This compact flat-round hydronic expansion tank helps stabilize pressure fluctuations in closed heating systems, protecting boilers, piping, and valves from stress. The 4.8-gallon capacity is well-suited for residential hydronic loops and small commercial setups. A built-in union with two-way check valve simplifies installation and servicing, while the welded mounting bracket ensures secure placement. Durable internal diaphragms maintain long-term reliability.
