Review on Interstate Pneumatics F7327-50 Brass Fitting Hose Ferrule 5/8 inch Inner Diameter x 1.0 inch Pack of 50 by Alejandro Dabney

I bought these because they need to work with 3/8 inch ID air hoses. These are .625" ID options. They WILL NOT FIT as the ID of the tip is smaller than the OD of Goodyear's 3/8" ID rubber air hose which is .650". Sent this box back and already ordered .750 inch. Product description so that the buyer can determine what size is needed. I'm not necessarily blaming the product here, just trying to get Revain to fix the product description page. Oh, and DO NOT buy these if you don't have or don't want to buy a crimping tool. They are useless without crimping tools. So what can you do to take away? If you're trying to make 3/8" ID Goodyear tubing or similar .65" OD tubing, buy the .750" variety of these tubing. Tips. I have a few synthetic tubing that will do this could, but I will not make them in custom lengths.
