This is a brand new, genuine Symmons Temptrol volume control diverter, model TA-25A. If you have a Symmons shower system and the diverter (the thing that switches water between the showerhead and tub spout) is leaking or not working, this is the exact OEM part you need. It's made in the USA, comes unused in its original packaging, and is built to Symmons' quality standards. Installing this will restore proper function to your shower/tub combo. It's listed under the brand \Symmons generic,\ which just means it's the official part without fancy retail packaging. A must-have for plumbers or handy homeowners dealing with a faulty Symmons valve. Much cheaper than replacing the whole unit!
