The one I got is stainless. There are different lengths to be bid on. It comes with mounting brackets so you can use it on anything. The over flow tube attatches to one tube on the bottom. There is another tube that runs up higher inside that is an overflow if the tube fills all the way up. The top unscrews and has an oring to seal it. It came with brackets, screws, rivets to attach brackets and hose clamps too. More than I expected. I am happy with the product and result. Just wanted to pass on what I thought was a good deal.
