St Alum #4flare/1/8in Pipe

The AEROQUIP St Alum #4 Flare 1/8 Inch Pipe fitting (FCM2001) is a straight adapter designed to connect 4 AN male threads to 1/8 inch NPT male ports. This aluminum fitting features blue anodized protection, making it suitable for fluid power and pneumatic applications where corrosion resistance and lightweight construction are priorities. The adapter maintains compatibility with standard AN flare fittings used across hydraulic systems, brake lines, and fuel delivery networks.

The 4 AN to 1/8 NPT configuration allows technicians to bridge systems using different threaded standards without requiring additional adapters. AEROQUIP's aluminum construction keeps the adapter lightweight—just 0.04 lbs—while the blue anodized finish provides UV and corrosion resistance for outdoor or high-moisture environments. The straight design eliminates bend radius concerns and reduces pressure drop compared to offset adapters, making it ideal for direct port connections where clearance permits.

This fitting serves technicians, mechanics, and engineers working with hydraulic systems, aircraft fluid lines, industrial pneumatics, and custom fluid routing applications. It is particularly valuable in restoration projects, aftermarket system builds, and OEM replacements where legacy equipment uses mixed threaded standards. The NPT port accepts pipe thread fittings, which are common in manifold blocks and gauge connections, while the 4 AN flare end integrates seamlessly into modern modular fluid systems.

AEROQUIP aluminum fittings are widely recognized in motorsports, aviation maintenance, and industrial fluid power applications for reliable thread integrity and consistent fit-up. This adapter is sold individually, allowing you to purchase only what you need for your specific application without excess inventory. Verify compatibility with your system's pressure rating and thread condition before installation.
