Snap-tite Hose HFX is a nitrile thru-the-weave, rubber covered fire hose that utilizes both polyester and nylon yarn in the reinforcing jacket. Under pressure, the polyester keeps the hose from “snaking” where the nylon allows for controlled dilation, reducing friction loss and generating higher flow rates. Our special rubber compound provides a tough cover that resists heat, abrasion, snags, and hot embers. HFX’s unique extruded thru-the-weave construction provides a flexible, easy to maneuver hose that is easy to pack. The interlocking matrix also means no adhesives are used and there is a permanent bond to all the warp and filler yarns.
