Watts-FRO-122-WH Metal Tank for RO Storage, 10" x 15", 3.2 Gallon Capacity, 1/4" IN NPT, White
Watts FRO-122-WH 3.2 Gallon Pressurized Storage Tank
Metal pressure tank with virgin polypropylene liner and high-grade chlorobutyl diaphragm for reliable reverse osmosis water storage
The Watts FRO-122-WH is a compact 3.2 gallon capacity pressurized storage tank engineered for under-sink reverse osmosis systems. Measuring 10" diameter x 15" height, it features deep-drawn steel domes with precision weld seams, a patented stainless steel water connection, and a 1/4" NPT inlet for standard RO system integration. The high-grade chlorobutyl diaphragm keeps stored water separate from the pressure chamber while maintaining consistent delivery pressure.
Built for Durability and Safety
Virgin Polypropylene Liner
Food-grade liner prevents contamination and ensures stored water remains pure between dispense cycles
Deep Drawn Steel Construction
Precision welded seams and steel domes provide structural integrity and long-term reliability under pressure
Post-Cured Diaphragm
High-grade chlorobutyl diaphragm is post-cured to eliminate harmful materials, with smooth construction to prevent abrasion
Sealed Brass Air Valve
O-ring sealed air valve cap and brass valve body ensure the air chamber remains leak-free for consistent pressure
Stainless Steel Connection
Patented stainless steel water connection resists corrosion and provides secure attachment to RO system tubing
Durable Finish
Two-part primer and polyurethane paint system protects exterior from moisture and wear in under-sink environments
Universal RO System Integration
The Watts FRO-122-WH is compatible with most residential reverse osmosis systems using standard 1/4" quick-connect or NPT fittings. Designed for under-sink installation with compact 10" x 15" footprint. Works with Watts Premier, APEC, iSpring, Home Master, and other branded RO systems requiring 3-4 gallon storage capacity. Pre-charged and ready to install—no maintenance required during service life.
Watts has been manufacturing pressure vessels and water treatment components for residential and commercial applications for decades, with NSF certification backing their commitment to safe drinking water storage.
