P/C #6 Flare Cap

The RUSSELL P/C #6 Flare Cap (Part #661963) is an AN-spec aluminum flare cap designed for use with 6 AN hydraulic and pneumatic line systems. This black anodized fitting serves as a protective closure for 6 AN ports and is essential for maintaining system integrity during assembly, storage, and operation. The flare cap prevents contamination, fluid loss, and unwanted air entry in pressurized systems, making it a critical component in aerospace, automotive, and industrial fluid power applications.

Constructed from aluminum and finished in black anodize, this cap meets AN (Army-Navy) specifications for standard flare fittings. The 6 AN designation indicates compatibility with hoses and ports rated for six-pitch-diameter connections, commonly found in fuel systems, coolant lines, and air brake circuits. The anodized finish provides corrosion resistance and extended service life, particularly in environments where exposure to moisture, salt air, or chemical vapors is a concern. RUSSELL is a recognized manufacturer of fluid power fittings and adapters across multiple industries, ensuring specification compliance and reliable performance.

Technicians, system integrators, and maintenance professionals rely on flare caps during installation, testing, and repairs of pressurized systems. Whether capping off unused ports during rig assembly, protecting connections during transport, or replacing a damaged cap in the field, this AN-spec fitting delivers dependable closure. The compact, lightweight design (0.06 lbs) makes it easy to stock multiple units for emergency repairs and system modifications.

Sold as a single unit, this cap is an essential consumable inventory item for shops, fleets, and facilities that maintain hydraulic or pneumatic equipment. Verify compatibility with your system's 6 AN flare ports before installation to ensure proper fit and seal.
