Russell Performance -4 AN Flare to 10mm x 1.0 Metric Thread Adapter (Endura)

Russell is known for making a wide range of fittings that help you connect different fluid systems. This adapter fitting is a great example, letting you connect a -4 AN (Army-Navy standard) hose end to a component with a 10mm x 1.0 metric thread. It’s a common need when you’re working on custom fuel systems, oil lines, or other fluid transfer setups where you need to adapt between AN and metric connections.

This fitting is precision machined from 6061-T6 aluminum, making it lightweight but still strong enough to handle maximum operating pressures. The Endura finish gives it a clean look that complements your hose installation. It’s designed to create a positive seal, so you don’t have to worry about leaks in your system.
