9 x 48 Black Mineral Tank – 2.5″ Top Opening with Base

The 9″ × 48″ Black Mineral Tank provides a durable vessel for water softening, ion exchange, activated-carbon filtration, and other residential or light-commercial water-treatment applications. Its 9-inch-diameter, 48-inch configuration is commonly used in systems designed around approximately one cubic foot of treatment media, subject to the media type, required freeboard, and equipment design.

A standard 2.5-inch top opening provides an interface for compatible control valves, adapters, distributors, and other water-treatment components. This makes the tank suitable for new equipment assemblies as well as replacement applications where the valve thread, riser tube, distributor, pressure rating, and overall dimensions have been confirmed.

The black exterior offers a clean, professional appearance while shielding the internal contents from ambient light. An integrated support base helps maintain the vessel in an upright position during normal installation and operation.

Depending on the verified manufacturer, tanks in this category commonly use a seamless polyethylene inner liner surrounded by fiberglass composite reinforcement. This construction combines corrosion resistance with the structural strength needed for pressurized water-softening and filtration systems.

The tank may be used with ion-exchange resin, activated carbon, catalytic carbon, neutralizing media, and other compatible treatment media. Media selection, loading volume, freeboard, backwash requirements, operating pressure, and chemical compatibility must be determined by the system designer.
