It includes two pre-installed 1/4-turn lead-free chromed angle stops for hot and cold water supply. It complies with NSF 61-G portable water standards. Choose this if you need a ready-to-install water outlet with compliant components. Limitation: it is designed for faucet connections, not gas lines.
Sioux Chief 696-1021GF Ox Box Gas Outlet Box
Sioux Chief offers a gas outlet box suitable for ½” or ¾” iron-pipe applications or ½” CSST, with a ¼-turn ball valve for easy operation. The recessed ABS box is designed for strong installations across standard and fire-rated products. Best for projects requiring multiple-pipe compatibility and a robust recessed design. The box is heavier and may require precise cutting for perfect fit in some installations.

Buying Guide: Key Considerations When Choosing Supply Valve Outlet Boxes
What installation environment are you targeting—gas lines or water supply? Consider valve type, material durability, and compatibility with your piping standards. For gas, look for CSA/ANSI-compliant valves and ABS or steel-reinforced housings. For water, prioritize lead-free components, NSF/ANSI certifications, and easy shut-off access. Recessed versus surface-mounted designs affect finish and accessibility. In mixed-use spaces, choose boxes that clearly state dual compatibility or provide separate gas and water options.
Valve Type And Certification
Gas outlet boxes should use NPT-threaded valves and meet applicable safety standards (CSA, ANSI). Water outlet boxes should use lead-free, compliant valves with NSF/ANSI certifications. Ensure the valve type matches your pipe sizing (1/2″, 3/8″ compression, etc.).
Material And Durability
High-impact ABS bodies offer rigid engagement and resistance to impact, moisture, and chemicals. For fire-rated environments, check product listings for appropriate ratings and compatibility with fire-rated assemblies.
Inlet And Outlet Compatibilities
Check inlet types (Pex, Crimp, Barb) and outlet configurations (compression, 1/4-turn ball valves). Ensure the box supports the required piping standards (Pex F1807 for ice makers, CSST vs iron-pipe for gas).
Installation Fit And Accessibility
Recessed boxes provide a cleaner look, but require precise framing. Faceplate designs should allow easy access for shut-off and maintenance. Verify rough opening dimensions to avoid rework on site.
Best For Scenarios
- Gas-focused projects: VN Infinite quality, Sioux Chief, HYDRO MASTER offer robust gas-facing components and varied inlet options.
- Water-focused installations: EFIELD faucet and ice maker boxes provide ready-to-install, pre-assembled water outlets with integrated shutoffs.
- Combined or flexible installations: Choose products that advertise versatile inlet types or mixed-use capabilities and confirm compatibility with your local code requirements.
Installation Tips
Plan the line runs to minimize bending and avoid sharp corners near the valve. Pre-check all required mounting hardware and ensure proper sealants or thread tapes are used according to the material and valve type. Have a certified professional review critical gas connections when in doubt.
