transforming them into reliable condensate timer drains that prevent corrosive buildup and freeze damage

Carrier 311166-755 Tubing Assembly 322055-301 Field technicians often spec thisThe Carrier 311166 755 Tubing Assembly is an OEM discharge line engineered for precise refrigerant flow management within specific Carrier, Bryant, and Payne condensing units. This HVAC replacement part is fabricated from high grade copper to withstand the thermal expansion and high pressure cycles common in R 410A systems. The assembly includes integrated vibration clamps, which are critical for mitigating harmonic resonance and preventing fatigue
