Sioux Chief 696RG Oxbox No-Lead Fire-Rated Washing Machine Outlet Box
The Sioux Chief 696RG Oxbox is a no-lead, fire-rated washing machine outlet box system built for rough-in installation behind the wall ahead of laundry appliance connections. This family of outlet boxes pairs durable ABS supply and drain boxes with a built-in water hammer arrester to absorb pressure spikes caused by quick-closing solenoid valves in washing machines, and is available in a choice of supply connection types to match the rough-in method on the job — F1960, MIP/F, or PEX F1807. The box is Warnock Hersey listed to meet the ASTM E-814 and CAN/ULC S115 fire-rated assembly standards, making it suitable for fire-rated wall applications where the penetration must maintain the wall's fire rating. Separate supply and drain boxes give the installer flexible layout options on the rough-in, and the whole assembly ships ready for stud or between-stud mounting.
Key Features
- Durable Construction: ABS supply and drain boxes resist cracking and corrosion typical of rough-in wet-wall environments.
- Quarter-Turn Ball Valves: Fast, reliable shutoff for hot and cold supply lines feeding the washing machine.
- Connection Options: Available in F1960, MIP/F, or PEX F1807 supply connections to match the piping method used on the rough-in — select the option that fits your job.
- Integrated Water Hammer Arrester: Dampens pressure surges generated by quick-closing washing machine solenoid valves, protecting the supply piping from hammering noise and stress.
- Separate Supply & Drain Boxes: Independent boxes allow the installer to configure layout to fit framing and appliance placement rather than being locked into a single combined footprint.
- Debris Covers Included: Protective covers shield the box interior from dust, mud, and paint overspray during the rough-in and finish phases of construction.
- Removable Test Cap: The drain box test cap removes easily with pliers for pressure testing before the wall is closed up.
- No-Lead Compliant: Meets Prop 65 lead-content requirements, referenced in the manufacturer's compliance documentation as Prop 82.

Why Sioux Chief?
Sioux Chief builds the Oxbox outlet box family with durable ABS construction, quarter-turn ball valves, and an integrated water hammer arrester so plumbers can complete a code-oriented laundry rough-in with fewer callbacks for hammering pipes, choosing whichever of the F1960, MIP/F, or PEX F1807 connections fits the job. The Warnock Hersey listing to ASTM E-814 and CAN/ULC S115 supports use in fire-rated wall assemblies, and the no-lead compliance reflects Sioux Chief's attention to current plumbing material requirements across every connection option in this family. Installers appreciate having separate supply and drain boxes on the 696RG Oxbox, since it lets the rough-in layout adapt to framing constraints instead of forcing a single fixed footprint, and the included debris covers keep the box clean through drywall, mudding, and paint before the washing machine is ever connected.
