Advantages of a metal diaphragm Type expansion tank. Metal shell has greater pressure resistance than plastic. lower molecular porosity of metal eliminates air pressure loss. diaphragm-type design assure stable water outflow. Features:. stainless steel connection built for reverse Osmosis water storage tank; pump tank and thermal tank applications. Brass cap with internal O-Ring guarantees no air loss from air-vent. smooth internal air vent cap prevents diaphragm damaged. high-grade butyl diaphragm, post-cure procedure insures a tasteless and odorless water chamber.
