Nordyne 664080R Orifice

The Nordyne 664080R Orifice is a precision-engineered .080 Restrictor Orifice designed for specific gas flow regulation within Nordyne HVAC systems. As a critical OEM replacement part, this #80 distributor orifice is foundational for maintaining the correct manifold pressure and ensuring clean combustion in residential furnaces and packaged units. This part is functionally identical to the Nordyne 664080, providing a direct-fit solution for technicians performing manifold adjustments or conversions. Utilizing genuine Nordyne parts prevents common issues like improper gas-to-air ratios, which can lead to soot buildup or heat exchanger stress. When troubleshooting burner performance or verifying input rates, installing a correctly sized restrictor orifice is essential for equipment longevity and meeting factory performance curves. This brass component is manufactured to tight tolerances to handle the thermal demands of high-efficiency heating cycles without orifice deformation.

• Exact Flow Calibration: The #80 (.080") sizing ensures precise British Thermal Unit (BTU) input per burner according to manufacturer nameplate ratings.
• Direct OEM Interchange: Fully compatible with legacy 664080 specifications, ensuring 100% mechanical fit in the burner manifold.
• Optimized Combustion: Helps maintain the proper flame characteristics and prevents over-firing or under-firing of the furnace sections.
• Durable Brass Construction: Resists corrosion and thermal expansion, maintaining aperture integrity over thousands of heating cycles.

Is the 664080R compatible with LP conversion kits?
Size .080 is typically used for specific Natural Gas configurations depending on the BTU rating of the burner; always consult the Nordyne orifice sizing chart for your specific altitude and gas type before installation.

Can I use this orifice in Miller or Intertherm units?
Yes, since Nordyne manufactures Miller and Intertherm, the 664080R orifice is the standard OEM HVAC part for those brands, provided the model specifications call for a .080 restrictor.

How do I verify if I need a #80 sized orifice?
Check the equipment data plate or the burner orifice manifold. Using an incorrectly sized orifice can cause unsafe CO levels or equipment failure.
