Sioux Chief 642WP2 1/2" F1960 PEX 90° Elbow

The Sioux Chief 642WP2 is a 1/2" x 1/2" 90° elbow fitting built for PEX tubing systems using the ASTM F1960 cold expansion connection method. This plastic elbow is engineered as a full-flow fitting, meaning there is no internal restriction at the bend, allowing water to pass through at the same flow rate as straight PEX tubing. Designed for behind-the-wall rough-in plumbing applications, this fitting mates directly with 1/2" PEX tubing and is installed using an F1960 expansion tool and compatible expander rings, rather than crimp rings or clamps. The 90° bend allows plumbers to redirect PEX runs around corners, through wall cavities, and into fixture connections without kinking the tubing, which can restrict flow or damage the tubing wall over time.

Key Features

  • Trade Size: 1/2" x 1/2" connection sized for standard 1/2" PEX tubing runs in residential and light commercial rough-in.
  • Full-Flow Design: No internal restriction at the 90° bend, preserving water flow rate through the fitting compared to standard reduced-bore elbows.
  • 90° Elbow Configuration: Allows PEX tubing to change direction cleanly behind walls and in tight framing cavities without kinking the tube.
  • F1960 Connection Method: Engineered for the ASTM F1960 cold-expansion PEX connection system, requiring an expansion tool and compatible expander rings rather than crimping.
  • Durable Plastic Construction: Molded plastic body suited for concealed rough-in use behind walls, under floors, and in mechanical chases.
  • Bulk Packaging: Supplied in case quantities of 625 EA, suited for plumbing contractors and distributors stocking high-volume PEX rough-in jobs.

Sioux Chief 642WP2 – Frequently Asked Questions

1) What size PEX tubing does the Sioux Chief 642WP2 90 degree elbow connect to?
It is a 1/2 inch by 1/2 inch elbow, so both ends take standard 1/2 inch PEX-a tubing. It is not a reducer, so for a change of size you need a different fitting.
2) Does a plastic PEX elbow restrict flow compared to a brass one?
The 642WP2 is a full-flow design, meaning there is no internal bore restriction at the 90 degree bend, so water passes at the same rate as the straight 1/2 inch PEX run. That is the main reason plumbers reach for a poly expansion elbow over a reduced-bore fitting when they have several direction changes on one branch.
3) Can I use the 642WP2 elbow behind a wall or under a slab-level floor cavity?
Yes for concealed behind-the-wall, under-floor, and mechanical chase rough-in, which is what the molded plastic body is intended for. It is a rough-in fitting, not a finished trim or exposed-fixture connection.
4) Why use a 90 degree PEX elbow instead of just bending the tubing around the corner?
In tight framing cavities a hand bend can kink, and a kinked PEX wall restricts flow and can be damaged over time. The 642WP2 gives a clean 90 degree direction change inside the stud bay without relying on the tube's bend radius. On wide-open runs where you can hold a gentle sweep, the tubing itself is fine and no fitting is needed.
5) How is the Sioux Chief 642WP2 elbow packaged for contractors and distributors?
It ships in bulk at 625 each per case, which suits shops stocking 1/2 inch PEX rough-in across multiple jobs rather than someone needing a handful of fittings.
