AY McDonald 6127373 16002-V3MPX DURAMAC HYDRONIC EXPANSION & POTABLE WATER TANKS, 2 GALLON, 3/4 MIP DuraMAC Expansion Tanks are designed for the specific purpose of accomodating the natural expansion of water in a Hydronic Heating System. To eliminate the water logging that is trouble-some but normal in a plain steel expansion tank, the air and water within the tank is permanently separated by a butyl diaphragm. The In-Line series are light in weight, easy to install, and afford many years of trouble-free service. DuraMAC Expansion Tanks eliminate wasting water and provide a smooth operating system. With a unique lining on the water side, you are assured long trouble-free service.
