The WEBER HUFF 110-254F is a 1.5-inch flange set used to secure and connect piping in hydronic heating and plumbing systems. Flange sets provide a leak-resistant mechanical connection point between pumps, valves, or other inline components and the surrounding pipework. This type of fitting is a standard component in closed-loop and open-loop hydronic systems and is typically installed by licensed plumbers or HVAC technicians during system commissioning or service work.
The 110-254F flange set is suited for residential and light commercial hydronic heating applications where 1.5-inch pipe connections are required. It is commonly used at circulator pump unions, boiler connections, and zone valve installations. Flange sets allow for easier pump removal and reinstallation without cutting into the piping system.
Designed as an OEM-style replacement flange set for 1.5-inch hydronic heating system connections.
Installation is typically performed by a licensed plumber or HVAC technician. Shut down the boiler or hydronic system and allow it to cool before beginning any flange work. Drain the affected piping section to prevent water release during disassembly. Follow IPC and local plumbing codes for flange torque sequencing and gasket installation practices.
