-8 Aluminum Dust Plug 20pk

The AEROQUIP -8 Aluminum Dust Plug 20-pack (FBM3657) is a reliable sealing solution for -8 AN hydraulic and pneumatic fittings. These knurled-head aluminum plugs prevent contamination, moisture, and debris from entering unused ports during equipment assembly, maintenance, or storage. Available in a convenient 20-piece set, they're an essential consumable for shops, fleet operations, and field technicians working with hydraulic systems, aircraft systems, or pressurized equipment.

Each plug features a knurled head design that provides secure hand-grip tightening without requiring tools, enabling quick installation and removal in tight spaces or high-frequency swap scenarios. The -8 AN port size (equivalent to 1/2-inch SAE) is common in medium-duty hydraulic lines, fuel systems, and air brake applications. Aluminum construction balances weight savings with adequate mechanical strength for static sealing duty. The natural finish is compatible with standard AN systems and resists minor oxidation in typical industrial environments. At 0.08 lbs per pack, these plugs represent minimal overhead inventory while delivering essential contamination control.

Technicians and maintenance crews rely on dust plugs during equipment teardowns, system diagnostics, and long-term storage to protect against airborne particles and moisture intrusion that can damage seals, pumps, and valves. A 20-pack ensures adequate supply for multiple systems or repeated maintenance cycles without frequent reordering. Whether you're managing agricultural equipment, industrial machinery, aerospace components, or mobile hydraulic platforms, having a stock of properly-sized AN plugs on hand prevents costly downtime and system failures.
