Description
When you’re building or upgrading a high-performance fuel, coolant, or brake system, mismatched AN fittings create weak points that can lead to leaks or catastrophic failure under pressure. This Fragola #4 x 3/8-24 adapter bridges the gap between larger and smaller line sizes, giving you the flexibility to run optimal hose diameters throughout your system without compromises. Black anodized aluminum construction ensures durability while maintaining a clean, professional appearance in the engine bay.
