#6 Male to 3/8in Alum Tubing Adapter

The #6 Male to 3/8in Aluminum Tubing Adapter is a precision fitting designed for custom fuel, oil, and coolant line routing in high-performance engine builds and modified vehicle systems. This adapter is essential for integrating aftermarket fuel injection systems, external oil coolers, turbocharger intercooler setups, or custom cooling loops where AN6 male connections must transition to 3/8-inch aluminum tubing.

Constructed from lightweight aluminum, this adapter offers the durability required for motorsport and street performance applications where weight savings and thermal performance matter. The #6 AN male thread provides a secure, leak-free connection with proper sealing tape or thread sealant, while the 3/8-inch aluminum tubing port accepts standard DOM or aluminum hard line stock. The compact design measures 2.7 inches in length and weighs just 0.04 pounds, ensuring minimal obstruction in tight engine compartments.

Ideal for engine bay fabricators, turbo kit installers, and serious DIY builders, this adapter serves dual-purpose builds where reliable connections are crucial. It is important to ensure proper sealing for both fuel and coolant applications to prevent leaks. This adapter is a valuable addition for anyone looking to enhance their vehicle's performance and aesthetics.
