-3 Plastic Caps 20pk

The ALLSTAR PERFORMANCE -3 Plastic Caps 20pk (SKU ALL 50801) is an essential protective solution for AN (Army-Navy) threaded fittings commonly found in high-performance fuel systems, brake lines, and hydraulic assemblies. Designed for technicians, engine builders, and automotive enthusiasts, these dust caps prevent contamination of critical fluid system connections during storage, transport, and maintenance operations. A complete 20-pack ensures you have adequate coverage for multiple systems or future projects without reordering.

Engineered from durable plastic material, the -3 AN dust caps feature a bright red finish for quick visual identification of -3 AN port sizing on your fluid system components. The compact design—measuring 4 × 0.65 × 7.05 inches with a featherweight profile of just 0.06 lbs—allows convenient storage in toolboxes or pit kits without bulk. Plastic construction resists corrosion and chemical degradation, making these caps ideal for fuel, coolant, and brake applications where metal caps might corrode or react with system fluids over time.

Professional mechanics, race teams, and DIY builders rely on AN dust caps to maintain system integrity during assembly, disassembly, and long-term vehicle storage. Whether you're protecting fuel injector ports on a carbureted engine, sealing brake line connections on a custom chassis, or safeguarding transmission cooler fittings, these caps eliminate the risk of dirt, debris, and moisture ingress that could compromise performance or create dangerous system leaks. The 20-pack quantity makes this set an economical choice for shops maintaining multiple vehicles or for builders working on several projects simultaneously.
