Mueller Industries D 05050P Copper Seamless Tube 5/16 Od

Product Description

The MUELLER INDUSTRIES D 05050P is a seamless copper tube supplied in a 50-foot coil, engineered for refrigeration and HVAC line-set work. Manufactured from C12200 phosphorus-deoxidized copper and conforming to ASTM B280, it carries an outside diameter of 5/16 inches, an inside diameter of 0.2485 inches, and a wall thickness of 0.032 inches. The seamless construction eliminates weld seams, supporting reliable pressure containment in refrigerant circuits. Licensed HVAC technicians and refrigeration mechanics are the primary installers for this product type.

This tube is suited for residential and light commercial refrigeration and air conditioning applications where small-diameter copper line is required. Typical uses include capillary-adjacent distribution lines, refrigerant suction and liquid lines in compact systems, and OEM equipment fabrication. The 50-foot coil length provides enough material for most single-system installations or repair runs without a field splice. The C12200 alloy is the standard ACR copper grade recognized across the HVAC and refrigeration trades.

Key Features

• Seamless construction per ASTM B280 and UNS C12200 for refrigeration-grade service
• 5/16 inch OD with 0.032 inch wall thickness for consistent flow area and pressure integrity
• C12200 phosphorus-deoxidized copper alloy resists internal oxidation during brazing
• 50-foot coil format minimizes field joints on single-system runs
• Coil weight of approximately 5.50 pounds for manageable job-site handling

Compatibility

Designed as an OEM-style ACR copper tube for residential and light commercial refrigeration and HVAC systems requiring 5/16 inch OD seamless copper line conforming to ASTM B280.

Installation Notes

Installation should be performed by a licensed HVAC or refrigeration mechanic in accordance with applicable mechanical codes and EPA Section 608 refrigerant handling requirements. Recover and isolate the refrigerant circuit before cutting or disconnecting existing lines. Use a sharp tube cutter rather than a hacksaw to preserve end-face geometry and prevent copper chips from entering the system. All brazed joints on ACR copper must be performed with nitrogen purge to prevent internal oxidation scale.
