-16 Aluminum Plugs 10pk

The -16 Aluminum Plugs 10pk from ALLSTAR PERFORMANCE are essential hose and fuel line fittings designed for serious automotive builders and engine tuners working with high-flow fuel systems, coolant circuits, and pressurized applications. These AN (Army-Navy standard) -16 connectors provide a reliable, leak-free interface in performance engines where precision plumbing directly impacts reliability and safety. Whether you're assembling a custom fuel system, upgrading your cooling loop, or building a street or race engine, having quality aluminum AN fittings in your shop ensures you can confidently thread together critical fluid pathways without improvisation.

Aluminum construction offers a significant weight advantage over steel fittings while maintaining excellent strength and corrosion resistance—critical in modern engine bays where every pound counts and galvanic compatibility matters. The -16 designation refers to the hose ID (approximately 1 inch), making these fittings compatible with standard -16 AN hose, tubes, and adapters found in fuel, oil, and coolant systems. ALLSTAR PERFORMANCE's aluminum plugs feature precision-machined threads and seat geometry that create a consistent, repeatable seal when paired with compatible -16 AN fittings and hose assemblies. The 10-pack format means you'll have adequate stock for multi-port applications, manifolds, and future system modifications without ordering multiple kits.

These plugs are ideal for blocking unused ports on fuel rails, manifold headers, and distribution blocks during system configuration or troubleshooting. Engine builders, fabricators, and DIY enthusiasts benefit from keeping a diverse set of AN plugs on hand—they're indispensable when testing systems, converting from carbureted to fuel-injected platforms, or adapting aftermarket fuel system components. Ensure all mating surfaces are clean and use appropriate AN thread sealant or PTFE tape to guarantee leak-free operation under pressure. Compatible with any standard -16 AN female port, these plugs integrate seamlessly into racing fuel systems, drag cars, street rods, and performance trucks.
