Bard part number 1921-049 is an OEM silicone vent terminal gasket used on Bard wall mounted HVAC equipment to seal the vent terminal connection and help prevent flue gas leakage and unwanted air infiltration at the cabinet penetration. Replacing a worn, cracked, or flattened gasket helps restore a tight seal that supports proper combustion venting and reduces the chance of moisture or air leaks around the vent termination. This gasket is intended to match Bard fit and service clearances, so verify your unit model and vent terminal style before ordering to ensure correct application.
* Orders less than $50 may incure a minimum order fee.
