Sioux Chief 598-023 Heavy-Duty Expansion Tank Mounting Bracket with Arm, Leg & Foot

Sioux Chief 598-023 Heavy-Duty Expansion Tank Mounting Bracket with Arm, Leg & Foot

The Sioux Chief 598-023 is a heavy-duty (H.D.) tank mount bracket engineered to support expansion tanks behind the wall or in the mechanical room. The bracket ships as a complete assembly with a mounting arm, leg, and foot, and is sized to handle both 2-gallon and 5-gallon expansion tanks in either vertical or horizontal installations. Rather than letting a filled expansion tank hang unsupported on its water connection, the 598-023 transfers the tank's weight to the wall or floor framing, keeping strain off the supply piping and fittings. It is built and packaged for professional rough-in plumbing crews working new construction or tank replacement jobs.

Key Features

• Heavy-Duty Bracket Construction: H.D. design built to carry the weight of a filled expansion tank without sagging, flexing, or loosening over time.
• Complete Arm, Leg & Foot Assembly: The mounting arm cradles and secures the tank, the leg extends support down to the mounting surface, and the foot provides a stable base point, giving installers a full support system in one part.
• Vertical or Horizontal Mounting: The bracket accommodates both vertical and horizontal expansion tank orientations, so it fits a wider range of mechanical room and rough-in layouts.
• Dual Tank Capacity Compatibility: Sized to properly support both 2-gallon and 5-gallon expansion tanks, covering the two most common residential and light-commercial tank sizes.
• Reduces Strain on Supply Piping: By carrying the tank's weight independently, the bracket helps prevent stress on the water connection and surrounding pipe joints.
• Made in the USA: Manufactured in the United States for consistent fit, finish, and dimensional accuracy from carton to carton.
