Fitting Adpt 10an Female To 5/8 Tube Compression

The Fitting Adpt 10AN Female To 5/8 Tube Compression by MOROSO (MPN 65355) is a precision hydraulic adapter designed for custom fuel system, coolant line, and brake line applications where reliable fluid transfer is critical. This straight-configuration compression fitting bridges the gap between 10 AN female ports and 5/8-inch tubing, making it essential for hot rodders, custom builders, and performance enthusiasts who demand leak-free connections under pressure. Whether you're assembling a custom fuel system or upgrading brake lines in a modified vehicle, this adapter provides the secure, repeatable seal that professional-grade applications require.

Constructed from aluminum and finished in black anodized coating, this fitting resists corrosion while maintaining a lightweight profile ideal for performance builds. The compression design creates a mechanical seal when torqued properly, eliminating the need for thread sealant tape and providing superior vibration resistance compared to threaded connections alone. The 10 AN female port accepts standard AN hose ends or male adapters, while the 5/8-inch tube compression end accommodates rigid or flexible tubing commonly found in motorsports fuel systems and hydraulic applications. MOROSO's proven manufacturing ensures consistent bore tolerances and reliable performance across thousands of temperature and pressure cycles.

This adapter is particularly valuable for builders transitioning between AN-style hose fittings and traditional tube compression systems, or when mixing component standards in a unified fluid distribution network. Installation requires proper tube preparation—clean, burr-free cuts and appropriate torque specs—to achieve optimal seal integrity. Compatible with fuel, oil, coolant, and brake fluid systems operating within AN-standard pressure ratings, this fitting is a staple in vintage restoration projects, street rod builds, and professional race car fabrication where system integrity cannot be compromised.
