AN Reducer #8 Female x #6 Male

The AN Reducer #8 Female x #6 Male (Part Number HF-37608BLK) is a straight-adapter fitting that bridges AN port size differences in high-pressure hydraulic and pneumatic systems. Built from aluminum with black anodized finish, this #8 AN female swivel to #6 AN male adapter enables secure connections between mismatched port sizes commonly found in fuel systems, brake lines, and pneumatic circuits used in tactical vehicles, aircraft ground support, and industrial equipment.

The swivel design on the female end permits directional adjustment during installation, reducing installation stress on mated components and minimizing potential for cross-threading or seal damage. Aluminum construction provides weight savings critical for aerospace and mobile applications, while the black anodized protective coating resists corrosion from moisture, salt spray, and hydraulic fluid exposure. The straight configuration ensures flow path efficiency without dead legs that can trap air or sediment in closed-loop systems.

This adapter is specified for technicians and engineers working with AN/JIC-certified systems where port compatibility becomes critical—fuel cell installation, brake system modifications, pneumatic tool integration, and equipment reconfiguration. Compact at 2.45 x 0.95 x 3.4 inches and weighing only 0.05 lbs, it integrates into confined engine bays and equipment housings without requiring custom fabrication. Each unit ships individually, simplifying inventory management and replacement logistics.

AN (Army-Navy) adapters meet strict aerospace and military fluid-system standards. Size conversion fittings like this reducer are essential stock items for facilities maintaining diverse equipment generations—older systems with #8 ports connecting to newer #6 specifications without requiring complete hose replacement or system redesign.
