Product Description

The Mishimoto MMDCC-35HBK is a 3.5in straight hump DuraCore silicone coupler designed for custom intercooler and charge piping fabrication. When building a piping kit from scratch, every connector needs to reliably hold up under boost, and this coupler is engineered to be the strongest link in that system.

DuraCore technology forms the synthetic innermost layer of the boot, delivering meaningfully better resistance to heat, pressure, fuel, and oil than standard silicone construction. Combined with five layers of silicone reinforced with heat-resistant fibers, this coupler is built for long-term durability, minimizing the risk of leaks or blowouts under sustained boost pressure.

The straight hump design provides a slight bulge in the middle of the coupler, which helps accommodate minor pipe misalignment while still maintaining a secure, leak-resistant seal - a useful feature for custom fabrication where perfect pipe alignment isn't always achievable. As a universal-fit component, the MMDCC-35HBK isn't tied to a specific vehicle - it fits any 3.5in diameter piping project. It's backed by Mishimoto's lifetime warranty, and matching clamps are available separately to complete the installation.
