#6 Male to 1/4in NPT 45 Deg Ano-Tuff Adapter

The #6 Male to 1/4in NPT 45 Deg Ano-Tuff Adapter from Earl's Performance is a precision hose fitting engineered for high-performance fuel, oil, and coolant systems in modified vehicles and race applications. This adapter bridges incompatible port sizes and thread types, allowing builders and mechanics to integrate specialized components into custom plumbing configurations without compromising system integrity or flow efficiency. Whether you're upgrading a fuel system on a turbocharged engine, installing remote oil coolers, or routing coolant lines in a tight engine bay, this adapter delivers the reliability demanded by serious automotive enthusiasts.

Constructed with Earl's signature Ano-Tuff anodized aluminum, this fitting resists corrosion, oxidation, and thermal stress while maintaining a lightweight profile essential for performance builds. The 45-degree angle orientation enables space-efficient routing in cramped engine compartments and around complex component layouts, reducing vibration-induced fatigue at connection points. The #6 male inlet threads to a standard 1/4-inch NPT outlet, creating a reliable seal across SAE and NPT porting standards—critical when sourcing components from multiple manufacturers or retrofitting aftermarket systems into OEM-designed platforms.

Professional mechanics and DIY builders rely on Earl's adapters for consistency across fuel injection upgrades, turbocharger installation packages, and custom cooling loops where pressure ratings and thread compatibility cannot be compromised. The compact 2.95-inch length and minimal 0.03-pound weight make integration seamless in weight-sensitive applications and confined spaces. Compatible with automotive cooling systems, fuel delivery networks, and pressurized oil circuits, this adapter is ideal for anyone undertaking comprehensive engine modifications or system integration work.
