Female to Male Extender Fitting; Size -12AN

The female to male extender fitting size -12AN is a straight adapter designed to connect two AN-port hydraulic or pneumatic lines with a 1.5-inch separation. This compact extender serves as a critical component in high-performance fluid systems where direct connection is impractical or where line routing requires intermediate spacing. Engineers and technicians rely on these adapters in racing fuel systems, brake lines, transmission coolers, and industrial pneumatic applications where precise fluid routing and leak-free connections are non-negotiable.

Constructed from aluminum and finished in black anodize, this fitting combines lightweight durability with corrosion resistance—essential properties for underhood and exposed mounting environments. The straight-through design eliminates flow restrictions while the 12AN designation ensures compatibility with standard aviation-style quick-disconnect couplers and hose fittings rated for -12 (3/4-inch) nominal bore. Black anodizing provides both aesthetic consistency in custom builds and protective oxidation that extends service life in salt-spray, moisture-rich, and chemically aggressive conditions. Each unit measures 1.5 inches in length with a compact footprint of 3.54 x 1.5 x 6.3 inches and weighs only 0.11 pounds, making it ideal for weight-sensitive installations.

This extender fits seamlessly into custom fuel systems, nitrous oxide distribution networks, and precision cooling circuits where OEM routing does not accommodate factory hose paths. Installation requires only standard AN wrench sizes and compatible -12AN hose or line assemblies. Installers and fabricators benefit from the straightforward male-to-female configuration, which reduces adapter stacking and potential leak points while maintaining full flow capacity for high-CFM or high-GPM applications. Whether building a race engine bay or retrofitting hydraulic controls, the female to male extender fitting size -12AN delivers reliable performance without compromise.
