Replacement silicone docking gasket for all Harman pellet stove inserts. Older versions of this gasket were red in color, this is the replacement for that gasket.
The docking gasket is the main seal between the insert and the flue vent. When the insert is pushed back into the frame, this is the gasket that seals the venting to the unit. If you are noticing ash and soot in and around the back of the unit when cleaning or if you are experiencing soot collecting in the room around the front of the stove, there’s a good chance that this gasket is not making a tight seal.
This gasket comes with an adhesive backing.
