The Reznor 97572 is a precision-engineered 1/8" compression fitting designed specifically for integration with Reznor unit heater gas valves and pilot assembly lines. Built to withstand the high-cycle demands of industrial and commercial heating applications, this fitting ensures a gas-tight seal between the pilot tubing and the gas control valve. It is a critical component for maintaining consistent pilot flame signal and preventing nuisance shutdowns due to pressure drops or leaks at the manifold. This OEM Reznor replacement part features durable brass construction, providing the necessary corrosion resistance for long-term service in various mechanical room environments. Whether you are performing a seasonal tune-up or a full pilot assembly overhaul, utilizing authentic Reznor fittings ensures the equipment maintains its original UL/CSA certification performance standards. The 1/8-inch NPT sizing allows for seamless compatibility across a wide range of Reznor F, FE, and B series heaters, making it a staple for any service technician's truck stock. Key Benefits for Technicians Precision Machined Brass: Provides a reliable metal-to-metal seal that resists stripping and vibration-induced loosening. Direct OEM Fitment: Eliminates the guesswork associated with universal fittings, ensuring correct gas valve manifold alignment. High Pressure Resilience: Rated to handle the standard WC pressure requirements of natural gas and propane heating systems without leakage. Ease of Installation: Designed for standard wrench sizes, allowing for quick field replacement during HVAC pilot assembly repairs. Common Service Questions What causes a compression fitting to leak on a Reznor heater? Leaks typically occur due to over-tightening, which deforms the ferrule, or from reused fittings that have already been set to a specific tube depth. Always inspect the pilot tubing for scoring before installation. Is the Reznor 97572 compatible with all 1/8" pilot lines? While it fits standard 1/8" OD tubing, it is specifically optimized for Reznor unit heater specifications to ensure the taper matches the gas valve inlet precisely. Does this fitting require thread sealant? No, the compression end relies on mechanical deformation of the sleeve to create a seal. Applying pipe dope to the compression threads can actually interfere with proper seating. Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
