A lightweight, heat-resistant, large diameter supply hose that delivers superior flow during fireground operations.

Ozone and chemical resistant, the nitrile/PVC through-the-weave design allows the hose to expand under pressure — decreasing friction loss and increasing water flow.

The thin rib rubber outer cover offers increased resistance to impact, punctures, and abrasion. Reliable, maintenance-free, and no drying required, make this the ideal supply hose for municipal and industrial fire departments. NFPA compliant and UL Listed*.
