The Mishimoto DuraCore 4-Inch Straight Hump Silicone Intercooler Coupler, part number MMDCC-40HBK, is designed to create a secure connection between intercooler piping and other charge-air system components. Its straight hump configuration provides added flexibility to accommodate engine movement, vibration, and minor alignment changes while maintaining a dependable, leak-resistant seal. This coupler is well suited for custom turbocharger, intercooler, intake, and cooling system fabrication projects.
Mishimoto DuraCore technology uses a specialized inner silicone layer engineered to resist heat, pressure, fuel, and oil better than standard silicone couplers. The coupler is manufactured with five layers of silicone and embedded heat-resistant reinforcement fibers to support reliable performance in demanding high-boost applications. Reinforcing rings help maintain structural integrity and connection security, while the flexible hump design absorbs movement without compromising the seal.
The 4-inch size is ideal for compatible intercooler and charge piping, making the MMDCC-40HBK a practical choice for custom layouts and performance-oriented builds. Mishimoto offers straight, straight hump, transition, 45-degree, and 90-degree configurations to help match a wide range of routing requirements. Pair this coupler with properly sized clamps for a secure installation and dependable long-term service. The Mishimoto DuraCore MMDCC-40HBK delivers the flexibility, durability, and pressure resistance needed to help prevent leaks and premature boot failure.
