Aluminum Plug Kit

The Aluminum Plug Kit (SKU ALL 50830) is a professional-grade dust cap assembly designed to protect AN fittings from contamination during storage, transport, and system maintenance. Built for technicians, mechanics, and hydraulic system professionals, this kit addresses a critical need in fluid power applications where even microscopic particles can compromise seal integrity and system performance. The three-piece configuration covers AN-16 sized connections, the industry-standard diameter for medium-pressure hydraulic and pneumatic systems across aerospace, industrial, and automotive sectors.

Manufactured from aluminum, these plugs deliver durability without the weight penalty or galvanic corrosion issues associated with steel alternatives. The natural finish provides corrosion resistance suitable for general maintenance environments while remaining compatible with standard AN-16 male ports and quick-disconnect couplings. The compact kit dimensions (5.5 × 1.75 × 9.05 inches) and lightweight construction (0.23 lbs) make it portable enough for field kits and mobile maintenance operations, while the three-plug configuration ensures you have spares for simultaneous multi-port protection or replacement of worn caps without workflow interruption.

This kit suits anyone working with AN-16 hydraulic hose assemblies, manifold systems, or quick-connect equipment. Installation requires no tools—plugs hand-fit directly onto AN-16 male ports with finger-tight pressure. Essential for preventing internal contamination before hose installation, troubleshooting system leaks, or storing equipment long-term. Compatible with all standard AN port threads and hose fittings, the aluminum construction ensures longevity in shop, field, and storage environments where reliability cannot be compromised.
