Williams Double-5 Industrial Fire Hose

Print Page

Williams Double-5 Industrial Hose is a unique lightweight 7¼” (184mm) large diameter hose woven with 100% filament polyester for superior durability and pressure performance.  It is capable of significant water flow at higher pressures, yet with minimal friction loss of less than 3 psi per 100 feet (0.21 bars/30.5 m) @ 1500 GPM. It can flow twice as much volume as a 5” (127 mm) hose, hence the name “Double 5”.  It is specifically designed to combat oil refinery and large storage tank fires and features a double jacket construction with ozone and aging resistant Thermal Polyurethane lining. The outside jacket is treated with beige (tan) ENCAP elastomer, which completely encapsulates the jacket fibers and not merely surface coat the jacket, to provide water repellency, abrasion, oil and chemical resistance.
