I am setting up my first big-ish (60 gal) air compressor and have some questions about fittings and hoses. I have watched just about every Eastwood video and Kevin says to use 3/8 inch fittings for good flow. I was shopping for a hose reel and trying to apply the same logic. When comparing hoses, I have noticed a big difference in the internal size of the fittings on the end of the hoses. They are all 3/8 inch connections, but some of them are very restricted where the hose is crimped onto the fitting. Does this make a difference? Thanks.
