Amtrol (143-132) RO Steel Pressure Tank 10.3 Gallon 3/4" NPT Blue
Amtrol 143-132 RO Steel Pressure Tank 10.3 Gallon 3/4" NPT
The original inventor of RO tank technology delivers four decades of engineering excellence in pressurized water storage. American-made diaphragm design for maximum capacity and water purity.
Pioneer diaphragm technology with fully enclosed water reservoir
Enclosed Polypropylene Reservoir
Fully enclosed butyl and polypropylene diaphragm provides superior water purity with minimal rubber contact compared to traditional bladder tanks. Water never touches metal surfaces.
Maximum Water Discharge
Amtrol's original diaphragm design delivers 6.6 gallons of usable capacity from 10.3 total gallons. More complete discharge means better turnover and fresher stored water.
Steel Construction
Durable painted steel shell with corrosion-resistant coating. 3/4" NPT fitting provides compatibility with most residential and light commercial RO systems.
Four Decades of Engineering
Amtrol invented RO tank technology and holds the patents. This isn't a look-alike copy. It's the original design refined through 40 years of manufacturing experience.
