Vibrant 16610 -4AN to M16x1.5 Straight Adapter Fitting

The Vibrant Performance 16610 is a precision-machined straight adapter fitting designed to connect -4AN hose ends to metric M16x1.5 threaded ports. This adapter provides a reliable, leak-free transition between AN (Army-Navy) plumbing systems commonly used in performance automotive applications and metric threaded components found in many European and Asian vehicles.

Key Features:

• -4AN female thread on one end for standard AN hose fittings
• M16mm x 1.5 pitch male metric thread on opposite end
• Straight inline configuration for direct port connections
• Precision CNC-machined construction for accurate thread fit
• Ideal for fuel systems, oil lines, coolant systems, and brake applications
• Compatible with Vibrant and other quality AN hose ends

This adapter is essential for custom plumbing installations where you need to interface between AN braided hose assemblies and metric-threaded ports on turbochargers, fuel rails, oil pans, transmission coolers, and other performance components. The straight design minimizes space requirements and maintains clean routing in tight engine compartments.
