Bard part number 8603-032 is an OEM replacement O-ring used to restore a proper seal in select Bard HVAC refrigeration and service connections where a leak-tight fit is critical for maintaining system pressure and preventing refrigerant or oil seepage. If you are servicing a Bard wall-mounted air conditioner or heat pump and you have a disturbed fitting or a connection that will not hold pressure, replacing the O-ring with the correct Bard-specified part helps ensure reliable sealing and proper system operation. Confirm placement and size by matching the original O-ring from your unit’s parts breakdown before ordering, since O-rings can be used in multiple locations depending on model and revision.
* Orders less than $50 may incure a minimum order fee.
