Lochinvar & A.O. Smith 100208104 Gasket

Lochinvar & A.O. Smith 100208104 Gasket

The Lochinvar & A.O. Smith 100208104 Gasket is a 4" flue gasket kit engineered for high-performance sealing in gas-fired heating appliances. As an essential component for residential and commercial boilers and furnaces, this kit provides the airtight interface required between the appliance flue pipe and the vent connector. Constructed from high-temperature resistant silicone and ceramic materials, it is designed to withstand extreme thermal cycling while preventing the escape of harmful combustion products like carbon monoxide. Proper installation of internal HVAC vent seals is critical for maintaining negative or positive pressure within the venting system, ensuring that all exhaust gases are channeled safely outdoors. This OEM-spec heating equipment part effectively eliminates energy loss at the flue connection, optimizing overall heat transfer and thermal efficiency. This kit serves as the direct replacement for part numbers such as GKT20003 and matches current Lochinvar 100330219 specifications, ensuring exact fitment for contractors performing critical system maintenance or flue repairs.

Key Benefits
  • High-Temperature Durability: Engineered with premium materials to resist degradation from constant exposure to hot exhaust gases.
  • Precision 4-Inch Fit: Designed for an exact match on 4" flue pipes, eliminating the need for field-modified seals or high-temp silicone RTV alone.
  • Combustion Safety: Creates a reliable barrier against carbon monoxide leaks, ensuring the mechanical room remains safe for occupants.
  • Operational Efficiency: Stabilizes airflow and pressure within the venting system to prevent heat loss and optimize appliance performance.
  • OEM Compatibility: Authentic Lochinvar and A.O. Smith replacement part ensures adherence to original equipment safety standards.
Common Questions

Is the 100208104 gasket compatible with specific boiler brands?
Yes, this gasket kit is primarily designed for Lochinvar and A.O. Smith heating systems, though it fits many appliances requiring a standard 4" flue seal kit. Always check your specific model and serial number before installation.

When should a flue gasket be replaced during maintenance?
Technicians should inspect the flue gasket during every annual boiler service. If you observe signs of cracking, brittleness, or discoloration, the seal is likely compromised and requires immediate replacement to prevent exhaust leaks.

Does this kit include all necessary components for a vent seal?
Yes, this 4" flue gasket kit contains the necessary gaskets to secure the flue connection, providing a complete solution for restoring the integrity of the ventilation system.
