Machined from 6061-T6 aluminum and finished with a black anodized coating, each straight fitting is designed for strength and light weight. Because NPT threads seal with taper, using a thread sealant or PTFE tape on the NPT side is recommended to achieve leak-free connections.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this adapter join AN and NPT connections reliably?\u003c\/h3\u003e\n\u003cp\u003eThe adapter mates an AN8 male flare (sealed by a 37° cone) to a 3\/8\" NPT pipe thread (sealed by a tapered 68° thread), allowing different hose and port types to be connected without custom fabrication. Proper installation relies on the flare seating correctly and the NPT thread being sealed with an approved compound.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAN8 male end uses a precision 37° flare seating surface for a metal-to-metal seal.\u003c\/li\u003e\n  \u003cli\u003e3\/8\" NPT side uses standard tapered threads — requires sealant or PTFE tape.\u003c\/li\u003e\n  \u003cli\u003eStraight-through geometry preserves flow and minimizes turbulence.\u003c\/li\u003e\n  \u003cli\u003eWrench flats allow secure tightening and easy removal.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials and finishes are used, and why do they matter?\u003c\/h3\u003e\n\u003cp\u003eEach fitting is milled from 6061-T6 aluminum, a common alloy chosen for its combination of strength, machinability, and resistance to corrosion.
