Insulated Blo-N-Vent Duct Hose with Wear Strip for Air

Very Flexible
Compatible Clamps: Worm-Drive and Quick-Release Clamps
Color: Yellow; Wear Strip is Black
Temperature Range: -40° to 250° F

A layer of fiberglass insulation helps maintain the temperature inside the hose. Use for heating and cooling applications in outdoor environments. Hose has a wear strip that protects against damage caused by dragging. The liner meets UL 94 V-0 for flame retardance. The ends are cuffed for easy attachment to duct hose connectors.
