Wessels 125psi 1-1/2in NPT Bladder Expansion Tank

The Wessels 125 PSI 1-1/2in NPT Bladder Expansion Tank is designed for thermal expansion control and pressure stabilization in hydronic heating and water systems. Designed for inline plumbing installations, this bladder-type tank uses a 1-1/2 inch NPT threaded connection and is rated for 125 PSI, making it suitable for steady pressure regulation in commercial equipment used in heating and water systems. Applications include thermal expansion control, water pressure stabilization, hydronic heating operation, and boiler system support in HVAC and commercial plumbing installations. Commonly installed in HVAC systems, boiler assemblies, and other commercial plumbing equipment requiring reliable fluid expansion management, it supports system stability across cycling loads. Heavy-duty construction supports continuous operation in commercial fluid pressure systems, and it is a common replacement option alongside Amtrol Extrol Expansion Tank, Bell & Gossett Expansion Tank, and Taco Hydronic Expansion Tank. Industrial usage centers on commercial fluid pressure systems where reliable pressure control is essential.
