
7) Can I use this connector on a water heater replacement, or is it new construction only?
Both. Sioux Chief lists the 633XG series for new construction and for water heater replacement and retrofit work. On a changeout, the 3/4 inch FIP swivel spins onto the existing heater nipple without rotating the rest of the assembly, so you're not fighting the PEX run to get the threads started.
8) How many Sioux Chief 633XG18FPT connectors come in a carton?
They ship 10 each per carton, which is how most supply houses buy them for new construction runs. The part is made in the United States, a detail that matters on federally funded and Buy American jobs.
