Resideo 388146KP Orifice

For service technicians handling SmartValve system repairs or propane conversions, the Resideo 388146KP Orifice provides the exact metering required for stable pilot operation. This 0.014-inch diameter orifice is specifically engineered for LP gas (Liquid Propane) applications, ensuring the correct fuel-to-air ratio for efficient ignition. Stamped with the KR14 identifier, this ribbed-style component is a direct replacement part designed to maintain the performance of Resideo and Honeywell pilot burners. The assembly includes a 1/4-inch compression fitting with a 1.20-inch length, facilitating a gas-tight seal and straightforward integration into existing pilot lines. Maintaining a precise propellant flow rate is critical in preventing pilot outages or delayed ignition in residential heating systems. Precision-machined for durability, this orifice is a staple for contractors stocking HVAC service parts for intermittent pilot assemblies and standing pilot gas valves.

• Optimized LP Gas Flow: The 0.014" orifice diameter is precision-calibrated to deliver the exact BTU input required for propane pilot assemblies.
• Universal Compatibility: Seamlessly integrates with SmartValve pilot burners and series including Q348, Q3480, Q3481, Q327, and Q179.
• Technician-Ready Fit: Includes a factory-spec 1/4" compression fitting to eliminate the need for additional adapters during a service call.
• Quick Identification: Features the KR14 stamp on the faceted body, allowing for rapid verification of orifice size in the field.

• Which gas type is the Resideo 388146KP compatible with? This specific orifice is exclusively designed for LP gas (propane) systems; do not utilize this part for natural gas applications.
• Does this include the compression nut and sleeve? This assembly includes the 1/4" compression fitting, providing a complete pilot line connection solution.
• Can I use this for a Honeywell SmartValve system? Yes, this replacement orifice is the standard component for many Resideo SmartValve pilot burners used in modern furnaces and boilers.
