2.1-Gallon Non-Potable Water Expansion Tank

This non-potable water expansion tank is for commercial and residential closed-loop hydronic heating systems. It helps heating-system installers and maintenance teams manage hot-water thermal expansion and maintain system pressure below the relief valve setting.

The carbon steel tank has an epoxy finish, a 2.1-gallon volume, and a 12 PSI pre-charge. Its expansion membrane and butyl diaphragm keep water separated from air in the tank. It connects to supply piping with a 1/2-inch MNPT connection and includes a 0.302-32 charging valve connection with a standard tire valve. Maximum working pressure is 75 PSI (5.3 bar). Dimensions are 8.5 inches wide, 13.5 inches deep, and 8.5 inches high.

Key Features:

• 2.1-Gallon Capacity: Provides expansion capacity for compatible closed-loop hydronic heating piping.
• 12 PSI Pre-Charge: Provides a pre-charged starting point for system setup.
• Water-Separating Membrane: Prevents water from contacting the air inside the tank.
• Butyl Diaphragm: Helps minimize air-charge loss in the system.
• 1/2-Inch MNPT Connection: Connects directly to compatible supply piping.
• Standard Tire Valve: Allows on-site tank charging to meet system requirements.

Choose this 2.1-gallon expansion tank for non-potable, closed-loop hydronic heating applications that require a 1/2-inch MNPT supply-piping connection and on-site charge adjustment.
