#16 Female x #12 Male Swivel Reducer Black

The FRAGOLA #16 Female x #12 Male Swivel Reducer Black (part number 497217-BL) is a precision aluminum AN adapter fitting designed for fluid transfer systems where line size reduction is required. This straight-design reducer connects a #16 AN female swivel port to a #12 AN male connection, making it essential for high-pressure hydraulic, fuel, or coolant applications where space or flow management demands a step-down in line diameter.

Constructed from aluminum with black anodized finish, this adapter provides corrosion resistance and durability in demanding environments. The swivel design on the female end allows for easier installation and removal without requiring tool rotation on the connected component, reducing stress on adjacent fittings and hoses. The straight configuration ensures minimal turbulence and pressure drop through the reducer, critical in systems where flow efficiency directly affects performance. Weighing just 0.21 lbs, the compact footprint (1.95 x 1.65 x 4.25 inches) fits tight installation spaces common in automotive, aircraft, and industrial hydraulic setups.

This fitting is ideal for engineers and technicians assembling or modifying fluid systems where AN standard connectors are required. Whether upgrading fuel delivery lines, managing coolant circuits, or integrating hydraulic subsystems, the #16-to-#12 step-down reducer bridges common line size mismatches while maintaining system integrity. Buyers should verify AN port compatibility on both source and destination components before installation.

FRAGOLA adapters are widely recognized in performance and industrial applications for consistent quality and reliable seal performance. Each unit is sold individually, allowing technicians to order exactly the quantity needed for their specific project requirements.
