Peerless boilers are common in hydronic systems, and the parts support is deep—but replacement parts still need an exact model match. A gasket, ignitor, or control that fits one Peerless series can be the wrong part for another.

SupplyHouse carries Peerless boiler replacement parts for supported models, including gaskets, gauges, switches, ignitors, flame sensors, and control kits. You'll also find maintenance kits that bundle multiple service items for specific boiler families (like PUREFIRE).

Enter the model number exactly as printed on the boiler rating plate. Matching the complete model number is the quickest way to avoid ordering the wrong gasket, ignitor, flame sensor, or control component.
