Mueller Industries D 14050P Copper Seamless Tube 7/8 in Od

Product Description

The MUELLER INDUSTRIES D 14050P is a seamless copper refrigeration tube supplied as a 50-foot coil. It measures 7/8 inch outside diameter with a 0.785 inch inside diameter and a 0.045 inch wall thickness. Manufactured from C12200 phosphorus-deoxidized copper and meeting ASTM B280 and UNS C12200 standards, this tube is suited for refrigerant line sets, ACR applications, and related HVAC-R work. The seamless construction eliminates weld seams, reducing the risk of porosity or leak paths at the tube wall. Licensed HVAC technicians and refrigeration mechanics are the primary installers.

This tube is used in residential and light commercial refrigeration and air conditioning systems where ACR-grade copper is required. Common applications include suction and liquid line fabrication, evaporator and condenser connections, and other refrigerant-carrying runs. The 50-foot coil length provides enough material for most residential line set runs or multiple shorter commercial connections without a field splice. It is handled and installed in compliance with applicable mechanical codes and refrigerant handling regulations.

Key Features

• Seamless construction per ASTM B280 eliminates weld-seam leak paths
• C12200 phosphorus-deoxidized copper material grade for ACR service
• 7/8 inch OD with 0.045 inch wall thickness for standard ACR line sizing
• 50-foot coil minimizes field splices on longer residential runs
• Meets UNS C12200 material standard

Compatibility

Designed as an OEM-style and field replacement ACR copper tube for residential and light commercial refrigeration and air conditioning line set applications requiring 7/8 inch OD seamless copper per ASTM B280.

Installation Notes

Installation should be performed by a licensed HVAC-R technician or refrigeration mechanic. Evacuate and recover all refrigerant from the system before cutting or connecting any refrigerant lines. Use a tubing cutter sized for copper ACR tube and ream all cut ends to remove burrs before brazing or flaring. Brazing of ACR copper lines typically requires nitrogen purging during the braze process to prevent internal oxidation scale.
