I purchased three of these hoses, they are even more industrial than I anticipated! I was especially pleased with the connections; each fitting had two permanent clamps (not just one on each end as was pictured.) The male fitting is brass, and the female fitting is heavy steel - the hose is quite heavy. I connected all three of mine together for 150 feet capability - but actually only needed 50 foot and instead "stepped down" the connections to use my alternate garden hoses for ease of mobility. My family joked about my becoming a "fireman" with these hoses!
