Pfister Hot and Cold Faucet Valves

From a box of new and used parts, They have a nut attached to them, which leads me to believe that these were installed, but you could not tell it looking at the hose or valve, but the nuts to hold it in place either came from the replacement and were not installed or they were very lightly used. You are purchasing both the cold and hot and they come to you exactly as pictured in the photos we have provided.
