Eastman 60022 Potable Water Thermal Expansion Tank 2.1 Gallon with 3/4" MIP Connection

Product Description

The Eastman 60022 Thermal Expansion Tank is designed to protect residential potable water systems from excessive pressure caused by thermal expansion during water heater operation. With a 2.1-gallon capacity, this expansion tank absorbs the increased water volume created as water heats, helping prevent damage to water heaters, plumbing, fixtures, and pressure relief valves. It is recommended for use in closed-loop water supply systems and is compatible with gas, electric, and oil-fired residential water heaters.

Constructed with a durable drawn steel tank, a food-grade chlorobutyl diaphragm, and a corrosion-resistant triple-coated epoxy finish, the Eastman 60022 is built for long-lasting performance. The tank is factory pre-charged and features a field-adjustable air charge to match system pressure for optimal operation.
