Weil McLain 563-910-031 Gas Valve Flange 1/2" NPT

The Weil McLain 563-910-031 Gas Valve Flange provides a threaded connection interface between a gas valve and compatible fuel-system piping. Its 1/2" NPT threads connect to identical tapered pipe threads to establish the required mechanical connection at the valve assembly. Positioned at the gas valve connection, the flange aligns the adjoining piping with the valve's gas-flow passage. A correctly configured interface in HVAC systems maintains the intended fuel path between the supply line and valve assembly. This threaded connection preserves the specified piping arrangement and supports controlled gas delivery through the connected combustion circuit.
