#3 to 10mm x 1.0 Male Fitting Endura

The Russell #3 to 10mm x 1.0 Male Fitting Endura is a precision hydraulic adapter designed for custom fuel, coolant, and brake line systems in high-performance and modified vehicles. This fitting serves as a critical connection point in fuel injection systems, turbo cooling circuits, and pressurized fluid applications where reliable, leak-free performance is essential. Whether you're building a custom engine bay setup or installing aftermarket cooling lines, this male fitting provides the secure transition between incompatible line sizes that keeps your modifications running safely.

Russell fittings are engineered with precision hose-end design that accommodates #3 (3/16-inch) hose diameter on the inlet side and transitions smoothly to a 10mm x 1.0 metric thread male connection on the outlet. The construction is designed to resist fuel degradation, coolant corrosion, and thermal cycling common in modified engine compartments. The 1.0 metric pitch ensures compatibility with standard metric hydraulic systems found in modern performance builds.

This fitting excels in turbo installations, EFI fuel system upgrades, auxiliary cooling loops, and custom brake line routing where precision sizing prevents connection issues and system failures. Mechanics and enthusiasts will appreciate the reliability and performance this fitting brings to their projects, ensuring that their modifications operate safely and efficiently.
