From the Manufacturer This Thermal Expansion Tank prevents hot water from back flowing into the cold water line. This tank also prevents hot water from escaping through the pressure relief valve and onto the floor. The thermal expansion tank prevents constant fluctuations in water pressure that damage the heater. Review: good product - Easy install; worked just fine Review: Nice price and easy to use/install. - Easy to install based on my plumbing. I installed upside down on the cold water inlet to my tankless. Charged it to the incoming static water pressure (65psi). Turned the water on and now when I turn on my cold water in the kitchen in the morning, it is no longer warm. Two+ years later, I installed a 2 gal POU water heater for my whole-house humidifier since the humidifier wouldn't activate the whole house (a good thing). Noticed the cold water from the kitchen faucet getting warm again. Checked the expansion tank pressure and it was low so I recharged to 65 psi. ## Features - alloy steel - Imported - WATER HEATER PROTECTION: Prevents excess pressure caused by thermal expansion in water heater systems - DURABLE CONSTRUCTION: Built with a butyl rubber diaphragm and 304 stainless steel system connection - PRE-CHARGED: Factory pre-charged at 40 PSI for reliable performance and ease of installation - SPECS: 4.5 gallon capacity; rated up to 150 PSI and 210 degrees F; 3/4 in MIP connection - WARRANTY: Backed by a 6-year limited warranty for added reliability ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005E83Z4G | | Best Sellers Rank | #141,663 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #269 in Water Heater Replacement Parts #22,753 in Parts & Accessories | | Brand Name | Eastman | | Capacity | 2 Gallons | | Color | White | | Customer Reviews | 4.7 4.7 out of 5 stars (685) | | Global Trade Identification Number | 00091712600237 | | Included Components | Electrical & Heating;Door Chimes;doorbell-push-buttons | | Is Electric | No | | Item Depth | 11.5 inches | | Item Dimensions W x H | 11.1"W x 16"H | | Item Type Name | Det-12 Thermal Expansion Tank, 4.5 Gal, 3/4 In Mpt, Steel | | Item Weight | 5.2 Pounds | | Manufacture Year | 2023 | | Manufacturer | EZ-FLO | | Manufacturer Part Number | 60023 | | Material Type | Rubber | | Maximum Pressure | 150 Pound per Square Inch | | Maximum Temperature | 210 Degrees Fahrenheit | | Model Number | 60023 | | Mount Type | Wall | | Power Source | hand_powered | | Special Features | Thermal Expansion | | Style Name | Indoor Installation | | UPC | 091712600237 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Eastman - **Capacity:** 2 Gallons - **Power Source:** hand_powered - **Product Dimensions:** 11.1"W x 16"H - **Special Feature:** Thermal Expansion ## Images ![Thermal Expansion Tank, 4.5 gal, 3/4 in MIP Connection, 60023 - Image 1](https://m.media-amazon.com/images/I/610HT8g-DrL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: is this for patable water?** A: Yes, this for use with potable water. **Q: Is this for a 50 gallon tank?** A: If your water pressure is below 70 PSI, this tank will work. If it is 80 PSI, you will need the larger 4 gallon model. Refer to this guide http://media.wattswater.com/pg-thermexpansion.pdf/. **Q: Do i need this if my boiler has one and water heater is close by** A: Heating boiler piping system is typically isolated from the water piping system for the rest of the house (such as by a pressure reducing or check valve to drop the house water pressure of ~ 60 psi to the typical less than 20 psi of the heating boiler side). Therefore the heating boiler expansion tank function would not effect the hot water boiler thermal expansion. Heating boiler thermal expansion tanks are typically factory charged to 12 psi while those for hot water tank are charged to 40 psi. ps I am not a professional so you may want to do more research of your own. **Q: is this a suitable replacement for the Amtrol Extrol 2 gallon ?** A: Yes it a suitable replacement. ## Customer Reviews ### ⭐⭐⭐⭐⭐ good product *by D***N on November 18, 2025* Easy install; worked just fine ### ⭐⭐⭐⭐⭐ Nice price and easy to use/install. *by J***D on November 1, 2025* Easy to install based on my plumbing.
