On my normal RV hoses, I coil the hoses into a circle and screw the two ends together to keep and insects from finding their way into the hoses, but with my heated / winter fresh water line, I don't want to put that much stress on the hose, so I use these. They work great! I put the appropriate one on each end of the hose when I'm not using it and it seals it perfectly. They are easy to use. They should come with the hose. Would buy again.
