For “DRY” pneumatic conveying of solids where heavy-duty abrasive are present. Special formulated HMV PVC compound provides subzero flexibility and the exposed PVC helix allows for excellent abrasion resistance and easy drag. The smooth polyurethane lining eliminates material build up, and is formulated with static dissipating compounds. Tube: Polyurethane Lined (static dissipating) Reinforcement: High density rigid PVC helix Cover: Black HMV PVC Temperature range: -40° F to +150° F
