Construction & Design

Mishimoto’s silicone hoses are engineered using a multi-layer construction that combines premium silicone rubber with four layers of woven heat-resistant fibers. This design not only provides exceptional resistance to heat and pressure but also prevents hose deformation and cracking over time. The silicone material remains flexible in cold temperatures and resists swelling or softening in high heat, ensuring consistent performance in all climates.
