The picture below will describe this better than I can, but our 100 ft hose just blew apart at the faucet connection and it seems some piece that would go on the inside (maybe a rubber or plastic gasket?) fell out or inside the hose. I figured this should be an easy part to replace but have no idea what part/size I should be looking for. Don’t want to throw out a relatively new 100’ hose just for one small part!
See Polypipe Wrangler's answer below... And here's a picture that shows what he's talking about. I was able to use a wire to pull this out and will try to find a way to secure it better so it doesn't blow out again.
