Weil-McLain Boiler Parts Finder Tool

Weil-McLain boilers are widely used in hydronic heating systems, and replacement parts need to match the exact model. The fastest way to avoid ordering the wrong igniter, sensor, gasket, or control component is to start with the full model number from the boiler's rating plate.

SupplyHouse carries Weil-McLain replacement parts for supported models, including common service items like igniters and ignition kits, maintenance kits, sensors, controls, and gauges.
