Vibrant 4 Ply Reducer Coupling .75in x .50in x 4in Long - Black - Universal Fit
Vibrant Performance aramid reinforced silicone transition hose couplers connect differing pipe sizes in custom air intake turbocharger piping and intercooler plumbing. This 4-inch long reducer steps down from 0.75-inch to 0.50-inch inner diameter for precise flow transitions in performance builds. Built with high-temperature silicone layers and aramid fabric reinforcement it withstands -75°F to 392°F for reliable water coolant and air service.
Key Features
- Aramid Reinforcement: 4-ply fabric between silicone layers boosts burst strength to 100 PSI at 70°F and resists kinking under pressure
- Wide Temperature Range: Operates from -75°F to 392°F (-60°C to 200°C) to handle extreme engine bay heat and cold starts
- Precise Dimensions: 0.75in to 0.50in inner diameter transition over 4in length with 0.160in wall thickness for secure mandrel-bent pipe connections
- Flexible Construction: Premium silicone allows 360-degree rotation and easy shaping during installation without cracking
- Black Silicone Finish: Heat-resistant color maintains appearance under hood and provides clean professional look
