Honeywell-KTCOMB25-Flansch-Set

This flange kit, Honeywell KTCOMB25, is a connection set used to join a boiler or burner to its pipework. Parts of this type provide the mechanical interface between the appliance and the gas, water, or condensate lines, ensuring a secure, sealed joint. The kit includes the flanges and the associated hardware – gaskets, bolts, or seals – needed to complete the connection. Flange kits are typically specific to a particular appliance model or series, because the bolt pattern, flange face dimensions, and port arrangement are fixed by the manufacturer. When selecting a flange kit of this class, the primary parameters are the thread type and size (or flange nominal diameter), the sealing method (flat gasket, O-ring, or taper), and the pressure and temperature rating of the application. For boiler-specific sets, the geometry is predetermined, so generic equivalents are rarely interchangeable. The material of the flange must be compatible with the medium (water, gas, condensate) and the operating conditions. During replacement, verify that the flange kit matches the existing mounting points on the appliance and the pipework orientation. Check that all sealing surfaces are clean and undamaged before installation. If the original kit used a specific gasket or O-ring, use the same sealing method to avoid leaks. Torque the bolts to the appliance manufacturer’s specification to prevent distortion.
