Reznor 9664 Fitting

The Reznor 9664 is a precision-engineered 1/4" break-away compression fitting designed for critical gas pilot lines and regulator connections. This OEM Reznor replacement part features a high-grade brass construction that provides superior corrosion resistance in high-heat environments typically found in industrial unit heaters. The break-away design is a vital safety and maintenance feature, engineered to fail at a specific torque profile to protect more expensive gas valve components and pilot assemblies from mechanical stress or overtightening. Each fitting includes the necessary nut and ferrule to ensure a leak-proof seal on standard 1/4-inch OD tubing. For field technicians, using genuine Reznor HVAC fittings is essential for maintaining the UL certification and pressure integrity of power-vented and separated-combustion units. This 1/4" brass compression fitting facilitates rapid service of pilot gas lines and ensures precise fuel delivery to the burner assembly, preventing nuisance outages and maintaining system efficiency.

• System Protection: The break-away functionality prevents over-torque damage to sensitive gas regulators and pilot burner ports.
• Durable Material: Heavy-duty brass construction resists oxidation and thermal fatigue in demanding HVAC cabinet conditions.
• Leak-Free Seal: Precision-machined nut and ferrule kit provides a secure mechanical grip on 1/4" pilot tubing.
• Compatibility: Direct OEM replacement for various Reznor unit heaters, ensuring exact fitment without field modifications.
