EVIL ENERGY 6AN Flare to M10 x 1.0mm Adapter – Aluminum 6061-T6, 2PCS

Overview

Meet the EVIL ENERGY 6AN flare to M10 x 1.0mm adapter, a durable two-piece connector designed for performance lines in automotive and light industrial systems. The AN side uses a precise 37-degree flare seat to help establish a secure, glass-smooth seal when mated with compatible flare fittings, while the metric port seals with an elastomer O-ring to minimize seepage in dynamic conditions.

Built to withstand the rigors of engine compartments, this adapter blends a lightweight aluminum body with a robust O-ring. The combination reduces weight without sacrificing rigidity, making it a sensible upgrade for tight routing and rugged service. A two-piece construction supports straightforward assembly and service, so you can swap or reseal components with minimal downtime.
