Mishimoto DuraCore Straight Hump Silicone Coupler Black

The Mishimoto DuraCore Straight Hump Silicone Coupler (also sold as a silicone intercooler boot or hose coupler) joins intercooler piping, charge pipes, and intake or cooling system tubing. It is built for custom fabrication and high-boost applications. The hump design adds flexibility, so the coupler absorbs movement and vibration without compromising the seal.

Key Features:

• DuraCore synthetic inner layer: resists heat, pressure, fuel, and oil better than standard silicone alone. This helps prevent leaks and blowouts under high boost.
• Multi-layer construction: five layers of silicone with heat-resistant embedded fibers give the coupler structural strength.
• Hump-style design: absorbs engine and piping movement and vibration while keeping the connection leak-resistant.
• Reinforcing rings (where applicable): add structural integrity so the connection stays secure under pressure.
• Part of a full DuraCore range: the line also includes straight, transition, 45-degree, and 90-degree configurations, so you can complete a piping kit with matching components.
• Easy installation: the manufacturer rates installation difficulty as easy.
• Mishimoto Lifetime Warranty.

DuraCore couplers are designed to be the strongest link in a custom intercooler piping setup. They give builders a durable, leak-resistant connection that holds up to heat, boost pressure, and vibration.
