Blkhd Union #4flare/#4fl

The Blkhd Union #4flare/#4fl bulkhead fitting from AEROQUIP is a precision hydraulic connector designed for reliable pressure-tight seals at bulkhead panel transitions. This fitting is ideal for industrial, aerospace, and automotive hydraulic applications where space constraints or panel-mounted configurations are essential. Technicians and system integrators utilize bulkhead fittings to streamline assembly and maintain system integrity.

Constructed from high-grade aluminum, the Blkhd Union #4flare/#4fl features dual 4 AN male ports—one for external hose connection and one for internal manifold or component mounting. The straight configuration minimizes pressure loss and turbulence, which is critical for maintaining system efficiency. AEROQUIP's manufacturing standards ensure consistent 37° flare seat engagement, creating a dependable seal that resists vibration-induced loosening.

This compact fitting (2.35 × 1.1 × 3.7 inches, 0.12 lbs) integrates seamlessly into custom hydraulic panels, mobile equipment, and OEM manifold assemblies where standard external couplings are impractical. Installation requires a standard wrench or flare nut wrench—no specialized tools needed. The anodized finish provides corrosion resistance suitable for outdoor use.
