Description
The Zilmet ZEP12 In-Line Thermal Expansion Tank features a 3/4″ NPT connection stainless steel construction, and 4.8-gallon capacity for managing pressure changes in closed water circulation systems. Built to absorb excess water expansion created during heating cycles, the tank helps reduce stress on connected plumbing and system components. Commonly used into boilers, water heating equipment, and circulation assemblies associated with HVAC systems, it supports stable pressure regulation during operation. Connected inline with compatible piping during installation or replacement procedures, the expansion tank helps minimize pressure fluctuations and maintain balanced water flow throughout the system.
