Suction & Discharge Composite Hose Transfers Fuel Oil

Suction & discharge composite hose is applied to the suction and discharge of fuel oil products such as gasoline, diesel, liquefied petroleum gas (LPG), etc. It has good antistatic properties and can withstand high pressure, abrasion and high temperature. In the suction or discharge operation, the inner coil of the hose supports hose wall to prevent hose from collapsing under the action of suction. The outer coil gives the hose resistance to pressure, protecting the hose from external wear and tear.
