Watts-FRO-132-WH Metal Tank for RO Storage, 12 IN x 16 IN, 4 Gallon Capacity, 1/4 IN NPT, White
Watts-FRO-132-WH 4 Gallon Metal RO Storage Tank
The Watts-FRO-132-WH replaces or upgrades reverse osmosis storage on most standard under-sink RO systems. Its compact 12-inch by 16-inch footprint fits tight spaces while the high-grade chlorobutyl diaphragm and deep-drawn steel construction ensure long-term reliability without maintenance.
Virgin Polypropylene Interior
Food-grade liner ensures no chemical leaching or contamination of stored RO water. Post-cured diaphragm removes residual materials before first use.
High-Grade Chlorobutyl Barrier
Separates stored water from pressurized air chamber. Smooth internal construction prevents abrasion and extends service life without periodic replacement.
Patented Stainless Steel Fitting
Corrosion-resistant water connection with 1/4-inch NPT threads. Sealed brass air valve with O-ring cap maintains consistent pressure without leaks.
Deep-Drawn Steel Shell
Precision-welded seams and two-part primer with white polyurethane finish. Deep-drawn domes resist corrosion and maintain structural integrity under pressure.
The Watts-FRO-132-WH uses industry-standard 1/4-inch NPT threading and fits most residential reverse osmosis systems from Watts, APEC, iSpring, Home Master, and other manufacturers. The 12-inch diameter and 16-inch height work in typical under-sink cabinets with at least 18 inches of clearance. Pre-charged air pressure should be checked and adjusted to 7-8 psi before installation for optimal flow delivery.
