Bard part number 1921-037 is an OEM flue or smokepipe gasket used on Bard gas heating sections to seal the vent connection so combustion byproducts stay in the flue path and the unit maintains proper draft. If your existing gasket is brittle, compressed, or leaking around the flue collar, replacing it with the correct Bard gasket helps prevent nuisance shutdowns and protects nearby components from heat and flue gas leakage. This gasket is commonly referenced as a smokepipe gasket with an inside diameter around 5.875 inches, so confirm your model and flue outlet size before ordering to ensure proper fit.
* Orders less than $50 may incure a minimum order fee.
