Bard part number 171-202 is an OEM heat exchanger used in Bard DCC050 and DCC065 gas furnace units, where it transfers heat from the burner side into the supply airstream to deliver safe, consistent heating performance. If your furnace has a cracked, leaking, or corroded exchanger, replacing it with the correct Bard heat exchanger helps restore proper combustion isolation, heat output, and overall reliability without guesswork on fit. Confirm compatibility by matching the full unit model and serial number on the nameplate and referencing the DCC series parts documentation before ordering, since DCC revisions can change component usage.
* Orders less than $50 may incure a minimum order fee.
