As a result of using this Industrial and Scientific hydraulic coupling, I found that it was extremely flimsy and couldnt withstand the pressure of the hoses. During use, the coupling failed and caused a leak, which could have resulted in serious injury or damage. The only pro I can think of is that it was easy to attach to the hose, but that's irrelevant when it can't do its job properly. Overall i would not recommend this product to anyone in need of a reliable hose coupling..
