Very easy website to navigate. I look forward to receiving the items that I ordered and to give you even better feedback if they arrive in good condition and within the timeframe the website estimated. I wish you and all your family and friends a wonderful holiday season and a very merry Christmas and joy filled new year.

It fit

It was quick and easy

A+

Great product as described but I did have to repaint them because there was some rust showing through the paint

I think for the part I ordered the shipping price was too high. Needed the part so had to do it.

I hope that the copper gaskets really seal.
