Fitting Dry Sump Square Base 8an Male

The Moroso Fitting Dry Sump Square Base 8AN Male is a precision aluminum adapter designed for external oil pump systems in dry sump applications. This component serves as a critical connection point in high-performance engine oil circulation systems, enabling reliable fluid transfer between pump outlets and main engine galleries. The 8AN male fitting size is industry standard for serious performance and racing builds where oil system integrity directly impacts engine longevity.

Constructed from aluminum and finished in natural (uncoated) form, this fitting combines lightweight construction with proven durability in demanding cooling and lubrication circuits. The square base design provides a stable mounting platform and ensures repeatable orientation during installation. At 8AN (AN8) specification, the fitting accommodates standard braided hose systems and delivers the flow capacity required for modern external oil pump configurations where bypass pressure and volume control are essential to engine protection.

This adapter is purpose-built for dry sump systems—a configuration common in race cars, high-powered street machines, and performance engines where oil capacity, circulation, and scavenging demands exceed standard wet-sump capability. Dry sump setups require precision fittings that maintain leak-free connections under sustained pressure and temperature cycling. Moroso's dry sump components are engineered to meet those exacting standards, making this fitting an essential element for builders constructing reliable external oil systems.
