12AN Female to 16AN Male Expander Black

The 12AN Female to 16AN Male Expander Black by REDHORSE PERFORMANCE is a precision hydraulic fitting adapter designed for builders and mechanics who need to step up hose line sizes in tight underhood packaging or fuel system configurations. This expander fitting solves a critical plumbing problem: connecting smaller-diameter supply or return lines to larger-diameter system components without compromising flow integrity or requiring custom fabrication. Whether you're building a high-flow fuel system, upgrading cooling circuits, or routing brake fluid in a custom chassis, this adapter provides a reliable transition that maintains system pressure and eliminates leaks at the connection point.

Engineered from aerospace-grade materials, the 12AN to 16AN expander features a black-anodized aluminum body that resists corrosion and integrates seamlessly into modern performance plumbing schemes. The female port accepts standard 12AN hose assemblies, while the male port delivers a full 16AN connection, eliminating stepped transitions and bottlenecks. REDHORSE PERFORMANCE's design ensures that internal passages are optimized for maintaining laminar flow characteristics, which is critical for fuel injection systems running above 100 psi or cooling systems experiencing rapid thermal cycling.

This adapter is ideal for automotive enthusiasts and professionals looking to enhance their vehicle's performance and reliability. Its compact design allows for installation in space-constrained areas, making it a versatile choice for various applications. With its robust construction and precise engineering, the 12AN Female to 16AN Male Expander is a dependable solution for anyone needing to connect different hose sizes in their hydraulic systems.
