I bought it without checking the part number, but it was something like a valve and something. It was cheap, so I was looking for something to come, but I was surprised to open it. Well I can not use this. I think what it is like to sell it by registering what is not a valve as a valve. I'm sorry but I ordered it to disagree. I thought it would be nice if there were bookmarks that could fly to the product number catalog etc of the manufacturer as well.
