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.
