#6 Str Ano-Tuff Auto- Mate

The #6 Str Ano-Tuff Auto-Mate by EARLS is a premium straight-thread hose fitting engineered for high-performance automotive cooling and fuel system applications. Designed for mechanics and enthusiasts who demand reliability in modified engines and race builds, this fitting delivers the secure connections necessary in demanding underhood environments where vibration and heat stress can compromise inferior components. Whether you're upgrading a street performance engine or assembling a competition vehicle, the Auto-Mate provides the corrosion resistance and durability required for year-round reliability.

Constructed with EARLS' proprietary Ano-Tuff anodized aluminum finish, this fitting resists oxidation, galvanic corrosion, and chemical attack from modern coolants and synthetic fuels that can degrade standard brass or steel fittings over time. The straight-thread design (#6 SAE) ensures precise hose port alignment without the need for adapter configurations, simplifying installation while maintaining a clean engine bay aesthetic. The compact 0.95 x 0.75 x 2.5 inch profile allows flexible routing in tight intake and radiator environments, while the minimal 0.02 lb weight contributes negligibly to overall vehicle mass—critical in weight-conscious builds.

This fitting is ideal for custom coolant loops, fuel line upgrades, and forced-induction setups where OEM hose routing proves inadequate. Professional engine builders and shade-tree mechanics alike rely on EARLS fittings to eliminate mid-race failures and weeping connections that plague budget alternatives. Installation requires standard SAE hose clamps and compatible -6 AN hoses; verify your system's thread orientation and hose sizing before ordering to ensure proper sealing and leak-free operation under boost or sustained high-rpm conditions.
