The AN side seals on a 37° flare while the NPT side relies on tapered threads; the adapter’s black anodized finish improves corrosion resistance and gives a professional appearance. Designed for wrench installation, these fittings are intended for use in automotive and performance setups where reliable steering of fluids and compact routing matter.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this adapter connect 4AN plumbing to a 1\/8\" NPT port?\u003c\/h3\u003e\n\n\u003cp\u003eThe adapter couples a 4AN (7\/16-20 UNF flare) male flare fitting to a male 1\/8\" NPT tapered thread at a 90° angle, providing a secure mechanical joint on the AN side and a tapered-thread seal on the NPT side. Because NPT relies on thread tapering for the seal, using a thread sealant or PTFE tape at the NPT end is recommended for leak-free performance.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eAN side: 4AN (7\/16-20 UNF) with standard 37° flare face.\u003c\/li\u003e\n  \u003cli\u003eNPT side: 1\/8\" male tapered thread for pipe-style ports.\u003c\/li\u003e\n  \u003cli\u003eAngle: 90° elbow for tight routing and clearance management.\u003c\/li\u003e\n  \u003cli\u003eInstallation: fit with appropriate wrench; use sealant on NPT threads.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials and finish are used, and why do they matter?\u003c\/h3\u003e\n\n\u003cp\u003eEach adapter is machined from 6061-T6 aluminum and finished with black anodizing. 6061-T6 balances strength and weight, while anodizing increases surface hardness and corrosion resistance—useful where fittings are exposed to fuel, coolant, or road elements.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eBase material: 6061-T6 aluminum for light weight and mechanical durability.\u003c\/li\u003e\n  \u003cli\u003eFinish: black anodized surface for corrosion protection and consistent appearance.\u003c\/li\u003e\n  \u003cli\u003ePrecision machining: accurate thread and flare sealing faces for proper fitment.\u003c\/li\u003e\n  \u003cli\u003ePack count: sold as a two-piece set for multiple connections or spares.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhere will this elbow adapter typically be used?\u003c\/h3\u003e\n\n\u003cp\u003eApplications include fuel lines, cooling circuits, power steering plumbing, vacuum or sensor ports, and other low- to medium-pressure fluid pathways in automotive and motorsport installations.

Because the NPT side seals via tapered threads rather than a flare face, add PTFE tape or a pipe-thread sealant before final assembly to ensure a leak-free joint.
