Mueller Industries ac14020 Acr Copper Tube 1-1/2 in 20 Ft

Product Description

The MUELLER INDUSTRIES ac14020 is a hard-drawn Type ACR copper tube engineered for refrigeration and air conditioning line set applications. With a 1-5/8 inch OD, 1-1/2 inch nominal size, and a 0.06 inch wall thickness, this tube carries a 347 psi working pressure rating. At 20 feet in length, it provides sufficient run for most residential and light commercial refrigerant line installations. The hard temper construction holds its shape during bending and routing without requiring annealing in typical field conditions. Each piece is incised-marked and color-coded blue for fast, reliable identification on the job site. HVAC technicians and refrigeration mechanics are the primary installers of this product.

This tube is suited for refrigerant suction and liquid line applications in split-system air conditioners, heat pumps, and refrigeration equipment. The ACR designation means the tube is manufactured, cleaned, and capped to minimize internal moisture and contamination, making it ready for refrigerant service. Typical installations include residential split systems and light commercial refrigeration equipment where a 1-1/2 inch nominal suction line is specified. The 20-foot stick length reduces the number of joints required on longer runs.

Key Features

• Hard-drawn temper maintains shape during field routing and support installation
• 1-5/8 inch OD with 0.06 inch wall thickness rated to 347 psi working pressure
• ACR-grade internally clean and capped construction reduces moisture contamination risk
• 20-foot stick length minimizes field joints on standard line set runs
• Blue color-coding and incised markings provide durable, easy identification
• Manufactured to applicable ACR copper tube standards for consistent wall thickness and temper

Compatibility

Designed as an OEM-style and field-replacement ACR copper tube for refrigerant line set applications in residential and light commercial split-system HVAC and refrigeration equipment requiring a 1-1/2 inch nominal hard-drawn suction or liquid line.

Installation Notes

Installation of ACR copper tube in refrigerant systems should be performed by an EPA Section 608 certified HVAC technician. Recover all refrigerant and isolate the system before cutting or brazing any lines. Use nitrogen purge during brazing to prevent internal oxidation scale that can damage compressors and metering devices. Support hard-drawn tube per local mechanical code spacing requirements and avoid sharp bends that could kink the tube wall.
