Resideo 392449-4 Compression Fitting

The Resideo 392449-4 is a professional-grade pilot tubing compression fitting designed for seamless integration with Honeywell pilot burners. Engineered for a precise fit on 1/8" OD pilot tubing, this fitting features an overall length of 1.15 inches, making it the correct specification for tight clearances in both standing pilot and intermittent pilot applications. As a veteran-preferred component, the 392449-4 is chemically and dimensionally identical to the 392449-4/U, ensuring a leak-free seal on gas valve pilot lines.

This HVAC compression fitting is built for high-demand environments, maintaining structural integrity across various gas control valve models, including the VR8200, VR8300, and SV9501 series. Whether you are performing a routine furnace service or a complex boiler repair, utilizing the genuine Resideo 392449-4 ensures compatibility with brass pilot gas lines and prevents the common mechanical failures associated with generic sub-components. For contractors, having a reliable 1/8 inch pilot nut and sleeve assembly is critical for maintaining system safety and optimizing burner ignition cycles.

• Universal Compatibility: Specifically designed for 1/8" OD tubing used in Honeywell Home and Resideo pilot burner assemblies.
• Direct Replacement: Fully interchangeable with 392449-4/U, providing a standardized solution for intermittent pilot and standing pilot systems.
• Precision Dimensions: The 1.15" length provides ample thread engagement for a leak-proof connection without bottoming out in the valve port.
• Broad Application: Compatible with a wide range of combination gas controls, including V800, VR8100, and VR8204 models.

Is the 392449-4 compatible with 1/4" pilot lines?
No, this fitting is precision-machined for 1/8 inch outside diameter (OD) tubing. For 1/4" applications, a different sleeve and nut size is required.

Can this be used on both Natural Gas and Liquid Propane systems?
Yes, the Resideo 392449-4 is a mechanical compression fitting suitable for the pilot lines on both NG and LP gas valves, provided the tubing material is compatible with the gas type.

What is the difference between 392449-4 and 392449-4/U?
There is no functional or technical difference; the "/U" suffix simply denotes "Universal" packaging for retail or wholesale distribution. They are the same Resideo technical part.
