HARDLINE #6 X 18in Female/Female U Bend Em

The VINTAGE AIR HARDLINE #6 X 18in Female/Female U Bend Em is a pre-fabricated aluminum refrigerant hard line designed for custom air conditioning and climate control systems. This 18-inch U-bend configuration eliminates the need for field bending, reducing installation time and the risk of kinks or stress fractures that compromise system efficiency. Built from aluminum and fitted with dual 6 AN female O-ring fittings, this hard line delivers reliable performance in demanding automotive, marine, and industrial cooling applications.

The #6 AN specification refers to a 3/8-inch inner diameter, a standard size in high-flow refrigerant systems where pressure drop and flow rate balance is critical. The female O-ring fittings accept 6 AN male connectors and allow quick disconnect or permanent assembly depending on system design. At 0.19 lbs and measuring 20.3 inches in overall bent length, this hard line integrates seamlessly into space-constrained engine bays and equipment enclosures. The natural aluminum finish resists corrosion in moderate environments, though supplemental protective coating is recommended for marine or salt-air applications.

This product serves technicians and fabricators who specify pre-bent hard lines to maintain consistent system geometry and reduce assembly complexity. Classic car restoration shops, aftermarket air conditioning installers, and equipment OEMs rely on pre-formed hard lines to meet tight routing requirements and pass pressure testing without field modification. The VINTAGE AIR HARDLINE series is recognized for consistent wall thickness and precision bending that meets industry standards for refrigerant containment and vibration resistance.

When ordering refrigerant hard line assemblies, verify that the 6 AN female connection matches your system's male fittings and that the 18-inch length and U-bend geometry fit your specific layout. Stock this replacement component for installations requiring exact OEM hard line dimensions or as a standard part for repetitive climate control builds.
