Charge Air Cooler Hoses

When your charge air cooler system needs dependable hose connections, American Radiator offers premium silicone hoses designed specifically for CAC (intercooler) applications. These charge air cooler silicone hoses replace worn rubber lines with far stronger, heat-resistant material that better resists collapse, cracking, and pressure fatigue—especially under boost.

Built to handle extreme temperatures and pressure swings, our silicone hoses maintain airflow integrity, minimize turbo lag, and preserve charge air efficiency. Available in multiple diameters and wall thicknesses, these hoses serve heavy-duty platforms including Freightliner, Kenworth, Peterbilt, Volvo, and International trucks. Every hose is engineered for compatibility with existing clamps, bends, and couplings, making retrofit or replacement seamless.

Because degraded hoses can choke cooling efficiency and reduce engine power, we stock a broad inventory and support your selection with fitment advice and fast delivery. Whether your CAC line needs a straight coupler, elbow section, or custom piece, our silicone hose options outlast standard rubber parts while stabilizing airflow under load.

Trust American Radiator for charge air cooler silicone hoses that deliver consistent performance, extended life, and reliable boost delivery—helping your engine run cooler, stronger, and more responsively across every mile.

FAQ'S

What is a charge air cooler hose?
A charge air cooler hose (intercooler hose) carries compressed intake air from the turbocharger to the intercooler and then onward to the intake manifold. It must withstand high pressure, heat, and airflow without collapsing or leaking.

How do I pick the correct size and type of intercooler hose?
You should match inner diameter (ID), wall thickness, bend radius, length, and end connectors. Use OEM part numbers or measure your existing hose segments to ensure correct fitment.

What materials are used in charge air cooler hoses?
Heavy-duty charge air cooler hoses are typically made from reinforced silicone or specialized synthetic elastomers with textile or braided internal layers to resist pressure, heat cycling, and ozone degradation.

Can charge air cooler hoses collapse under boost?
Yes — under high boost pressure or vacuum conditions, improper or weak hoses can collapse or deform. That’s why reinforced hoses with thick walls and supported construction are necessary to maintain consistent airflow.

When should I inspect or replace my intercooler hoses?
Inspect every service interval (e.g. during coolant or belt maintenance). Look for bulges, cracks, soft sections, oil contamination, or hardening. Replace hoses showing signs of damage before they fail under load.
