3/8" x 5/8" x 1/2" 25' Copper Line Set Black Plain End Mini-Split Duraguard Insulated Both Lines.

Streamline® 61020250B6C – Mini-Split Copper Line Set for High-Pressure HVAC Applications

The Streamline® 61020250B6C copper line set is designed to support high-efficiency HVAC installations, including mini-split and variable refrigerant flow (VRF) systems. This set includes both 3/8" and 5/8" outside diameter (OD) lines, pre-insulated with 1/2" closed-cell polyethylene foam and protected with a UV-resistant jacket, suitable for interior and exterior routing.

Each set is factory-sealed, nitrogen-charged, and capped to maintain internal cleanliness during transport and prior to system assembly. Manufactured from Type L UNS C12200 copper tubing, the line set meets the mechanical and thermal requirements of modern refrigerant systems using R-410A, R-32, or legacy refrigerants.

Product Overview

• Material: Seamless Type L copper, UNS C12200
• Line Dimensions: 3/8" OD (liquid) x 5/8" OD (suction)
• Insulation: 1/2" wall, closed-cell polyethylene with UV-resistant jacket
• Length: 25 feet
• Operating Pressure: Rated up to 700 PSI
• Temperature Range: -40°F to 248°F (-40°C to 120°C)
• Packaging: Coiled in parallel, boxed, sealed, and capped

Performance Features

• Nitrogen-Charged and Sealed – Prevents internal oxidation and maintains line integrity pre-installation
• Uniform Insulation Thickness – Reduces energy loss and condensation on suction line
• UV-Stable Outer Jacket – Suitable for exposure to light and weather in exterior installations
• Parallel Coil Design – Facilitates cleaner pulls through framing or duct chases
• Field-Ready Termination – Ends are capped and prepared for brazed or flared connections per system requirements

Installation Considerations

This line set is manufactured for use in professional HVAC systems where pressure testing, brazing, or flaring are performed by licensed technicians. Proper torque values should be used on all flare connections, and insulation should be inspected before and after routing to ensure no damage has occurred during pull-through.

Application Use Cases

• Ductless mini-split systems
• Multi-zone split configurations
• VRF/VRV systems
• Residential and light-commercial installations

The Streamline® 61020250B6C is designed for HVAC professionals seeking precision-fabricated, pressure-rated line sets that meet high-performance installation demands. Its durable materials, consistent quality control, and compatibility with industry-standard refrigerants make it a preferred choice for efficient and secure system connections.
