Hose is constructed with Ester polyurethane (TPU) tube with rigid PVC helix and grounding wire. Durable lightweight polyurethane tube is designed for dry applications where abrasion is a factor. Grounding wire helps prevent the build-up of static electricity for added safety and to help keep material flowing smoothly. Use of “Cold-Flex” materials provides flexibility in sub-zero temperatures. Exposed rigid helix allows hose to slide easily over rough surfaces. General applications include use in food grade blower and ducting systems, dust collection and pharmaceutical product transfer.
