34-274 Fireye O-Ring

Overview

The Fireye 34-274 is a precision-engineered O-ring designed as a critical sealing component for industrial flame safeguard and burner management systems. This genuine replacement part is specifically manufactured to ensure a gas-tight and liquid-tight seal in high-performance combustion environments, preventing pressure loss and hazardous leaks. It is primarily utilized within sealing couplings to maintain the integrity of the sensing path for flame scanners.

Features

• High-grade elastomer construction, typically FKM (Viton), providing excellent thermal stability and durability.
• Precision-molded design ensures an exact fit for specific Fireye coupling assemblies to prevent bypass leaks.
• Resists “compression set” and “extrusion,” maintaining its profile and sealing force under fluctuating system pressures.
• Engineered to withstand harsh industrial environments, including exposure to heat and chemical degradation.
• Simple, toroidal seal design allows for efficient sealing in both static and dynamic applications.

Applications

The Fireye 34-274 O-ring is used in commercial and industrial HVACR burner assemblies to provide a secure seal for flame scanner mounting. It is a vital component for Fireye 45UV3-1050 scanners and BurnerLogix configurations where it interfaces with the 60-1199 series sealing couplings. This O-ring is essential for maintaining the safety and reliability of combustion systems by resisting degradation from fuel oils, natural gas, and propane while operating under continuous thermal stress.
