Mueller Industries D 12050P Copper Seamless Tube 3/4 in Od

Product Description

The MUELLER INDUSTRIES D 12050P is a seamless copper tube coil designed for ACR (air conditioning and refrigeration) applications. Manufactured from C12200 phosphorus-deoxidized copper and conforming to ASTM B280 and UNS C12200 standards, this coil delivers the cleanliness and pressure integrity that refrigerant systems demand. The tube measures 3/4 inch OD with a 0.555 inch ID and a 0.035 inch wall thickness, offered in a 50-foot coil weighing approximately 15.20 pounds. HVAC and refrigeration technicians rely on this tube for field fabrication of refrigerant lines, evaporator and condenser connections, and custom copper piping runs.

This coil is suited for residential and light commercial HVAC and refrigeration installations where ACR-grade seamless copper tubing is required. The 50-foot length provides enough material for most field-routed refrigerant line sets and custom fabrication work. Installers working on split systems, package units, walk-in cooler piping, and similar refrigeration circuits will find this coil appropriate for suction and liquid line applications. The ASTM B280 designation confirms the tube meets the internal cleanliness and dimensional tolerances required for refrigerant service.

Key Features

• Seamless construction meets ASTM B280 and UNS C12200 standards for ACR service
• C12200 phosphorus-deoxidized copper for reliable brazing and corrosion resistance
• 3/4 inch OD with 0.035 inch wall thickness for consistent dimensional tolerance
• 50-foot coil length suits extended refrigerant line runs and field fabrication
• Coil weight of approximately 15.20 pounds for manageable jobsite handling

Compatibility

Designed as an ACR-grade seamless copper tube suitable for use in air conditioning, refrigeration, and heat pump refrigerant piping systems where ASTM B280 copper tubing is specified.

Installation Notes

Installation of ACR copper tubing is typically performed by licensed HVAC or refrigeration technicians. Purge the tube with dry nitrogen during brazing to prevent internal oxidation that can contaminate the refrigerant circuit. Follow applicable mechanical and refrigeration codes, including ASHRAE 15 and local amendments, when sizing and routing refrigerant lines. Ensure all refrigerant system work involving pressurized lines is performed with the system recovered and depressurized before cutting or connecting tubing.
