COMPATIBILITY & APPLICATIONS
Where the PAE RO-132 Fits

This metal pressure tank is designed for residential under-sink reverse osmosis systems where a 4-gallon storage capacity is needed. The 1/4" NPT threaded connection is standard across most household RO units, making the RO-132 a direct replacement or upgrade for older atmospheric or bladder tanks. The pre-pressurized design eliminates the need for a booster pump in typical municipal water applications, delivering steady flow to your RO faucet. Suitable for new installations or as a replacement tank in existing PAE, APEC, iSpring, or other compatible RO systems. The powder-coated steel shell resists corrosion in humid under-sink environments, and the butyl diaphragm keeps stored water isolated from air to reduce bacterial growth and maintain water quality between uses.

💧 Check your tank's air pressure annually with a tire gauge at the Schrader valve (tank empty). Maintaining 5-7 PSI ensures optimal drawdown and prevents the diaphragm from over-stretching or under-performing.
