Description
When you’re running custom fuel, coolant, or pneumatic lines in your race engine bay, you need reliable adapters that won’t leak under pressure. This Allstar Performance AN-to-NPT straight adapter bridges the gap between modern -4 AN hose systems and traditional NPT port configurations, giving you the flexibility to integrate both line types into a single, cohesive plumbing setup. Black anodized aluminum construction resists corrosion while keeping weight minimal—essential for any serious build.
