Utica-Dunkirk 1580006 Air Purge 328140-751 The Bard 8403-062 is aThe Utica Dunkirk 1580006 Air Purge is a vital component for maintaining the hydraulic integrity of residential and commercial boiler systems. Engineered for high efficiency air removal, this 1 8" NPT vent air purge effectively eliminates trapped pockets of air that cause pump cavitation, reduced heat transfer, and system "banging" or gurgling. As a field proven boiler air vent replacement, this part ensures the circulatory loop remains pressurized
