Mueller Industries LH30010 Copper Round Tube 3.125 in Od

Product Description

The MUELLER INDUSTRIES LH30010 is a copper round tube measuring 3.125 inches outside diameter with a 3 inch inside diameter and a wall thickness of 0.09 inches. The tube ships in a 10-foot length and weighs 33.3 pounds. Copper tubing of this diameter is a standard material in commercial HVAC, refrigeration, and plumbing systems where large-bore fluid or refrigerant transfer is required. Licensed plumbers, HVAC technicians, and pipefitters work with this size tube when fabricating or replacing distribution mains, risers, or large-diameter supply and return lines.

This tube is suited for commercial and industrial installations that require a large outside diameter copper section. Typical applications include chilled water and hot water piping systems, large commercial refrigeration line sets, and industrial plumbing distribution. The 10-foot straight length supports field cutting to required dimensions. At 33.3 pounds per length, proper material handling and staging are important on the job site.

Key Features

• 3.125 inch outside diameter with a 3 inch inside diameter for high-flow capacity
• 0.09 inch wall thickness suitable for standard commercial pressure service
• 10-foot straight length allows flexible field fabrication and cutting
• Copper construction provides corrosion resistance and thermal conductivity
• Consistent OD tolerances support reliable soldering, brazing, or press-fit joining

Compatibility

Designed as a standard OEM-style copper round tube for use in commercial HVAC, refrigeration, and plumbing piping systems requiring a 3.125 inch outside diameter straight tube section.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or pipefitter in accordance with applicable local codes, IFGC, and IPC requirements. Shut off the system and relieve all pressure before cutting into any existing piping. Use proper tube cutters, deburring tools, and flux rated for the joining method, whether soldering or brazing. Support the tube at appropriate intervals per code to prevent sag and vibration stress on joints.
