Multilayer Composite Hose
By tests, common fuel evaporation of monolayer hose is about 27 times as much as the multilayer hose, and its CE10 fuel evaporation is 850 times as much as the multilayer hose. The multilayer nylon composite hose developed based on the environmental protection requirement is featured by low permeability, anti-aging, safety, environmental protection, low cost, convenient assembly, stable dimension, and application to fuel-alcohol mixture, and is widely applied to auto fuel systems now.
