Description
When you’re running high-pressure fuel or coolant lines, mismatched fittings create weak points that can fail under boost or sustained heat. This Allstar adapter bridges the gap between -10 AN and -12 AN systems, letting you integrate components from different manufacturers or upgrade individual sections without replacing your entire line set. The straight design minimizes turbulence and pressure drop while the black anodized aluminum resists corrosion in engine bays and fuel cells.
