Blast-Flex Sand Blast hose has been engineered to handle the cleaning, cutting or finishing store, glass and metal surfaces. This hose will conduct sand, steel, shot or other sharp abrasives at high velocity. Blast-Flex features a 1/4″ thick. SBR/NR tube that resists abrasion in sandblast service. The state-conducting properties of this hose prevent the buildup of electrical charges. The black SBR/EPOM cover resists abrasions, cuts and snags. The reinforcement of four spiral plies of heavy fabric resists collapsing and kinking when the hose is bent. The larger sizes of Blast-Flex are reinforced with heavier weight fabric for added strength.
