The Lochinvar & A.O. Smith 100208768 is a high-performance 2-inch flange gasket engineered for high-temperature sealing applications in commercial boilers and water heaters. Designed for precision fitment, this EPDM flange gasket ensures a leak-proof seal at the heat exchanger or piping interface, preventing pressure loss and protecting the combustion chamber's integrity. Also identified by part numbers GKT2707 and GKT2707K, this OEM component is critical for maintaining the thermal efficiency of commercial water heater parts. Its robust material composition resists degradation from chemical additives and thermal cycling, making it a standard replacement for Lochinvar boiler maintenance. For field technicians, utilizing this OEM Lochinvar gasket is essential for meeting factory specifications during annual inspections or system overhauls. Whether you are addressing a leaking boiler flange or performing a full burner service, this gasket provides the compression recovery needed for long-term reliability in high-demand hydronic systems.

Key Benefits

• Precise 2-Inch Diameter: Specifically designed for 2" NPT or flanged connections commonly found in Lochinvar and A.O. Smith commercial units.
• Cross-Compatibility: Direct replacement for GKT2707 and GKT2707K, ensuring versatile application across multiple equipment generations.
• High Thermal Resistance: Constructed to withstand the rigorous operating temperatures of high-efficiency condensing boilers without losing elasticity.
• Optimized Compression: Provides a superior seal under varying torque specifications to prevent glycol or water leaks.

Common Questions

Is the 100208768 compatible with older Lochinvar Knight models?
Yes, this 2-inch flange gasket is frequently specified for Knight and Armor series boilers where a 2" flanged interface is required. Always verify your specific model and serial number against the parts list.

Can I use an aftermarket gasket instead of the GKT2707?
While aftermarket options exist, using the OEM Lochinvar gasket (100208768) ensures material compatibility and prevents premature failure caused by chemical interactions with system fluids.

What causes these gaskets to fail prematurely?
Gasket failure is typically caused by over-torquing during installation or extreme domestic hot water temperatures exceeding the component's rated threshold. Proper torque patterns are essential for a lasting seal.
