#16flare/#16flare Union

The AEROQUIP #16 flare/#16 flare union adapter is a precision hydraulic fitting designed for high-pressure fluid transfer systems where male-to-male connections are required. This straight adapter serves as an essential component in aircraft, automotive, and industrial hydraulic applications where reliable, leak-free connections between two 16 AN male ports are critical. Built to withstand demanding operational pressures and vibration environments, this fitting eliminates the need for additional hose segments or complex adapter chains.

Manufactured from aluminum and finished with blue anodized coating, the 16 AN union provides both corrosion resistance and lightweight construction—key advantages in aerospace and performance applications. The flare-style connection ensures positive sealing through metal-to-metal contact at the fitting faces, eliminating reliance on elastomer seals that can degrade under extreme temperatures or prolonged exposure to aggressive hydraulic fluids. The straight-through design maintains optimal flow characteristics and pressure retention across the connection point, critical for systems operating at sustained high pressures.

Technicians and engineers across military, commercial aviation, and high-performance automotive sectors rely on AEROQUIP fittings for their proven durability and consistency. This adapter is ideal for reconfiguring or extending existing 16 AN hydraulic systems without disrupting line integrity or requiring system depressurization. Installation is straightforward—thread both male connections hand-tight, then complete final engagement with appropriate wrenches to achieve proper seal without over-torquing. Compatible with any standard 16 AN male port, this fitting integrates seamlessly into brake systems, fuel delivery, cooling loops, and pressurized fluid networks.
