This LD+ 5440 refrigerant line tubing provides a single run of 3/4-inch nominal diameter material, extending 300 feet in length. It is designed for use in HVAC/R systems where individual refrigerant lines are required for custom installations, large-scale projects, or extending existing line sets. This bulk tubing allows for significant flexibility in creating precise refrigerant pathways to connect various system components.
HVAC technicians and contractors often require long rolls of tubing for commercial projects, multi-zone systems, or when standard pre-fabricated line sets do not meet specific length or configuration needs. This 300-foot roll of 3/4-inch tubing is ideal for such scenarios, enabling professionals to cut and flare lines to exact specifications for liquid or suction applications, depending on system design.
Choosing the correct diameter and length of refrigerant tubing is crucial for maintaining system efficiency and preventing pressure drops over long runs. This product supports a range of commercial and large residential HVAC/R applications, offering a reliable component for refrigerant conveyance. Professional installation is essential to ensure proper sealing and system performance.
