The Flexcon Expansion Water Tank HTX 30FV includes a fill valve and is constructed of deep drawn welded steel domes that carry a capacity of 4.5 gallons of water. It features diaphragms constructed of butyl rubber that is engineered for a longer life offering low permeability rates at higher temperatures. The oversized diaphragm maximizes tank drawdown, minimizes wear and eliminates diaphragm stretch, all of which enhance the tank's longevity. This tank utilizes a welded system connection with a built-in hex nut for easy, hassle-free installation and the brass shredder valve includes an o-ring seal ensuring air side integrity minimizing leaks. The appliance quality finish on the outside of the tank provides many years of service within damp basements or crawl spaces. Every Flexcon Hydronic Expansion Tank is pressure tested and backed with a 5 Year Written, Limited Manufacturer's Warranty. Each package includes the tank, an air scoop and vent for added installer convenience.
