Mueller Industries LSC4020P Copper Seamless Tube 5/8 in Od

Product Description

The MUELLER INDUSTRIES LSC4020P is a 20-foot length of seamless copper tubing rated for refrigeration, HVAC, and plumbing applications. The tube measures 5/8 inch outside diameter with a 0.545 inch inside diameter and a 0.040 inch wall thickness, yielding a nominal 1/2 inch pipe size. Seamless construction eliminates longitudinal weld seams, which improves pressure integrity and reduces the risk of failure at high-cycle or high-pressure service points. Each length weighs approximately 5.7 pounds and delivers 0.285 pounds per foot. Licensed HVAC technicians and plumbers select this tubing for lines that require consistent wall thickness and clean bends without crimping.

This tubing is suited for residential and light commercial HVAC systems, refrigerant suction and liquid lines, hydronic distribution, and general copper plumbing rough-in. The 5/8 inch OD dimension is a standard refrigerant line size used in split-system air conditioning and heat pump installations. The 20-foot straight length is useful for longer runs where coiled tubing would require straightening before installation.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber in accordance with applicable mechanical and plumbing codes, including IFGC and IPC guidelines where relevant. Isolate and recover any refrigerant before cutting into an existing refrigerant circuit. Use a tubing cutter rather than a saw to maintain clean, deburr-ready ends. Deburr all cut ends before flaring, swaging, or soldering to prevent contamination of the system.
