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 designed to connect 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.

Constructed from lightweight aluminum and finished with a black anodized coating, this straight adapter resists corrosion while maintaining durability under sustained pressure cycles. The -6 AN sizing indicates the size of the fitting, while the 3/8-inch NPT port accepts standard industrial fittings. The black anodization not only protects the aluminum substrate but also provides a professional appearance in engine bays and fuel cells.

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. Its straight design helps maintain flow consistency, critical for system reliability in competition-grade vehicles.
