The KLEIN TOOLS v-hlr-050-0500 is a coiled copper refrigeration tubing product measuring 0.5 inches in outer diameter and 50 feet in length. Copper refrigeration tubing is a core material in HVAC and refrigeration work, used to carry refrigerant between system components such as condensers, evaporator coils, and line sets. Its soft-drawn, coiled form allows field technicians to cut and bend runs to length without specialized straightening equipment. This tubing is handled and installed by licensed HVAC technicians and refrigeration mechanics working on both new installations and service replacements.
This coiled refrigeration tubing is suited for residential and light commercial HVAC and refrigeration applications where flexible, field-formable copper line is required. Common install scenarios include connecting split-system air conditioners, heat pumps, refrigeration cases, and other systems that require a clean, pressure-rated copper refrigerant line. The coiled format is especially practical in tight mechanical rooms or when routing lines through walls and ceilings where straight lengths are impractical.
Designed as an OEM-style replacement and new-installation copper refrigerant line for residential and light commercial HVAC and refrigeration systems requiring 0.5-inch copper tubing.
Installation of refrigerant tubing must be performed by EPA Section 608 certified HVAC technicians. Always recover or isolate refrigerant before cutting into an existing system. Use a tubing cutter rather than a saw to produce clean, burr-free ends, and ream the cut edge before brazing or flaring to prevent system contamination. All refrigerant line work should comply with applicable local mechanical codes and the system manufacturer's installation requirements.
