The HPS Silicone Radiator Hose Kit provides a high-performance solution for replacing or upgrading your vehicle’s stock rubber cooling hoses. Constructed from premium-grade 3-ply reinforced silicone, these hoses are designed to endure extreme heat—up to 350°F—while maintaining strength, flexibility, and pressure integrity under demanding driving conditions. Each hose is precision-formed with the correct bends and curves to ensure perfect fitment and smooth coolant flow. The included 100% stainless steel non-perforated embossed clamps deliver a tight seal without damaging the hose surface, guaranteeing long-term reliability. This kit helps prevent coolant leaks, hose cracking, or collapsing—issues that commonly occur in worn or aged OEM hoses. Engineered with a race-proven design, the HPS Silicone Radiator Hose Kit offers exceptional durability and performance for both high-performance and daily-use applications. Note: Silicone hoses have a higher water permeation rate than standard EPDM rubber hoses, so regular coolant level checks are recommended for vehicles used daily.
