• Silicone hoses have a higher water permeation rate than standard EPDM rubber, so regular coolant level checks are recommended for daily driving

Construction & Design

The HPS radiator hoses are crafted from reinforced silicone, a material known for its superior heat resistance and flexibility compared to traditional rubber hoses. This construction allows the hoses to maintain structural integrity and resist cracking, swelling, or collapsing even under prolonged exposure to high engine and coolant temperatures. The hoses are precision molded to replicate the exact bends and curves of the OEM hoses, ensuring a seamless fit without modifications.

Included stainless steel clamps are embossed and non-perforated, designed to provide a secure seal without cutting into the silicone, which enhances longevity and prevents leaks. This combination of materials and design results in a robust cooling hose system that outperforms standard rubber hoses in both durability and reliability.
