Product description
This aluminum AN3 to 1/8" NPT adapter makes connecting flare fittings to tapered pipe threads straightforward, offering a durable solution for fluid systems. It suits fuel lines, cooling circuits, and power steering connections where a compact, serviceable join is needed.
Key features
Made from 6061-T6 aluminum with an anodized black finish, the fitting resists corrosion and handles workshop use. The AN side seals at a 37-degree flare angle, while the NPT side uses a 60-degree tapered thread. For leak-free assembly, the manufacturer notes that sealant or PTFE tape is strongly recommended on the NPT end. The adapter tightens and loosens easily with a standard wrench, which speeds maintenance and reduces downtime. 🔧

Where it shines
This adapter performs well when you need a compact transition between AN flare fittings and pipe thread components. It minimizes assembly complexity in tight spaces and keeps replacement simple. Keep in mind that NPT joints rely on sealant for a pressure-tight fit, so factor that into installation and routine checks. 🛠️
Practical tips
When installing, wrap the NPT threads with PTFE tape or apply a suitable thread sealant and tighten to a snug torque following typical fitting practices. If you swap between dissimilar metals or high-vibration environments, inspect the connection periodically for signs of loosening or leakage. ⚠️
