Hose is cheap and feels like plastic. Two of the fittings were wrong and had to purchase new ones. They put o rings in the JIC and didn’t realize that till they were all on. Had to take it all apart again and take out o rings. No instructions on any of it. Would not recommend, spend the extra money and get a higher quality.
