Heavy-duty construction that complies with all applicable FDA requirements. Clear polyurethane and blue PVC helix construction allows for visual confirmation of material flow. Smooth bore construction eliminates material build-up. Yarn reinforced for discharge applications. Heavy corrugation provides extra flexibility. Embedded wire prevents static electricity build-up. Grounding wire must be properly terminated at both ends in order to dissipate static electricity. Below specification at 70°F. Tube and Cover: Clear, flexible Polyurethane with blue PVC rigid helix. Reinforcement: Blue, Tough vinyl helix, synethetic yarn embedded copper wire for grounding. Safety Factor: 3:1. Temperature: -40°F to +150°F
