16AN Female - 12AN Male Reducer Black

The 16AN Female to 12AN Male Reducer in Black from REDHORSE PERFORMANCE is an essential fitting for custom fuel, coolant, and hydraulic system plumbing in high-performance vehicles. This adapter bridges two different AN (Army-Navy) line sizes, allowing technicians and builders to connect 16AN hose assemblies to 12AN ports or components without compromising flow integrity or system reliability.

Manufactured from aluminum alloy with a black anodized finish, the 16AN Female to 12AN Male Reducer maintains structural integrity under high pressure while resisting corrosion in engine bay environments. The precision-machined threads ensure a leak-free seal when paired with compatible hose ends and fittings, critical for fuel delivery systems operating at 40+ PSI or coolant circuits under thermal stress.

This fitting is ideal for builders transitioning between late-model OEM 16AN fuel rails and 12AN pump or regulator ports, or for custom applications where component sourcing requires mixed line sizes. REDHORSE PERFORMANCE's reputation for dimensional accuracy means this reducer will thread smoothly without cross-threading, a common issue with inferior aftermarket adapters that can damage expensive AN fittings.
