Sioux Chief 696-1021GF CSST Gas Outlet Box with Frame, 1/2" x 1/2" NPT

Sioux Chief 696-1021GF CSST Gas Outlet Box with Frame, 1/2" x 1/2" NPT

The Sioux Chief 696-1021GF is an OxBox gas outlet box built for stubbing out gas appliance connections behind the wall, featuring 1/2" x 1/2" NPT threaded connections on both the supply and outlet sides and a mounting frame for a clean, recessed finish. Designed for use with CSST (corrugated stainless steel tubing) gas piping systems, this box requires a box adapter from the CSST manufacturer to complete the tubing connection into the box. It gives plumbers and gas fitters a dedicated rough-in point for washer, dryer, range, water heater, or fireplace gas appliance hookups without exposed tubing or fittings left sitting proud of the wall surface.

Key Features

• Trade Size: 1/2" x 1/2" NPT connections size the box for standard residential and light-commercial gas appliance stub-outs.
• NPT Threaded Connections: National pipe thread ports on both sides of the box accept standard threaded gas fittings for a secure, leak-tight hookup.
• Frame Included: Ships with a mounting frame so the box sits flush and finished once it is recessed into the wall cavity, rather than left as a bare box.
• CSST-Ready Design: Built to integrate with CSST (corrugated stainless steel tubing) gas piping systems; a box adapter from the CSST manufacturer is required to complete the tubing-to-box connection.
• Recessed Rough-In: Mounts inside the wall stud bay ahead of drywall, keeping the gas stub-out concealed until the appliance connector is run to it.
• Country of Origin: Manufactured in Taiwan.

Why Sioux Chief?

Sioux Chief builds its OxBox gas outlet boxes with an integrated frame for a secure, recessed rough-in that gas fitters can count on behind the finished wall, rather than a loose box that shifts before drywall goes up. The 1/2" x 1/2" NPT connections and CSST-ready design give installers a straightforward way to bring gas piping to appliance locations, provided the correct box adapter from the CSST tubing manufacturer is used to complete the run. For plumbing and gas contractors standardizing rough-in boxes across a job, the OxBox line gives a consistent, frame-finished stub-out for every gas appliance location on the plan.
