Carrier 323267-701 Manifold Orifice

The Carrier 323267-701 Manifold Orifice is a precision-engineered #42 drill size component designed explicitly for natural gas furnace applications. As a veteran-grade OEM replacement part, it ensures the exact gas flow rate and manifold pressure required for optimal combustion in residential and commercial heating equipment. This specific furnace orifice serves as the direct LH32DB207 replacement, maintaining the factory-specified BTU output and preventing safety issues like incomplete combustion or soot buildup. Manufactured from a durable metal alloy to withstand high thermal cycling, it provides the reliability professional contractors expect during a gas burner orifice swap. The 323267-701 is compatible with a broad range of Carrier, Bryant, and Payne HVAC units, including the 58CTW, 58CVA, 59MN7A, and PG8DAA series. Proper installation is critical for HVAC system efficiency; technicians should verify the manifold pressure against the unit’s rating plate after installing this manifold orifice to ensure peak performance and safe operation under standard line pressures.

• Direct OEM Compatibility: Serves as the official 323267-701 replacement for LH32DB207, ensuring exact physical fit and flow characteristics.
• Optimized Combustion: The #42 orifice size is calibrated for natural gas, providing precise regulation of fuel delivery to the burner assembly.
• Robust Construction: Built from high-quality metal alloy to resist corrosion and structural fatigue in high-heat environments.
• Wide Application Range: Verified for use across multiple Bryant and Carrier furnace parts catalogs for consistent stock versatility.

Is the 323267-701 compatible with Liquid Propane (LP) systems?
No, this orifice is specifically sized for natural gas applications. Using this #42 orifice with propane will result in improper combustion and dangerous operating conditions; always use the manufacturer-specified LP conversion kit for propane applications.

When should a manifold orifice be replaced?
Orifices should be replaced if they show signs of physical damage, cross-threading, or if the internal bore has been improperly cleaned with a wire that may have enlarged the opening, affecting the gas flow rate.

What is the drill size for this Carrier orifice?
This part is a #42 drill size, which is the standard specification for many natural gas manifold configurations in Carrier family heating products.
