Bulldog Hi-Vol is a tough large diameter hose with the ability to deliver more water at a lower cost. But it doesn't stop there. It is lightweight, compact and durable with a high resistance to oils, chemicals, ozone and heat. Its tough, high tensile cover and lining, permanently interlocked with the synthetic reinforcement, provide greater abrasion resistance while being snag-proof, kink resistant, and immune to mildew or rot. U.L. labeling is available on 4" (100 mm) and 5" (125 mm) only. The standard colors for Hi-Vol are yellow or red.
