WILLIAMS FIRE & HAZARD CONTROL® (WILLIAMS) Taiga large diameter hoses are heavy-duty, industrial grade hoses for extreme firefighting. Japanese for 'big river,' Taiga hoses deliver maximum flow in hazardous situations requiring high water volume and pressure.
The WILLIAMS team drew upon their extensive industrial firefighting and hazard mitigation experience when developing specifications for Taiga hoses, which are manufactured by the Niedner company exclusively for the WILLIAMS product line.
Taiga 1200 and Taiga 600 hoses are constructed with a circular woven double-jacket of 100% virgin polyester. The polymer encapsulated treatment on the outer jacket improves abrasion resistance and durability, reduces water absorption, and enhances chemical resistance. The inner lining of extruded thermoplastic polyurethane (TPU) enhances flexibility, compactness, and resistance to ozone and aging.
The Taiga 1200 hose is rated as a Super Large Diameter Hose (SLDH) and is equipped with proprietary four-lug Storz couplings. These couplings are easy to attach and separate, and tolerant of dirt and other small particles in the field. The Taiga 600 hose is rated as a Large Diameter Hose (LDH) and is equipped with standard Storz couplings.
Both hoses are rated with a best-in-class 200 psi (13.8 bar) service test pressure, and a minimum of 600 psi (41.3 bar) pressure before bursting. These hoses meet or exceed NFPA 1961 specifications.
Taiga hoses are available in various lengths up to 500 ft (152 m). A variety of color options are available, including beige, tan, yellow, purple, blue, orange, red, green, and white.
