ORIFICE TUBE GM BLK & WHT - FJC

The FJC 3012-100 Orifice Tube is a precision-engineered component essential for maintaining optimal performance in General Motors (GM) automotive air conditioning systems. This critical, fixed-restriction device accurately meters refrigerant flow into the evaporator, ensuring the proper balance of pressure and temperature for efficient cooling. Designed for professional technicians, it provides a reliable replacement part for AC system service and repair.

Key Features

• Calibrated Refrigerant Flow: Precisely controls the expansion of high-pressure liquid refrigerant into a low-pressure mist, a crucial step for effective heat absorption in the evaporator.
• GM Specific Design: Engineered to meet the specific requirements of GM vehicle A/C systems, ensuring compatibility and correct functionality.
• Fixed Orifice Reliability: As a fixed device with no moving parts, it offers a consistent and dependable method of refrigerant control within clutch-cycling orifice tube (CCOT) systems.
• Integrated Filtration: Features internal screens to help filter debris from the refrigerant, protecting other sensitive AC components from contamination.
• Durable Construction: Built to withstand the demanding conditions within an automotive AC system, promoting longevity and stable operation.

Applications

The FJC 3012-100 Orifice Tube is specifically used in the air conditioning systems of various General Motors vehicles that utilize an orifice tube rather than an expansion valve. It is a fundamental component for professional mechanics performing AC diagnostics, repairs, and preventative maintenance, particularly when addressing issues such as insufficient cooling or compressor short-cycling, which can often be linked to a clogged or faulty orifice tube. Its installation is critical at the inlet of the evaporator or within the liquid line to divide the high and low-pressure sections of the AC system.
