Vibrant Performance - 2762 - Reducer Coupler, 1.50 in. I.D. x 1.75 in. I.D. x 3.00 in. long - Black

This Vibrant Performance reducer coupler is built tough with hand-wrapped aramid reinforcement and a robust 4-ply construction that handles extreme temperatures and pressure spikes without flinching. Whether you're running an aggressive cooling system upgrade or connecting different diameter hoses in your custom setup, this coupler won't swell, burst, or let you down—it's engineered to exceed SAE J20 specifications and shrug off UV and ozone exposure. The 1.50 to 1.75 inch ID transition spans 3 inches long, giving you the flexibility to step down or up your coolant line diameter while maintaining a reliable seal from -65°F to 350°F. If you're building a serious cooling system or turbo cooling circuit and need components that match your performance ambitions, this is the quality you can trust under the hood.
