#16 An Cap Aluminum

The AEROQUIP #16 AN Cap Aluminum (FCM3744) is a precision hydraulic fitting cap designed for high-pressure fluid systems in aerospace, industrial, and mobile equipment applications. This blue anodized aluminum cap seals AN-16 (1-inch) ports, protecting connection points from contamination and fluid loss when lines are disconnected or capped during maintenance and assembly. The lightweight aluminum construction combined with anodized corrosion protection makes it an efficient choice for systems requiring frequent serviceability without sacrificing reliability or durability.

Engineered to AEROQUIP's exacting standards, this AN fitting cap features proper thread pitch and sealing geometry critical for maintaining system integrity. The blue anodized finish provides corrosion resistance in challenging environments—particularly important for aircraft hydraulic systems and equipment exposed to moisture or salt spray. At just 0.18 lbs, the minimal weight is significant in aerospace applications where every ounce impacts fuel efficiency and payload capacity. The compact 3.55 x 1.75 x 4.85-inch profile ensures compatibility with standard rack spacing and hose routing in production aircraft and industrial hydraulic layouts.

This cap is essential for maintenance technicians, avionics shops, and hydraulic system assemblers who need genuine OEM or equivalent components that meet military and civilian aviation standards. Keeping a supply of AN caps on hand prevents contamination-related system failures and reduces downtime during routine service. The AEROQUIP brand is recognized throughout aerospace and heavy equipment sectors for consistent manufacturing quality and adherence to published specifications, making this cap a trusted choice for critical hydraulic applications where system performance and safety are non-negotiable.
