Hardline -6X36in Female /Female U-Bend-Em

The Vintage Air Hardline 6X36in Female/Female U-Bend-Em refrigerant hard line is a pre-formed aluminum refrigerant line assembly designed for air conditioning and refrigeration systems requiring precise routing and quick installation. This 36-inch U-bend configuration features 6 AN female O-ring fittings on both ends, allowing for secure, leak-resistant connections to standard AN-6 ports commonly found in automotive air conditioning systems, marine cooling applications, and custom refrigeration builds.

Constructed from aluminum with natural finish, this hard line measures 0.75 inches in outer diameter and maintains the 36.5-inch length to accommodate mid-size engine bays and equipment enclosures. The pre-formed U-bend geometry eliminates field bending operations, reducing the risk of kinking, work-hardening, or creating weak points in the line that could lead to refrigerant leaks under operating pressure. Female O-ring fittings provide a sealed connection that resists vibration-induced loosening and withstands thermal cycling common in high-demand cooling applications.

This assembly is ideal for hot rod and custom vehicle air conditioning retrofits, marine engine cooling systems, and industrial refrigeration equipment where OEM hard line routing is unavailable or non-standard. The lightweight aluminum construction and straightforward female-to-female connection method simplify installation while maintaining the integrity and pressure rating required for modern refrigerants and blends. Vintage Air's hard line offerings are widely recognized within the automotive cooling retrofit market for consistent manufacturing tolerances and reliable field performance.

SKU VIN125745 ships as a single unit. Verify all port sizes and routing geometry against your system schematic before ordering to ensure proper fitment and compatibility with your compressor, condenser, and receiver-drier ports.
