#4 90 Deg Crimp Fitting

The AEROQUIP #4 90 Degree Crimp Fitting (FBM4131) is a precision hose end connector designed for high-pressure hydraulic and fluid power systems commonly found in tactical vehicle platforms, aircraft ground support equipment, and mobile command installations. This 90-degree aluminum fitting accommodates 4 AN hose with crimp-style termination, providing a compact directional change in confined mounting spaces where straight-run configurations are impossible.

The 4 AN hose crimp-to-4 AN female port configuration ensures compatibility with standard military and industrial hydraulic systems. Aluminum construction balances weight reduction with adequate strength for moderate-pressure applications, while the red and silver finish provides visual distinction for circuit identification—a critical safety feature in complex multi-system environments where color-coded hydraulic lines prevent cross-system contamination. The compact 0.75-inch width and minimal profile allow installation in tight equipment bays where bulkier right-angle adapters would create interference.

This fitting serves field maintenance operations, mobile hydraulic system repair, and preventive equipment service on platforms where crimp-style hose terminations are standard. Operations and logistics personnel select AEROQUIP fittings for their established reliability in military-specification fluid power systems. The 90-degree elbow configuration solves routing constraints without requiring additional adapter chains that introduce failure points and pressure drop.

AEROQUIP remains the primary OEM supplier for U.S. military vehicle hydraulic systems, and this fitting maintains the precision tolerances required for those applications. Direct replacement and field-repair inventory roles make this connector essential for maintenance teams operating far from logistics hubs.
