Viessmann 7826553 Gasket
The Viessmann 7826553 Gasket (Flue Gas) is an essential internal sealing component engineered specifically for high-efficiency condensing boilers and heating systems. As a critical OEM replacement part, this 110mm gasket is designed to create an airtight, leak-proof barrier within the flue exhaust system, preventing the migration of combustion gases into the mechanical room. Fabricated from high-grade, heat-resistant elastomer, it maintains structural integrity under the constant thermal cycling and corrosive condensate conditions typical of Viessmann Vitodens series boilers, including the 200-W and 300-W models.
For service technicians performing annual maintenance or emergency repairs, the Viessmann 7826553 ensures optimal combustion performance by maintaining precise backpressure within the heat exchanger assembly. High-temperature resistance prevents the material from becoming brittle or deforming, which is vital for long-term flue system sealing. This gasket is also compatible with Skoberne flue components, providing a versatile solution for commercial HVAC maintenance and residential boiler service. Ensure all mating surfaces are clean of debris before installation to achieve a primary seal and maintain rigorous safety standards.
Key Benefits:- Precision Flue Sealing: Maintains a secure, airtight connection to prevent hazardous flue gas leaks.
- Thermal Resiliency: Constructed from high-stability elastomer to withstand extreme exhaust temperatures without degradation.
- OEM Compatibility: Exact fit for Viessmann Vitodens 200-W and Vitodens 300-W cascading and system boilers.
- Corrosion Resistance: Engineered to resist the acidic nature of flue gas condensate in condensing heating applications.
- System Efficiency: Helps maintain appropriate draft and combustion parameters for peak fuel economy.
- What is the diameter of this gasket? This specific part features a 110mm diameter, standard for large-scale Viessmann flue gas assemblies.
- Can this be used on the air intake side? No, the 7826553 is specifically designed for the flue gas exhaust side; air intake gaskets usually have different diameter and material specifications.
- When should this gasket be replaced? It should be inspected during every annual service and replaced immediately if any signs of compression set, cracking, or hardening are observed.
