The Mishimoto DuraCore 3-Inch Straight Silicone Intercooler Coupler, part number MMDCC-30SBK, is engineered to provide a secure connection between compatible intercooler, intake, and cooling-system piping. Designed for custom fabrication and performance applications, this straight coupler helps create a tight, leak-resistant seal while accommodating the heat and pressure demands of high-boost systems. Its 3-inch connection size is suited for piping layouts that require a reliable, direct joining point without an angle or transition.
DuraCore technology forms the innermost layer of this Mishimoto silicone coupler, providing improved resistance to heat, pressure, fuel, and oil compared with conventional silicone hose materials. The coupler is constructed with five silicone layers and heat-resistant embedded reinforcement fibers to help prevent leaks, blowouts, and premature wear. This durable construction supports dependable performance in demanding engine-bay environments while maintaining flexibility for easier installation and alignment.
The MMDCC-30SBK is designed for use with properly sized piping and compatible clamps, helping simplify custom intercooler and charge-pipe installations. Its straight configuration is practical for connecting tubing sections with matching diameters, making it a versatile component for turbocharged trucks, cars, and other performance builds. Mishimoto offers additional DuraCore configurations, including straight hump, transition, 45-degree, and 90-degree couplers, to support more complex routing requirements. Professional installation and appropriate clamp selection are recommended for the best seal and long-term reliability.
