I received the product in just a few days. It is an OEM product, an exact replacement, and installed easily. One bit of advice - install the Viton seat with the blunt end of a 5/32" drill bit. I tried to do it with a little piece of wire, and buggered the first one. This was my second attempt (had to order a new one) with a new seat, and it worked like a charm with the drill bit!
