Mueller Industries LS20040 Seamless Copper Tube 2-1/8 in Od

Product Description

The MUELLER INDUSTRIES LS20040 is a seamless copper tube designed for fluid and refrigerant piping applications in HVAC, plumbing, and mechanical systems. Measuring 2-1/8 inches outside diameter with a 1.86-inch inside diameter and a 0.07-inch wall thickness, this tube ships in a 40-foot length and weighs approximately 1.75 pounds per foot. The seamless construction eliminates weld seams, reducing the risk of weak points along the run. Licensed plumbers, HVAC technicians, and pipefitters are the primary installers for this size and type of copper tube.

This tube is suited for commercial and residential installations where a 2-1/8-inch OD seamless copper line is specified. Common applications include refrigerant suction lines, chilled water piping, condenser water systems, and large-diameter domestic plumbing runs. The 40-foot length allows for longer uninterrupted runs, reducing the number of field joints required on a given installation. Nominal size for this tube is 2 inches, consistent with standard copper tube sizing conventions.

Key Features

• Seamless construction — no weld seam along the tube wall
• 2-1/8 inches outside diameter with a 0.07-inch wall thickness
• 40-foot length at 1.75 pounds per foot — approximately 70 pounds per stick
• Copper material provides excellent thermal conductivity and corrosion resistance in wet and refrigerant service
• Nominal 2-inch sizing aligns with standard copper tube fittings and hangers

Compatibility

Designed as an OEM-style seamless copper tube replacement or new-installation material for systems requiring a 2-1/8-inch OD copper line with nominal 2-inch sizing.

Installation Notes

Installation should be performed by a licensed plumber or certified HVAC technician in accordance with applicable local codes, IPC, or IFGC requirements. Shut off and isolate the system — including refrigerant recovery or water shutoff as applicable — before cutting or joining the tube. Use appropriate copper tube cutters, reamers, and either brazed or press-fit fittings rated for the service conditions. Support spacing should follow manufacturer and code guidelines for 2-inch nominal copper tube to prevent sagging over the 40-foot run.
