Sioux Chief 641XG No-Lead Brass One-Piece PEX Branch Tee

Sioux Chief 641XG No-Lead Brass One-Piece PEX Branch Tee

The Sioux Chief 641XG is a one-piece, no-lead brass PEX tee built in a three-way branch configuration for behind-the-wall rough-in plumbing, available across trade sizes from 1/2" to 1" including 1 x 1", 3/4 x 3/4", 3/4 x 1/2", and 1/2 x 1/2" branch combinations. Its single-piece brass body forms a branch connection point on PEX tubing runs, letting a plumber tee off an existing supply line without adding extra soldered or threaded joints. The no-lead brass construction suits potable water supply distribution in residential and commercial PEX systems, with sizing that lines up with common PEX tubing runs used in rough-in work.

Key Features

• Trade Size Range: 1/2" - 1", available in 1 x 1", 3/4 x 3/4", 3/4 x 1/2", and 1/2 x 1/2" branch configurations for connections on PEX tubing runs.
• One-Piece Construction: molded as a single brass body rather than an assembled multi-part fitting, reducing the number of joints behind the wall.
• No-Lead Brass: brass alloy formulated without lead content, appropriate for potable water supply lines.
• Three-Way Tee Configuration: branches a main PEX supply run into a secondary line without adding a manifold takeoff.
• Rough-In Ready: sized and configured for installation behind walls, under floors, and in mechanical rooms alongside other PEX rough-in components.
• Corrosion-Resistant Body: brass construction stands up to the damp, enclosed conditions typical of rough-in plumbing chases.

Why Sioux Chief?

Sioux Chief builds the 641XG tee family as one-piece no-lead brass fittings, avoiding the multi-part assemblies and extra sealing points found in lower-quality tees. For plumbers and contractors running PEX supply lines, that single-piece brass body means one less connection to inspect once the wall is closed up. Across the 1/2" to 1" trade size range, the 641XG family delivers dependable three-way PEX branch connections for residential and commercial rough-in work.
