The ROBERTSHAW 11-198 is a 5/8-inch aluminum tubing section used in HVAC and refrigeration systems for refrigerant or gas line connections. Aluminum construction keeps the tubing lightweight while providing adequate corrosion resistance for typical service environments. Licensed HVAC technicians and refrigeration mechanics install this type of tubing during system assembly, repair, or retrofit work. The 5/8-inch outer diameter fits a range of standard fittings and valves found in residential and light commercial equipment.
This tubing is suited for HVAC and refrigeration applications where a lightweight, corrosion-resistant line material is specified. It is commonly used in low-pressure refrigerant circuits, gas pilot lines, and sensing line runs. Installers working on residential split systems, packaged units, or commercial refrigeration equipment may use this tubing when replacing damaged or corroded sections or when fabricating new line sets and control connections.
Designed as an OEM-style aluminum tubing replacement for HVAC, refrigeration, and gas appliance applications requiring 5/8-inch aluminum line material.
Installation should be performed by a licensed HVAC technician or qualified refrigeration mechanic. Before working on any refrigerant or gas line, shut off system power and isolate the refrigerant circuit or gas supply per applicable safety codes. Use proper tube cutters and deburring tools to ensure clean, leak-free connections. Follow all local mechanical codes and manufacturer guidelines when routing and securing tubing.
