well made valve
By Randy from New Jersey

well made and obviously heavy duty. I needed to change which way the valve turned based on the mounting location in my boat and it was as easy as removing the stop nut and remounting it on the other side---there was no need to remove the handle or move any other part. I am confident that this bronze valve will hold up to the salt water that will no doubtedly be in my bilge!

Bottom Line Yes, I would recommend to a friend
