AN To NPT Straight -6 x 3/8in

The AN To NPT Straight -6 x 3/8in adapter by Allstar Performance is a precision fluid-line fitting engineered to bridge incompatible port standards in high-pressure hydraulic and fuel systems. This adapter transitions from AN (Army-Navy) male threads to NPT (National Pipe Thread) male connections, making it essential for custom plumbing in racing engines, fuel injection systems, and aftermarket hydraulic assemblies where off-the-shelf components don't align perfectly.

Constructed from lightweight aluminum and finished with black anodized coating, this straight adapter resists corrosion while maintaining durability under sustained pressure cycles. The -6 AN sizing accommodates larger displacement flow rates common in performance applications, while the 3/8-inch NPT port accepts standard industrial fittings. Black anodization protects the aluminum substrate and provides a professional appearance in engine bays and fuel cells. The straight design eliminates flow turbulence at the junction, critical for fuel delivery consistency and system reliability in competition-grade vehicles.

Street rodders, drag racers, and custom fabricators rely on adapters like this AN To NPT Straight -6 x 3/8in to integrate vintage or repurposed components into modern systems. Compatible with both fuel and hydraulic lines operating within standard pressure limits, this fitting simplifies installation when original equipment specifications don't match available inventory. Compact dimensions ensure fitment in tight engine compartments. Proper thread sealant application on NPT connections is recommended to ensure leak-free performance under vibration and thermal cycling.
