Series SW431 is a low pressure suction and discharge hose designed to handle dry abrasive materials such as flour, grains, granules, pellets and powders; non-fatty and non-oily foods, liquids, sanitary products and potable water in a variety of transfer applications. The hose is manufactured using polished stainless steel mandrels for an ultra-smooth, bacteria-free tube that will not impart taste or odor, and is resistant to abrasion. The lightweight construction incorporates a thick tube for abrasion resistance. The dual wire helix provides full suction capability, kink resistance and a path to conduct a static electrical charge to ground. The natural rubber cover is resistant to abrasion, mild chemicals and ozone.
