Buy Mercury Villager A/C Orifice Tubes

The air conditioning orifice tube is a crucial component in your vehicle's A/C system. This small, fixed device helps regulate the flow of refrigerant, ensuring that your car's air conditioning operates efficiently to keep you cool during warm weather.

The A/C orifice tube, also known as an expansion tube or metering device, controls the amount of refrigerant entering the evaporator. It reduces the high-pressure liquid refrigerant into a low-pressure mist, allowing it to absorb heat from the cabin air effectively. This process is essential for the proper cooling function of the air conditioning system.

A malfunctioning orifice tube can lead to several noticeable issues:

Insufficient Cooling: If the orifice tube is clogged or damaged, the A/C system may not cool the air adequately.
Frost Accumulation: Blockages can cause frost or ice to form on the orifice tube or other parts of the system.
Unusual Noises: Whistling or hissing sounds may indicate a problem with refrigerant flow through the orifice tube.
Compressor Problems: Incorrect refrigerant flow can strain the compressor, potentially leading to failure.

Proper care and installation of the A/C orifice tube can extend the life of your air conditioning system:

Regular Inspection: Periodically check the orifice tube for signs of wear or blockage, especially if experiencing cooling issues.
System Flushing: When replacing the orifice tube, it's advisable to flush the entire A/C system to remove contaminants that could clog the new tube.
Use Correct Replacement: Ensure that the replacement orifice tube matches your vehicle's specifications, as different models may require specific types.
Professional Assistance: Consider having a qualified technician perform the replacement to ensure it's installed correctly and safely.

Drivers often report issues related to clogged orifice tubes caused by debris or sludge in the A/C system. Such blockages can hinder refrigerant flow, leading to reduced cooling efficiency. Regular maintenance helps prevent these problems by keeping the refrigerant clean and the system free of contaminants.

Selecting the right orifice tube is essential for optimal A/C performance. Orifice tubes are often color-coded to indicate different flow rates and specifications. Using the correct type ensures that the refrigerant moves through the system at the proper rate, providing efficient cooling and preventing potential damage to other components.
