Vibrant Performance Aramid Reinforced Charge Air Cooler Transition Hose Coupler 4.00in x 3.00in ID - Universal

Vibrant Performance Aramid Reinforced Charge Air Cooler Hose Couplers connect 4.00 inch to 3.00 inch piping in custom turbo and supercharger intercooler systems on performance vehicles. These 3 inch long transition couplers compensate for minor misalignment and isolate vibration for smoother airflow. Stainless steel rings maintain shape under boost pressures while aramid layers support temperatures from -75 Degrees F to 392 Degrees F.

Key Features

  • Aramid Reinforcement: Multi-layer high temperature resistant fabric between silicone enables reliable operation from -75 Degrees F to 392 Degrees F (-60 Degrees C to 200 Degrees C)
  • Stainless Steel Rings: Embedded rings resist expansion and ballooning during high pressure boost conditions
  • Vibration Isolation: Flexible design absorbs engine vibration and corrects minor piping misalignment for leak-free connections
  • Transition Sizing: Precise 4.00in x 3.00in inner diameter suits common charge air cooler piping reductions in intake systems
  • Versatile Service: Rated for hot side cold side air water and coolant applications in performance turbo setups

Product Notes

  • Designed for charge air cooler plumbing use with appropriate hose clamps for secure fit
  • Clean with mild soap and water avoid harsh chemicals to maintain silicone integrity
  • Packaged in protective poly bag ships ready for immediate installation

Installation Notes

  • Professional installation recommended.
