Aeroquip FCM5031 90-Degree Aluminum Adapter, -4 AN Male to 1/8 in. NPT Male, Black Anodized

The Aeroquip FCM5031 adapter is designed to connect a -4 AN male flare fitting to a 1/8 in. NPT male port in applications requiring a compact 90-degree change in direction. Manufactured from lightweight aluminum, this fitting provides a practical solution for routing fluid lines in automotive, motorsports, performance, and custom plumbing systems. The black anodized finish adds corrosion resistance and supports a clean, professional appearance.
The 90-degree configuration helps simplify line routing around tight clearances while maintaining a secure connection between compatible AN and NPT components. The -4 AN male side is engineered for use with matching -4 AN female flare fittings, while the 1/8 in. NPT male side installs into a properly tapped female NPT port. As with all tapered pipe thread connections, use an appropriate thread sealant or sealing method compatible with the intended fluid and application, while keeping sealant away from the passage opening.
Designed for reliable installation and long-term service, the Aeroquip FCM5031 combines durable aluminum construction with a black anodized surface treatment. This fitting is sold individually and is suitable for custom fuel, oil, coolant, and other fluid-routing systems when the material, thread type, pressure rating, and fluid compatibility meet the requirements of the application. Verify connection specifications before installation to ensure proper fit and performance.
