Eastman 60023 Thermal Expansion Tank, Steel, 4.5 Gal, 3/4 In

A thermal expansion tank absorbs the increased volume of water created when water heats up in your water heater. As water temperature rises, it naturally expands, and without a place for that expansion to go, pressure builds in your plumbing system. The Eastman 60023 is a pre-charged steel expansion tank designed for gas, oil, or electric residential water heaters and hot water storage tank applications.

By providing a dedicated space for expanded water, this tank maintains balanced pressure throughout your water supply system, keeping system pressure below the T&P relief valve setting. This protection helps extend the life of your water heater and reduces unnecessary wear on your plumbing.
