Great value to start with. When properly installed, it never leaks. I use a 3/8 stun socket and twist counterclockwise to line up the female part, which works for me every time. Apply a small amount of dielectric grease or other lubricant to the male end and slide the fittings over each other without being tight. If you use a cutting wheel to cut the hose, blow it out with air before installing. People saying these are leaks or fittings don't know what they are doing have this line on my builds and the builds I do for others.
