Featuring a closed air bladder and stainless steel connections, it ensures safe, contaminant-free water delivery on demand. Compact and NSF/ANSI certified, this USA-made tank fits under your sink for convenient, reliable hydration. ## Description iSpring T32M 3.2 Gallon Pressurized Storage Tank for Reverse Osmosis (RO) Systems The reverse osmosis process is on the slower side, so a pressurized storage tank is typically required to supply water from the system on demand. Your RO system will fill the T32M tank to capacity, and when you open your RO water dispenser the water is sent out by the tank's pressurized air bladder. The concern that pollutants may be allowed in when using an open air tank favors the use of a closed expansion tank such as the T32M. The tank uses stainless steel connections to avoid any leaching concerns, tested by independent third-party to meet NSF/ANSI Standard. ## Features - RO ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B00439MYYE | | Brand Name | iSpring | | Capacity | 3.2 Gallons | | Container Type | Dispenser | | Country Of Origin | USA | | Customer Reviews | 4.6 4.6 out of 5 stars (4,532) 4.6 out of 5 stars | | Global Trade Identification Number | 00662425023684 | | Installation Type | Under Sink | | Item Weight | 3.63 kg | | Lowertemperature Range | 40 Degrees Fahrenheit | | Manufacturer | iSpring | | Manufacturer Part Number | T32M | | Model Name | Kit 1 | | Model Number | FT32M | | Number Of Items | 1 | | Number Of Packs | 1 | | Other Special Features Of The Product | RO | | Power Source Type | Corded Electric | | Purification Method | Reverse Osmosis | | Supported Water Tds Level Maximum Ppm | 500 | | Unit Count | 1.00 Count | | Upc | 662425023684 | ## Product Details - **Brand:** iSpring - **Special Feature:** RO - **Capacity:** 3.2 Gallons - **Package Information:** Dispenser - **Installation Type:** Under Sink ## Images ![iSpring T32M 4 Gallon Residential Pre-Pressurized Water Storage Tank for Reverse Osmosis (RO) Systems - Image 1](https://m.media-amazon.com/images/I/51GBWLclIKL.jpg) ![iSpring T32M 4 Gallon Residential Pre-Pressurized Water Storage Tank for Reverse Osmosis (RO) Systems - Image 2](https://m.media-amazon.com/images/I/71-lWKH5aYL.jpg) ![iSpring T32M 4 Gallon Residential Pre-Pressurized Water Storage Tank for Reverse Osmosis (RO) Systems - Image 3](https://m.media-amazon.com/images/I/71F495NElaL.jpg) ![iSpring T32M 4 Gallon Residential Pre-Pressurized Water Storage Tank for Reverse Osmosis (RO) Systems - Image 4](https://m.media-amazon.com/images/I/71aGlj+pR+L.jpg) ![iSpring T32M 4 Gallon Residential Pre-Pressurized Water Storage Tank for Reverse Osmosis (RO) Systems - Image 5](https://m.media-amazon.com/images/I/716+5a0T8-L.jpg) ## Available Options This product comes in different **Set name** options. ## Questions & Answers **Q: Can I connect 2 tanks together for more water storage?** A: I put two 3.2 gal tanks together with a tee last month. It works fantastic!! **Q: Anyone know if this will work for Whirlpool RO systems? The support rep told me any RO tank would work. Anyone use this for another system?** A: I don't think it matters what RO system you have. If it has the option for a reserve tank and the fitting works, then it should fill with water. **Q: What is the pressure rating for the tank. Can it handle 60 psi?** A: Remember that the RO system water valve regulates the "internal" pressure, so the tank is not going to see the actual water line pressure. Most valves operate at 65%, so if your water line pressure is 60 psi, the pressure at the tank generally won't be more than 40 PSI. In most setups you'd need the pressure on the water line to be around 92 PSI to get 60 PSI on the tank. **Q: What is the diameter of the 5.5 gal tank?** A: Thanks for the question! The diameter of the tank is 12" x 16" (H) Kindest, iSpring Team ## Customer Reviews ### ⭐⭐⭐⭐⭐ Top verarbeitet – Perfekte Größe für kleine Haushalte! *by on Reviewed in Germany 30 April 2026* Wer eine zuverlässige Speicherlösung für seine Umkehrosmoseanlage sucht, trifft mit dem iSpring T32M eine sehr gute Wahl.Meine Eindrücke:Ideale Kapazität: Die 12 Liter (3.2 Gallonen) Bruttovolumen sind absolut ausreichend für den täglichen Bedarf.
