Product description

The Hopper Throat Gasket is a critical safety and efficiency component for Harman pellet stoves, sealing the transition area where pellets move from the storage hopper into the feeder system. This gasket serves two primary functions: it prevents moisture from entering the pellet feed system from the hopper and, more importantly, it ensures an airtight seal that prevents smoke or combustion gases from back-venting into the fuel storage area. A compromised hopper throat gasket can lead to fuel jams due to swollen pellets or can trigger safety sensors that shut the stove down. Constructed from durable, fire-retardant gasket material, this replacement ensures that your stove remains pressurized correctly and that your fuel supply stays dry and ready for combustion. Replacing this gasket is a simple but effective way to ensure the long-term reliability of your stove's fuel delivery mechanism.

Product highlights

• Safety Sealing: Prevents smoke and dangerous gases from migrating into the pellet hopper.
• Moisture Barrier: Helps keep pellets dry at the throat of the hopper to prevent swelling and feeder jams.
• Airtight Performance: Ensures the feeder system maintains the vacuum pressure required for modern stove safety sensors.
• OEM Fitment: Designed to the exact specifications of Harman hopper throat geometries for a perfect seal.
• High-Temperature Resistance: Built to withstand the proximity of the combustion chamber without hardening or cracking.
