The 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-related fractures at the brazed joints. As a direct-fit compressor discharge tube, it ensures proper alignment and clearance within the cabinet, maintaining factory-spec airflow and component spacing. For technicians performing a compressor swap or leak repair, utilizing this specific OEM copper tubing kit ensures the internal volume and pressure drop parameters remain within the original design tolerances, preventing premature wear on the compressor valves and maintaining system efficiency across high-ambient cooling demands.

Item is Non Cancelable / Non Returnable

Key Benefits

• Reduced Vibration: Factory-installed clamps minimize mechanical stress on the refrigerant circuit.
• Direct Fitment: Pre-bent OEM specifications eliminate the need for field fabrication and torch-time in tight cabinets.
• Material Integrity: Constructed from refrigeration-grade copper to ensure chemical compatibility with POE oils.
• Optimized Flow: Designed to maintain the specific head pressure requirements of the outdoor coil.

Common Questions

Is this tubing assembly compatible with all Carrier puron units?
No, this assembly is specific to certain model tonnages and cabinet sizes. Always verify the product data sheet or model number prefix before installation.

Does the kit include the mounting hardware for the clamps?
The Carrier 311166-755 typically includes the integrated clamps; however, reuse of existing cabinet bolts or standard self-tapping screws is usually required for securing to the chassis.

Can this tube be used on a suction line repair?
No, this is specifically a discharge line assembly designed for high-side pressure and temperature specifications. It cannot be substituted for suction-side applications.
