#12 Female x #16 Male Swivel Expander Black

The FRAGOLA #12 Female x #16 Male Swivel Expander in Black is a precision aluminum adapter fitting engineered to connect AN-size hose lines with different port configurations. This straight expander allows seamless integration between a #12 AN female swivel inlet and a #16 AN male outlet, making it essential for hydraulic, fuel, and coolant systems where port size mismatches require a reliable transition. The black anodized aluminum construction provides corrosion resistance and durability across demanding engine bay and fluid delivery applications.

This adapter's swivel design on the female end permits rotational adjustment during installation, eliminating unnecessary stress on hose assemblies and fittings during tight-space fitment. The anodized finish protects against oxidation while maintaining the visual integrity of custom fluid system builds. At 0.15 lbs with compact dimensions (2.05 x 1.55 x 4.1 inches), the fitting integrates cleanly without adding bulk. FRAGOLA's precision manufacturing ensures consistent bore alignment and leak-free sealing when paired with compatible AN hose assemblies and compatible port threads.

Builders and technicians working with custom fuel injection systems, high-performance cooling loops, and hydraulic circuits depend on expander fittings to bridge port incompatibilities without sacrificing system integrity. This adapter is specified for applications where #12 and #16 AN line sizes meet at a single connection point. Verify your existing port threads and hose terminations before purchase to ensure correct AN sizing and compatibility with your specific system configuration.

Individual FRAGOLA adapter fittings are available in multiple AN size combinations to support modular system design. Always use appropriate Teflon thread sealant or thread-locking compound on male ports and confirm proper torque specifications for your application to prevent leaks and ensure long-term reliability.
