618-08-08-BLK -8 male to 1/2" tube adapter

Speedflow 618-08-08-BLK | -8 AN Male to 1/2" Tube Adapter – Black

The Speedflow 618-08-08-BLK is a precision-engineered -8 AN male to 1/2" tube adapter designed for high-performance fuel, oil, and cooling line applications. Part of the Speedflow 618 Series, this compression-style fitting converts steel or aluminium hard line tubing to AN fittings with a secure, leak-free seal.

How It Works

This adapter uses a compression olive (ferrule) system to grip and seal the tubing without the need for flaring. Simply insert the tube, tighten the fitting, and the olive compresses to form a reliable, vibration-resistant seal — ideal for motorsport and performance street applications where reliability is non-negotiable.
