Kuriyama's Tigerflex® GT™ Series Ducting/Material Handling Hose is constructed of a PVC tube with a rigid PVC helix. The rigid helix design protects the hose tube from cover wear and allows the hose to slide easily over rough surfaces. The antimicrobial tube inhibits the growth of bacteria, fungi, mold, and yeast. General applications include cable protection, drain lines, dust collection, light duty material handling and ducting, ventilation, and fume removal.
