The POWERTEC Flexible PVC Hoses are heavy duty, super flexible, chemical resistant, and abrasive and tear proof! Temperature resistant up to 176F. They are made of soft, high grade PVC with reinforced spring steel in the walls for greater durability. This super strong hose will not collapse under pressure from your dust collector and is ideal for sawdust, powder and ventilation. Flexible construction allows you to position the hose exactly where you want, and clear material allows you to see inside the hose!
