Key Hose – Pro-Flow Lightweight Rubber Covered Hose

Please call 1-800-544-6038 for Pricing

A lightweight, heat resistant, rubber covered hose that delivers superior flow every time, everywhere. 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 ribbed rubber outer cover offers increased resistance to impact, punctures and abrasion. Reliable, maintenance-free and requires no drying, makes this the ideal hose for dewatering, industrial fire fighting, large diameter supply hose and wash down on construction sites. NFPA compliant and UL Listed*.
