Carrier LH32RF129 Orifice

The Carrier LH32RF129 is a precision-engineered natural gas orifice designed for specific gas-fired heating applications, including the 48KCFA and 48TCFA series rooftop units. As a critical OEM burner orifice, this component features a #30 spud size, accurately calibrated to regulate the manifold pressure and gas flow rate. Proper fuel-to-air ratios are essential for maintaining stable flame patterns and preventing hazardous conditions such as delayed ignition or soot accumulation. This Carrier gas furnace part is constructed from high-grade, corrosion-resistant brass to withstand the thermal stress and high-pressure environment of the burner assembly. Using a genuine Carrier burner orifice ensures that your equipment operates at peak fuel efficiency while meeting original factory thermal output specifications. For contractors performing natural gas to propane conversions or routine manifold maintenance, this orifice provides the exact tolerances required for safe, reliable combustion. Verify your specific model and serial number to ensure compatibility with this #30 spud orifice.

• Precision Gas Regulation: The #30 spud opening ensures accurate BTUs per hour by precisely metering fuel flow to the burner.
• Enhanced Combustion Safety: Proper orifice sizing prevents over-firing and reduces the risk of backfires or carbon monoxide buildup.
• Durable Brass Construction: Resists high-temperature oxidation and chemical corrosion common in gas-fired heat exchangers.
• OEM Compatibility: Specifically engineered for Carrier, Bryant, and Payne HVAC systems to maintain laboratory-tested performance levels.

• What is the drill size for the LH32RF129 orifice? This part is a standard #30 spud orifice, which is the specific diameter required for the manifold pressure settings on compatible natural gas models.
• Can this orifice be used for LP conversion? This specific model is designed for natural gas systems. For liquid propane (LP) conversions, a different orifice size and spring kit are typically required.
• Which Carrier models use the LH32RF129? It is commonly found in Carrier 48KCFA and 48TCFA series units, though you should always check the parts list for your specific serial number.
