#4 To 7/16-24 Inverted Steel Adapter

The AEROQUIP #4 to 7/16-24 Inverted Steel Adapter (FCM2930) is a straight-through hydraulic and pneumatic fitting designed to connect 4 AN (Army-Navy) male ports to 7/16-24 inverted flare male threads. Manufactured in steel with zinc oxide plating, this adapter is engineered for hardline applications where corrosion resistance and reliable pressure sealing are essential. It serves as a critical component in fluid power systems found in aerospace, industrial machinery, marine equipment, and high-performance automotive applications.

The inverted flare design on the 7/16-24 side creates a robust, leak-resistant seal suitable for high-pressure environments where traditional straight threads may fail under vibration or thermal cycling. The 4 AN male connection provides standardized compatibility with AN hose fittings and other AN-threaded components widely used in hydraulic systems. Steel construction with zinc oxide coating delivers enhanced durability against corrosion compared to uncoated alternatives, particularly in humid or salt-air conditions. The compact dimensions and minimal weight (0.11 lbs) make it suitable for space-constrained installations where bulk matters.

This adapter is specified for technicians, engineers, and equipment manufacturers assembling or servicing hardline hydraulic circuits that require mixed thread standards. It is particularly valuable in restoration work, custom fabrication, and OEM assembly where existing equipment uses legacy 7/16-24 ports but modern systems rely on standardized AN connections. The AEROQUIP brand carries recognized credibility in fluid power fittings, and the FCM2930 maintains the quality standards expected in mission-critical applications.
