Machined from 6061-T6 aluminum and finished with a black anodized surface, each piece uses a 37° flare seal on the AN side and a 68° taper on the NPT side; because NPT threads rely on taper sealing, thread sealant or PTFE tape is recommended to prevent leakage. The package of four is intended for performance automotive systems where light weight, corrosion resistance, and repeatable joins matter.\n\n\u003ch3\u003eHow do these adapters join AN and NPT systems reliably?\u003c\/h3\u003e\n\u003cp\u003eEach adapter combines two sealing philosophies: a machined 37° flare for the AN side and a tapered 68° NPT thread for pipe-side sealing. The flare provides a metal-to-metal crush seal when paired with a matching flare-seat, while the NPT side seals by thread interference and requires a sealing compound.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAN side: 37° flare geometry for a predictable, reusable metal seal.\u003c\/li\u003e\n  \u003cli\u003eNPT side: 68° tapered pipe thread that seals with thread sealant or PTFE tape.\u003c\/li\u003e\n  \u003cli\u003eMaterial: 6061-T6 aluminum resists corrosion and keeps mass low.\u003c\/li\u003e\n  \u003cli\u003eFinish: black anodize protects the surface and reduces galling.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat systems and fluids are these fittings suitable for?\u003c\/h3\u003e\n\u003cp\u003eThese adapters are commonly used in fuel delivery, coolant plumbing, power steering lines, and other low- to moderate-pressure automotive applications.
