DENSO 4754107 A/C Orifice Tube 10-Pack

The DENSO 4754107 A/C Orifice Tube is a critical component in automotive air conditioning systems, serving as the dividing point between the high-pressure and low-pressure sections of the A/C system. This precision-engineered orifice tube regulates the flow of refrigerant into the evaporator, controlling temperature and pressure to ensure optimal cooling performance.

Key Features:

• 10-pack quantity for shop or fleet use
• Precision-built brass metering element for accurate refrigerant flow control
• Dual mesh screens on both ends filter debris and protect against contamination
• Direct replacement design for Ford, Lincoln, and Mercury applications
• Made in USA with 2-year manufacturer warranty
• Simple design with no moving parts for reliable, long-lasting performance
• Length: 87mm (3.43 inches)

As refrigerant passes through the narrow orifice, it rapidly expands and drops in pressure, transforming from high-pressure liquid to a cold, low-pressure mist before entering the evaporator. This pressure drop is essential for proper heat absorption and efficient cabin cooling. The integrated filter screens trap metal shavings, dirt, and other contaminants that could damage downstream A/C components.

DENSO is the world's largest OE supplier of A/C components, providing the same quality parts used by major vehicle manufacturers. Each orifice tube is manufactured to strict OEM specifications, ensuring proper fit and function. The orifice tube should be replaced whenever major A/C system components are serviced, or when contamination or clogging is detected during system diagnosis.
