Mueller Streamline AC02020 Acr Tube 3/8 X 20 Ft

Product Description

The MUELLER STREAMLINE AC02020 is a 3/8-inch ACR copper tube sold as a single 20-foot length. ACR-grade tubing is manufactured to tighter dimensional tolerances than standard plumbing copper and is internally cleaned and capped to keep the bore free of debris and moisture - critical requirements for refrigerant-side connections. HVAC and refrigeration technicians use this tube for lineset fabrication, coil connections, and refrigerant piping runs where clean, dry copper is a code and system-integrity requirement.

This tube is suited for residential and light-commercial HVAC and refrigeration installations. It is appropriate for use in split-system air conditioning, heat pump lineset work, mini-split rough-in, and refrigeration equipment hookups. Sold as a single unit, it fits applications where a full coil is not required and a straight, manageable length is preferred for short runs or field fabrication.

Key Features

• ACR-grade copper tubing cleaned and capped for refrigerant service
• 3/8-inch OD sizing compatible with common refrigerant line applications
• 20-foot straight length for short runs and field-cut installations
• Meets dimensional tolerances required for flare, braze, and swage connections
• Single-unit selling format for targeted purchasing without full-coil overstock

Compatibility

Designed as an ACR-grade copper tube for use in residential and light-commercial refrigerant piping systems where 3/8-inch OD copper tubing is specified.

Installation Notes

ACR tubing installation is typically performed by licensed HVAC or refrigeration technicians in accordance with applicable mechanical codes. Recover and isolate the refrigerant circuit before cutting into any live system. Cut tube ends should be deburred and reamed before brazing, flaring, or swaging to prevent contamination and leaks. Keep end caps in place until the moment of connection to preserve internal cleanliness.
