I’m happy to obtain this part for my older stainless steel tank. It is an original quality CHAPIN part that was a great value and shipping was not extra. Although I have not yet used it, now I know my old CHAPIN sprayer is ready when I need it.
Best part of my purchase was the customer service department that replied to my concerns almost immediately and kept me aware of the ship date.
It took a few weeks for this part to arrive but it functions like a new one. Didn't seem exactly brand new and shiny but these were probably last made quite a few years ago. Rubber gaskets and valve diaphragm were pliable and not dried out so it sealed properly and worked much better than the original it replaced.
