Fire-Resistant High-Pressure Water Hose with Male and Female Threaded Fittings

Temperature Range: -20° to 200° F
Material: Blended Rubber
Color: Yellow
Female Fitting Swivels Until Tightened

Because the cover on this hose meets MSHA (Mine Safety and Health Administration) standards for flame resistance, it is commonly used to control dust in mines. Hose is also abrasion and ozone resistant. Fittings are also known as ground-joint couplings. Fittings that swivel until tightened are easy to install.
