RV tankless water heaters rely on proper flue duct sealing to safely vent exhaust gases. Over time, heat cycles degrade the original seal, causing dangerous carbon monoxide leaks and reduced heating efficiency. This Furrion® replacement flue duct seal is precision-engineered to match OEM specifications for 2.4GPM models.
Features
- Heat-resistant material withstands continuous 200°F+ exhaust temperatures
- Precise 2.4GPM compatibility - designed specifically for Furrion tankless models
- Compression-fit design creates airtight seal without adhesives
- 0.12" thickness matches OEM specifications for proper clearance
- Durable silicone construction resists cracking and drying
- Prevents backdrafting by maintaining proper exhaust flow
Unlike universal seals that may not fit correctly, this Furrion-approved part ensures your water heater vents properly. The specialized silicone compound maintains flexibility across temperature extremes while resisting the corrosive effects of combustion byproducts.
Installation takes minutes - simply remove the old seal (which often crumbles during removal) and press the new one into place. No tools required. Restores your system to factory-sealed condition, preventing dangerous exhaust leaks that could trigger CO detectors or reduce heating performance.
