The Russell Performance 670501 adapter fitting connects a -4 AN hose end to a 10mm x 1.0 metric-threaded component. Designed for automotive fluid systems, this flare-to-metric adapter supports connections to components such as oil pumps, fuel pumps, fuel filters, and other compatible applications. Its Endura finish provides a clean, bright appearance that complements professional hose installations.
Constructed from precision-machined 6061-T6 aluminum, this Russell adapter is engineered for reliable performance and a positive seal at maximum operating pressures. The lightweight design helps support efficient installation while maintaining the strength required for demanding automotive plumbing systems. Verify the AN size, metric thread, flare type, hose series, and sealing style before assembly to ensure compatibility.
Install the adapter and connected hose ends according to the manufacturer’s instructions. Inspect all sealing surfaces for damage, route lines safely away from heat and moving components, and pressure-check the completed system for leaks before operation. This fitting is available while supplies last. Prop 65 warning applies.
