#10 Male to 3/4in NPT Ano-Tuff Adapter

The EARLS #10 Male to 3/4in NPT Ano-Tuff Adapter is a straight adapter fitting designed for custom automotive fluid systems, including fuel lines, coolant circuits, and hydraulic brake setups on modified vehicles. This adapter bridges two different port configurations—a #10 male connection and a 3/4-inch NPT female port—allowing you to integrate components with incompatible threading into a cohesive assembly. Whether you're fabricating a custom fuel rail, upgrading a turbo coolant line, or plumbing a remote oil cooler on a high-performance build, this adapter delivers the flexibility modern engine bay modifications demand.

Constructed from aluminum and finished with EARLS' proprietary Ano-Tuff hard-anodized coating, this adapter resists corrosion and oxidation in harsh underhood environments while maintaining dimensional stability across temperature swings typical of turbocharged and supercharged applications. The straight-thread design eliminates unnecessary flow restrictions and bends, critical for maintaining fuel pressure consistency and minimizing heat buildup in coolant systems. The NPT thread standard ensures proper tapered sealing when wrapped with PTFE tape or combined with appropriate sealant compounds, creating a reliable connection.

This adapter is essential for fabricators, engine builders, and DIY enthusiasts tackling fuel system upgrades, intercooler plumbing, or hydraulic circuit modifications. Its robust construction and specialized finish make it a dependable choice for high-performance applications. With this adapter, you can confidently integrate various components in your automotive projects.
