Wear-resistant  Suction and Discharge Rubber Hose                                       
Construction:                                    
TUBE: Black wear-resistant  synthetic rubber                                    COVER: Black  synthetic wear-resistant  rubber (wrapped finish)
REINFORCEMENT:Multi layers high tensile  plied synthetic textile with wire helix
Application:                                    
Used to suck  solid materials or grain materials  such as mineral sand ,bits  of coal and cereal ( rice , wheat, corm ) ect .                                                        Characteristics:                                    
Good  flexibility and  durability . the inside layer is abrasion-resistance and the outside layer is anti-aging and wear-resistance.  The hose can bear both positive and negative pressure.  the hose works well even under the pressure of -80kpa at the vacuum. The burst of the hose is three times or higher than the working pressure.
