34-274 Fireye O-Ring

Part number 34-274 from Fireye, listed in Burner & Combustion Controls. KKM Solutions quotes this part with pricing and availability confirmed per order.

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. 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. Specifications Manufacturer: Fireye Part Number: 34-274 Product Type: O-Ring Material: High-performance FKM Viton (90A Durometer) Internal Diameter: Approximately 4.05 inches (or 274 mm depending on standard) Thickness/Cord: 0.2 inches (or 3 mm depending on standard) Weight: 0.01 lb Compatibility: Designed for use with Fireye 60-1199-1 and 60-1199-2 sealing couplings. 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.
