Rubber-Cal "Air Ventilator Heavy-Duty" Ventilation Hose - 8 in. ID x 25 ft.

The "Air Ventilator Heavy-Duty" ventilation flex hose is a highly durable air ventilation duct that is well suited to industrial air movement applications. This flexible ventilation duct is made with a thick PVC vinyl coated polyester fabric that is reinforced with a spring steel wire helix and external wear-strip. The spring steel wire helix in each of these heavy-duty ventilation ducts gives them a stronger form and a degree of flexibility. It can help prevent the air hose from being crushed or deformed. The external wear-strip on the outside of this durable air ventilation hose is meant to provide an added layer of protection against physical abrasion. The biggest differentiator that separates these air ventilation ducts from others is its heavier PVC fabric material. Although the spring wire helix allows for easier compressibility and transport, this ventilation ducting is heavier than its standard counterparts. It can also handle high and low temperature situations, with a working range between -20° F...
