Raypak 800080B Flange Gasket

The Raypak 800080B Flange Gasket is a critical high-temperature seal designed for commercial and residential pool heater heat exchangers. This 2-pack of replacement gaskets ensures a gas-tight, leak-proof connection between the header flange and the heat exchanger tube sheet, maintaining operational pressure and thermal efficiency. Engineered for durability, these gaskets are compatible with a wide range of Raypak atmospheric heaters and Hi Delta units, including models 181, 261, 331, and 401. As a veteran technician knows, preventative heater maintenance requires using OEM-spec components to avoid BTU output loss or dangerous exhaust leaks. These gaskets feature a high-density composition that resists degradation from chemical exposure and thermal cycling. Replacing the heat exchanger gasket during routine teardowns prevents costly site visits and preserves the hydraulic integrity of the HVAC hydronic system. Ensure surfaces are clean of old residual material before installation to guarantee proper Raypak heater repair outcomes.

• OEM Compatibility: Precision-cut for a perfect fit on Raypak header flanges, eliminating the need for sealant modifications.
• High-Temperature Resistance: Formulated to withstand the rigorous thermal demands of gas-fired heat exchangers without hardening.
• Value 2-Pack: Provides both the inlet and outlet gaskets required for a complete header service.
• Leak Prevention: Maintains a secure seal to prevent water damage to the combustion chamber and burner tray.

When should the Raypak 800080B gaskets be replaced?
These should be replaced any time the header is removed for heat exchanger cleaning, descaling, or if visible signs of weeping or calcification appear around the flange bolts.

Are these gaskets compatible with both bronze and cast iron headers?
Yes, the 800080B is designed to seal effectively against various header materials used in Raypak's copper finned tube heater lines.

Do I need to apply RTV silicone with these gaskets?
No, these gaskets are designed for dry installation. Using RTV can sometimes interfere with the compression seal and make future removal more difficult.
