Sioux Chief 696R2313XF Fire-Rated Washing Machine Outlet Box with PEX F1807 Connections & Water Hammer Arrester

Sioux Chief 696R2313XF Fire-Rated Washing Machine Outlet Box with PEX F1807 Connections & Water Hammer Arrester

The Sioux Chief 696R2313XF is a fire-rated OxBox washing machine outlet box built for behind-the-wall laundry rough-in, combining PEX F1807 crimp supply connections, a factory-integrated water hammer arrester, and a mounting frame in a single assembly. Designed for installation in fire-rated wall assemblies, this outlet box gives a plumber one code-focused location to set the washing machine hot and cold supply along with the drain connection during rough-in, then close the wall around it at finish. The built-in arrester is positioned to absorb the pressure surge created when a washing machine solenoid valve closes, helping quiet water hammer noise in the branch supply lines feeding the laundry connection. Manufactured in the United States, this OxBox ships as a complete rough-in unit ready to set, crimp, and frame into the wall cavity.

Key Features

• PEX F1807 Crimp Connections: Supply connections are configured for ASTM F1807 PEX crimp-ring fittings, matching standard rough-in crimp installation practice for hot and cold laundry supply lines.
• Fire-Rated Construction: Rated for installation in fire-rated wall assemblies, supporting laundry rough-in work where the wall penetration must maintain its fire rating.
• Integrated Water Hammer Arrester: A factory-installed arrester on the box absorbs the pressure spike generated when a washing machine solenoid valve closes, reducing pipe hammer and noise in the supply lines.
• Includes Mounting Frame: Ships with a frame for setting and squaring the box in the wall cavity during rough-in, ahead of drywall and finish work.
• OxBox Washing Machine Outlet Box: A purpose-built outlet box consolidates the hot and cold supply stops and the drain connection behind a single wall-plate location for the laundry appliance.
• Single-Trip Rough-In: Combining the supply connections, arrester, and frame in one box reduces the number of separate rough-in components a plumber has to set and align.
