Note: Parker Series SW431 has been obsoleted and will no longer be available for purchase. Parker does not currently have a recommendation for a replacement hose.

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.
