The BLU SHIELD 3/8 in. x 50 in. Kevlar braided rubber pressure washer hoses are unique and one of its kind. These hoses are braided with Aramid fibers, commonly known as Kevlar, which makes them 35% lighter than other pressure washing hose while making it heavy duty. Aramid fibers are well-known for durability and extraordinary tensile strength and are up to 10 times stronger than steel fibers of equal diameter. These 100% rubber hoses are extreme weather resistant hoses that can also handles hot water up to 250°F while remaining flexible in cold weather temperatures up to -20°F. Included four finger grip bend restrictors reduces the bending stress near the coupling and increase the working efficiency by adding better control. These hoses have a 4,100 PSI working pressure and a 16,400 PSI safety burst pressure (4:1).
