Union Adapter Fitting; S ize -12 AN x -12 AN

The VIBRANT PERFORMANCE Union Adapter Fitting in -12 AN x -12 AN size is a precision-engineered straight adapter designed to join two male AN fittings of identical size. Constructed from aluminum and finished in black anodize, this adapter is engineered for high-flow hydraulic and fuel systems where direct, leak-free connections are essential. The 12 AN port size handles substantial fluid transfer rates, making it suitable for high-performance automotive, marine, and industrial applications requiring reliable plumbing solutions.

The aluminum construction paired with black anodized protection provides corrosion resistance and durability in demanding environments, from engine bays exposed to heat and moisture to offshore marine installations. The male-to-male configuration eliminates the need for intermediate fittings when connecting two hose assemblies with matching 12 AN male ends. VIBRANT PERFORMANCE maintains strict tolerances on ANJ (AN joint) threads to ensure proper sealing without over-torquing, a critical factor in systems operating at elevated pressures where thread galling or leakage can compromise performance.

This union adapter is ideal for fabricators, restoration shops, and performance builders who need to extend or reconfigure existing hydraulic and fuel line runs without replacing full hose assemblies. It serves as a practical solution when OEM-length hoses don't fit custom engine bay layouts, chassis modifications, or retrofit installations. The compact 3.6 x 3.6-inch footprint and minimal weight (0.11 lbs) ensure minimal packaging impact in space-constrained applications.

Within the AN fitting ecosystem, the -12 size represents a popular middle ground—larger than -8 AN but smaller than -16 AN—balancing flow capacity with compact size. This adapter is a core component for anyone standardizing their fuel, coolant, or hydraulic systems to AN specifications, offering quality and precision expected from VIBRANT PERFORMANCE's motorsport-focused product line.
