-12 Aluminum Dust Cap 10pk

The AEROQUIP -12 Aluminum Dust Cap 10-pack (FBM3652) provides reliable protection for -12 AN threaded hydraulic and pneumatic fittings. These aluminum dust caps seal open ports during storage, transport, and between service intervals, preventing contamination that can compromise system performance. Lightweight at just 0.07 lbs per pack, this 10-piece set offers economical coverage for shops, fleet maintenance operations, and industrial applications where multiple connections require simultaneous protection.

Each cap is constructed from natural aluminum, selected for its corrosion resistance and non-reactive properties with hydraulic fluids and system components. The -12 AN size conforms to JIC (Joint Industry Conference) standard threading, ensuring compatibility with AEROQUIP and equivalent -12 AN ports. The natural finish resists oxidation while remaining visible for quick visual inventory. Compact dimensions (3.35 x 1.4 x 4.7 inches for the full pack) make storage efficient on shelves or in technician kits.

This 10-pack is designed for facilities managing multiple hydraulic circuits, mobile equipment fleets, or manufacturing environments where dust caps see regular rotation. Bulk packaging reduces per-unit cost compared to single caps while ensuring replacements are always on hand. Technicians appreciate having dedicated caps for each connection point, reducing the time spent locating lost covers during system maintenance or troubleshooting. AEROQUIP's reputation for quality fittings extends to these essential protective accessories.

AN hydraulic systems demand consistent attention to cleanliness standards. Port contamination can introduce particles, moisture, or air into circuits, causing actuator drift, seal degradation, or complete system failure. Using proper dust caps during downtime is a cost-effective preventive measure that extends seal life and reduces diagnostic time on the next startup. The -12 AN standard covers moderate-flow applications common in industrial equipment, mobile hydraulics, and instrumentation systems.
