ORIFICE TUBE GM BL - FJC

The FJC 3006 Orifice Tube is a vital component for restoring and maintaining optimal performance in General Motors (GM) automotive air conditioning systems. This blue orifice tube is engineered to precisely meter the flow of refrigerant between the condenser and evaporator, a critical function that ensures efficient pressure drop and effective cooling within the A/C system. It also acts as a filter, protecting the system from damaging debris.

Key Features

• GM Specific Design: Manufactured to exact OEM specifications for a direct fit and reliable performance in a wide range of GM vehicles. The blue color often indicates a specific orifice diameter, typically 0.067 inches, crucial for precise refrigerant metering.
• Optimized Refrigerant Flow: Controls the volume and pressure of liquid refrigerant entering the evaporator, facilitating the necessary phase change for heat absorption and cold air production.
• System Protection: Features a fine mesh screen to filter out contaminants and debris, preventing clogs that can lead to A/C inefficiency or severe compressor damage.
• Durable Construction: Built with professional-grade materials to withstand the demanding conditions of automotive A/C systems, ensuring long-lasting operation.
• Restores A/C Efficiency: A direct replacement for a common failure point, helping to resolve issues like poor cooling, inconsistent vent temperatures, and reduced overall A/C performance.

Applications

This FJC 3006 orifice tube is an essential replacement part for professional technicians and mechanics addressing A/C system malfunctions in GM vehicles. It is commonly used when diagnosing issues such as inadequate cooling, a lack of cold air, or when debris is suspected within the refrigerant lines. The orifice tube is typically located in the liquid line, often near the firewall or at the inlet of the evaporator, and sometimes in the condenser outlet pipe, depending on the specific GM model. Replacing a clogged or failed orifice tube is a fundamental step in comprehensive A/C system repairs, ensuring proper refrigerant cycling and protecting other expensive components like the A/C compressor.
