Exclusive DURA-CORD® advanced, air-textured Nylon 6-6 continuous filament warp yarns, resulting in superior toughness, abrasion resistance, cut resistance, tear strength and heat resistance when compared to competitive nylon, spun polyester, or filament polyester warp constructions. DURA- CORD® is the registered trademark for NAFH. Fire hose sold under this brand is specifically manufactured by NAFH. Unique Ultra-Shield high performance polymeric coating seals each and every fiber in the bundle, further improving the abrasion resistance, reducing moisture and chemical absorption, and providing vivid color-coded identification. EPDM rubber lining is unaffected by Ozone deterioration, and is one component in the Friction Fighter System, creating an extremely smooth waterway surface, thereby reducing friction loss and significantly improving nozzle performance. Both the hose and couplings are made in the USA, performance shall meet and exceed NFPA 1961 standards.
