3/8" Male NPT Rigid End X 3/8" Male NPT Swivel End 310°F Max Temperature 350 Max PSI American Pressure's Black Hose is available in various lengths to accommodate all cleaning scenarios. This black hose now features a thicker inner wall to prevent gashes and ruptures and is great for any pressure washing application. Kobrajet is manufactured out of high quality components and assembled in the U.S using 'Bite the Wire' technology when installing the 3/8" rigid and swivel fittings. This technique guarantees that your hose ends will stay in place and will not rupture or blow off during pressure spikes. These advanced fittings also have a longer life with superior resistance to corrosion due to the salt spray test which yielded results of 125 hours before corrosion was detected; nearly twice the industry standard, meaning your hose will last longer, especially in abusive environments. Available in 50 and 100 foot lengths.
