Fuel Cell Coolant Silicone Hose For Fuel Cell Vehicles (FCVs)
Fuel cell hose lined with food grade silicone tube is built to delivering cooling water, oxygen gases, hydrogen in fuel cell powered vehicle applications. Result from the high cleaness requirement by the fuel cell, in addition to use food grade silicone liner, Goodyou cleans fuel cell hose using deionized water in dust-proof workshop to better control the particles.
Fuel cell hose is overlaid with plies of silicone, reinforced with aramid cloth. The number of plies varying depending on working pressure, bore size and required wall thickness. We have tooling making ability in house, are available for fast action. We provide perfect personally tailored service to meet customers' demand.
