Room Air Conditioner Compressor & Sealed System

This capillary tube is a refrigerant line used in refrigeration systems to meter refrigerant flow; installing the correct length helps restore proper cooling balance and system performance. Fits applications that call for a 34-inch cut-to-length capillary. What it does:

• Meter refrigerant from the liquid line to the evaporator, controlling pressure and flow
• Helps maintain stable evaporator temperatures for consistent cooling
• A damaged, kinked, or clogged capillary can cause poor cooling, frost build-up, or compressor short-cycling
• Installed as part of the sealed refrigerant circuit—works with matched system components

• Handle with care to avoid bending or kinking the tube; capillaries are easily damaged
• Always pressure- and leak-test the system and follow proper evacuating and recharging procedures after replacement
• Verify system compatibility and routing before final installation
