Modine 5H0750260049 Orifice

As a veteran HVAC technician, I know that maintaining precise combustion in Modine gas-fired unit heaters starts with the correct natural gas orifice. The Modine 5H0750260049 is a genuine OEM replacement part designed to regulate gas pressure and volume with tight tolerances. This brass component is critical for inducing the specific pressure drop required for efficient manifold delivery, ensuring your burner assembly operates at peak performance without wasting fuel or causing flame instability.

This Modine burner orifice is engineered specifically for the Hot Dawg series and other popular unit heaters. When you are out in the field dealing with a restricted or improperly sized orifice, swapping it for this genuine Modine part is the only way to ensure the equipment stays within its factory-specified BTU input ratings. It is a direct fit for the HD30, HD45, HD60, and HD75AH01 models, making it a staple for any service truck specializing in light commercial or residential garage heating systems.

Key Benefits:

• Precision Flow Control: Ensures the exact fuel-to-air ratio for clean combustion and optimal heat transfer.
• OEM Compatibility: Guaranteed fit for HD30AH01, HD45AH01, HD60AH01, and HD75AH01 Modine heaters.
• Rugged Construction: Machined from high-grade brass to withstand high-temperature environments within the burner manifold.
