Poly-Cord ring-spun polyester warp yarns are combined with filament polyester filler yarns. Available either plain / uncoated “natural” white, or with our optional Ultra-Shield high performance polymeric coating applied to seal each and every fiber in the bundle, further improving the abrasion resistance, reducing moisture and chemical absorption, and providing vivid color-coded identification. The 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 improving nozzle performance. The Dura-Bond vulcanized adhesion system, which creates both a mechanical and chemical bond between the EPDM lining and the jacket, reduces the probability of delamination as is experienced with competitive adhesive bonded rubber lined constructions. The result is a very strong, flexible, and “Tuff” hose, with good heat and chemical resistance. Both the hose and couplings are made in the USA, performance shall meet and exceed NFPA 1961, FM and UL standards.
