DEWHEL 2-Pack AN6 To 3/8 NPT Adapter Fittings - Black Anodized Aluminum Straight Union Flare Adapters

For the car enthusiasts and mechanics working on fuel systems, turbo kits, or cooling systems, these DEWHEL AN6 to 3/8 NPT adapters are absolute must-haves! This 2-pack gives you everything you need to connect AN6 flare fittings to 3/8 NPT threaded ports seamlessly. The black anodized aluminum construction looks professional and provides excellent corrosion resistance while remaining lightweight. The 37-degree flare sealing angle on the AN6 side creates a perfect seal without crushing, while the NPT side uses standard 60-degree tapered threads. Important note: you absolutely need to use Teflon tape or thread sealant on the NPT side to prevent leaks - don't skip this step! The quality machining is evident in the clean threads and precise tolerances. These adapters handle various fluids like fuel, oil, water, coolant, transmission fluid, E85, and methanol without degrading. Whether you're building a custom fuel system, installing a turbo kit, setting up oil coolers, or any project that requires converting between AN flare and NPT threads, these adapters make the connection clean and reliable. The straight union design works in tight spaces where angled fittings won't fit. Having a couple of these in your toolbox means you're always prepared for those unexpected connection challenges during builds or repairs. The black finish looks slick on any engine bay or fluid system, giving your project that professional, finished appearance. If you work with AN fittings regularly, these adapters will quickly become one of your most-used components.
