Seal your turbocharger and charge-air-cooler plumbing with the Flexfab 4075-0002 Heavy-Wall CAC Hose — a blue silicone connector built for the heat and boost pressure of diesel charge-air systems. Engineered to withstand hostile engine environments, it resists the cracking and blow-off that plague lesser connectors.

Why this Flexfab charge air connector

• 4-ply heavy-duty silicone-coated meta-aramid construction — high pressure and heat resistance for hot or cold side of the CAC system.
• Rated to +500°F (from −65°F) — handles post-turbo intake heat without hardening or failing.
• Heavy-duty stainless steel pressure retention rings, clamp-saddle design, chamfered id — engineered for a secure, blow-off-resistant connection.
• 4.50" ID × 6.00" overall length — sized to fit standard charge-air piping.
• Oil-splash, ozone, and UV resistant — long service life under the hood.

Ideal for diesel truck engines delivering pressurized intake air to the intercooler and intake manifold. Pair with appropriate T-bolt clamps for a secure seal.
