Blkhd Union #12flr/#12fl

The AEROQUIP Blkhd Union #12flr/#12fl is a straight bulkhead fitting engineered for high-pressure hydraulic and pneumatic systems where two 12 AN male ports must connect through a panel or firewall. Designed for professional technicians, military equipment builders, and industrial hydraulic specialists, this fitting delivers the reliability required in mission-critical applications. Bulkhead unions isolate internal system pressure from external environments while maintaining a sealed, leak-free connection—essential in aerospace, automotive, and tactical equipment where fluid integrity cannot be compromised.

Manufactured from steel and finished with zinc oxide plating, the Blkhd Union #12flr/#12fl resists corrosion and oxidation in harsh operational environments. The straight design eliminates flow turbulence, reducing pressure drop and heat generation during extended use. Both ports accept 12 AN male connections, allowing seamless integration into standardized hydraulic systems without adapter chains. Zinc oxide coating protects against moisture and salt spray exposure, making this fitting suitable for both indoor industrial settings and outdoor tactical deployments. The compact footprint (3.55 x 1.75 x 5.25 inches) and modest weight of 0.63 lbs ensure minimal system impact while maintaining full structural integrity under rated pressure.

Professionals working with 12 AN hydraulic systems—from military vehicle maintenance to custom aircraft builds—rely on AEROQUIP bulkhead fittings to safely route hoses through firewalls and compartment barriers. Installation requires straightforward port engagement with standard 12 AN connectors; no special tools beyond a wrench are needed for setup. This fitting pairs seamlessly with existing 12 AN hose assemblies, adapters, and quick-disconnects, making it an ideal replacement or upgrade component. Verify panel thickness compatibility before installation to ensure proper seal engagement and long-term performance in your specific application.
