Sioux Chief 641WP333 F1960 PEX Full-Flow Tee, 3/4" x 3/4" x 3/4"

Sioux Chief 641WP333 F1960 PEX Full-Flow Tee, 3/4" x 3/4" x 3/4"

The Sioux Chief 641WP333 is a 3/4" x 3/4" x 3/4" PEX tee built for F1960 expansion-style connections, giving plumbers a branch fitting that mates directly with ASTM F1960 PEX tubing systems during rough-in. Its full-flow, no-restriction body keeps the internal bore open through the run and branch, so pressure and flow stay consistent instead of choking down at the fitting the way a standard-bore tee can. Packaged 200 EA per carton, it is sized for distributors and contractors stocking high-volume residential and light commercial PEX rough-in work, and it drops into a job the same way any other F1960 branch fitting does, with no change to installation sequence.

Key Features

• Trade Size: 3/4" x 3/4" x 3/4" tee for branching PEX runs behind walls, in manifolds, or under floors during rough-in.
• F1960 Expansion Connection: Engineered for ASTM F1960 PEX expansion fittings, matching cold-expansion PEX tubing and expansion rings used in rough-in supply lines.
• Full-Flow, No-Restriction Design: The fitting body does not narrow the flow path, so water volume and pressure are preserved through both the straight run and the branch outlet.
• Three-Way Tee Configuration: Splits a single PEX line into a branch connection without an additional coupling, simplifying manifold and trunk-and-branch layouts.
• Consistent Connection Method: Lets installers stay on a single F1960 expansion connection type across a run instead of mixing crimp, cinch, or push-fit fittings.
• Bulk Carton Packaging: Supplied 200 EA per carton for stocking plumbing wholesalers and production plumbing crews on volume jobs.

Why Sioux Chief?

Sioux Chief builds rough-in plumbing fittings that plumbing contractors rely on to keep water distribution systems flowing without added restriction, and the 641WP333 tee carries that full-flow philosophy into every branch connection. Its F1960-compatible expansion design lets installers stay within one PEX connection method across a job instead of mixing fitting types mid-run. For distributors and crews standardizing on PEX rough-in, this tee offers a consistent, code-referenced connection standard backed by Sioux Chief's plumbing supply expertise and packaged for the volume that production plumbing work demands.
