Sioux Chief 631XG02FP 2-1/2" PEX x 3/4" FIP Swivel Elbow with Full Port Ball Valve, No-Lead

Sioux Chief PEX x FIP Swivel Elbow with Full Port Ball Valve, No-Lead

This Sioux Chief fitting is a no-lead rough-in elbow that transitions 2-1/2" PEX to 3/4" FIP with a swivel connection, built around a full port ball valve for shutoff or isolation behind the wall. The brass FIP swivel nut ships with its gasket already in place, and the body is rated NL/DZR (no-lead, dezincification resistant) for potable-water rough-in work. A dielectric fitting design helps isolate dissimilar pipe materials at the joint, and Sioux Chief packs this elbow 12 to a carton for crews stocking multiple rough-ins on the same job. Because the ball valve is built into the elbow body, a plumber can isolate a fixture or branch line at the transition point itself instead of sourcing and sweating in a separate stop valve, which keeps the behind-the-wall assembly more compact and reduces the number of joints exposed to future callbacks.

Key Features

• Trade Size: 2-1/2" PEX x 3/4" FIP swivel connection for rough-in transitions.
• Full Port Ball Valve: Integrated FP valve body allows shutoff/isolation at the fitting instead of running a separate stop.
• Brass FIP Swivel Nut: Ships with gasket installed, so the joint is ready to make up on the swivel side without sourcing a separate seal; do not use pipe dope on the FIP swivel threads.
• No-Lead / DZR Construction: NL/DZR brass body for potable-water rough-in applications, resisting dezincification in aggressive water conditions.
• Dielectric Fitting: Helps isolate dissimilar pipe materials at the connection point to reduce galvanic corrosion risk at the transition.
• Lead-Free Solder Joint: Solder-side connection is lead-free per manufacturer spec, matching the no-lead body.
• 3/4" Type L Copper Reference: Manufacturer fitting data references 3/4" Type L copper compatibility at this connection.
• Swivel Design: The FIP swivel nut allows the fitting to be rotated into alignment during assembly without twisting the upstream PEX run.

Why Sioux Chief?

Sioux Chief builds this elbow with a no-lead, DZR brass body and a full port ball valve built into the fitting, giving plumbers a shutoff point without adding a separate stop to the rough-in. The brass FIP swivel nut arrives with its gasket pre-installed, and the dielectric design and lead-free solder-side joint reflect Sioux Chief's approach to code-oriented rough-in hardware for potable-water systems. Sold 12 to a carton, it's sized for crews stocking multiple identical transitions across a job rather than picking up single pieces at the counter.
