Armstrong Fluid Technology 805209-000 Flange Gaskets
The Armstrong Fluid Technology 805209-000 Flange Gaskets are precision-engineered OEM replacement parts designed to maintain the peak efficiency of your hydronic pumping systems. Specifically developed for use with Armstrong S35 pumps and the wider Series S circulator line, these gaskets provide a critical, leak-proof seal for 2" and 2-1/2" flange connections. Constructed from durable, high-performance materials including high-density composite fibers, the 805209-000 is an essential component for HVAC pump maintenance and industrial fluid management. These industrial flange gaskets are designed to withstand the rigorous temperature fluctuations and pressure demands typical of commercial heating and cooling applications, preventing system depressurization and fluid loss. By choosing genuine Armstrong pump parts, technicians ensure exact dimensional compatibility and long-term system reliability. Whether performing a routine circulator pump repair or a complete system overhaul, these gaskets offer the positive sealing required to protect sensitive internal components and maintain optimal flow rates across your entire mechanical infrastructure.
Key Benefits- Precision Sealing: Engineered to provide a positive, leak-proof seal specifically for 2" and 2-1/2" flange sizes.
- Perfect Compatibility: Designed specifically for Armstrong S35 pumps and Series S models, ensuring a hassle-free installation.
- Durable Construction: Made from high-quality materials to resist degradation in demanding HVAC pump maintenance environments.
- Efficiency Protection: Prevents fluid leaks and pressure drops, maintaining the operational efficiency of your hydronic heating system.
- Interchangeable Design: Serves as a direct equivalent to B&G part 118065, offering versatility for mixed-fleet maintenance.
What pump models are compatible with the 805209-000 gaskets?
These gaskets are primarily designed for the Armstrong Model S-35 and various Series S circulator pumps. They are also compatible with specific 2-inch flow control valves used in older hydronic systems.
Are these gaskets sold individually or in pairs?
Commonly provided as a set, these gaskets are typically sold in pairs to accommodate both the intake and discharge flanges of a single pump unit.
What is the maximum flange size these gaskets will fit?
These gaskets are dual-rated for 2" and 2-1/2" flange connections, making them a versatile choice for several standard piping configurations.
