Product Overview

The EVIL ENERGY 6AN flare to M12 x 1.25mm male fitting adapter is a compact, durable bridge between two common connection standards. Crafted from 6061-T6 aluminum with a reliable NBR O-ring, this dual-adapter set is designed to support clean, repeatable assemblies in automotive and performance applications. Its understated, precision-built form helps you organize lines in tighter spaces without compromising function.

Design and Materials

Built for strength without excess weight, the 6061-T6 aluminum body delivers solid rigidity while staying light enough for mobile installations. The AN side uses a 37-degree flare seat for a tight, high-integrity seal, paired with a separate O-ring on the metric side to help seal against vibration and temperature swings. The overall construction emphasizes smooth threads and dependable fit, reducing cross-threading risk during installation.
