  • Hot-side location – Installs between the turbocharger outlet and the charge-air cooler, carrying compressed air up to 500 °F before intercooling.
  • Aramid reinforcement – 4-ply meta-aramid fabric resists heat, ozone, and oil splash while maintaining flexibility under engine vibration and frame twist.
  • Dual “hump” profile – The molded convolute absorbs engine movement and mis-alignment, preventing clamp walk and bead roll failure.
  • Stainless retention rings maintain hose geometry under boost, preventing ballooning and reducing clamp-torque loss during thermal cycles.
  • Industry compliance – Built to SAE J20 and TMC RP303B, ensuring interchangeability with OE hoses on Freightliner, Volvo, PACCAR, Navistar, and other Class-8 platforms.

Heavy-duty 4 in × 6 in hot-side charge-air cooler hose designed to connect the turbo outlet to the intercooler on Class-8 diesel trucks. The 4-ply meta-aramid–reinforced silicone construction withstands continuous 500 °F inlet-air temperatures and 50 psi boost while absorbing vibration through its dual-hump profile. Oxide-red coloring clearly identifies the hose for high-temperature service, simplifying maintenance and reducing installation errors.
