Custom EPDM coolant hose designed for battery thermal management systems in electric vehicles, electric construction machinery, electric boats, and energy storage applications. Resistant to glycol coolant, ozone, aging, and long-term heat exposure.

Engineered for High-Concentration Ozone and Advanced Oxidation Systems
Standard rubber and lower-tier elastomers fail rapidly under constant ozone exposure, leading to brittle walls, cracking, and dangerous gas leaks. PASSIONHOSE manufactures top-tier Pure Silicone Tubing specifically engineered to handle aggressive oxidizing environments inside modern ozone generation and water treatment systems.

Explore the premium structural design of our medical-grade braided silicone hoses in this close-up video. Specifically engineered for high-purity medical and pharmaceutical fluid transfers, this hose combines a platinum-cured silicone inner liner with a high-tensile braided fiber core. It delivers advanced burst pressure protection while remaining highly flexible, non-toxic, and fully compliant with global medical-grade regulatory standards.

SAE J30R14 Low Permeation Fuel Hose is engineered for modern fuel systems. It provides excellent resistance to gasoline, diesel, and ethanol-blended fuels (E10/E15/E85), significantly reduces fuel vapor permeation, and delivers reliable performance for fuel and vapor transfer applications while supporting modern emission standards.

This reinforced low permeation hose is designed for critical automotive emission and vapor control applications where sealing performance, pressure stability, and environmental resistance are essential.

It features a multi-layer construction combining a reifnorcement inner liner for ultra-low fuel vapor permeability, an EPDM intermediate layer for flexibility and thermal stability, an aramid fiber reinforcement layer for pressure resistance, and an EPDM outer cover for weather and ozone protection.

This structure ensures stable performance in EVAP systems, vacuum lines, and low-pressure fuel vapor transfer applications under demanding engine bay conditions.
