G722 Sandblast is designed to conduct sand, shot, glass beads, and other abrasives at high velocity. The tube is static conductive to prevent dangerous shocks and the outside diameter is designed to accept over-the-cover sandblast couplings. The life of a sandblast is greatly affected by velocity of flow and amount of hose bending. Typically, hoses will wear out on the outside radius of a curved hose, especially near the operator where it is continuously flexed. Selection of the correct nozzle size is important to prevent premature wear. Please see the chart below. Sandblast whip hoses are designed with a reduced outside diameter for extra flexibility to reduce operator fatigue. However, the tighter bends that occur with the smaller outside diameters will reduce hose life.
