Includes valve, refill tube, and cone washer with nut.

Review: A perfect pump for when you Take a Dump - This appears to be an actual Toto product and was easy to install and works great to fill the tank after flapper engagement. My OEM fill valve randomly stopped working after about a decade of heavy use. Highly recommended and seems to fit most Totos.
Review: Fits most toilets (not just Toto), easy to fit and adjust! - Excellent product. Very easy to fit and adjust. Instructions come with a table showing the height/fill settings for Toto products, but it fits pretty much any toilet - adjusting the water height in the tank is simplicity itself - just move the filler column up or down until it’s the right water height, then twist the column to set it in place. Done. I swapped my old one out in about 10 minutes from start to finish. Now I have no leakage or extra noises. Well done Toto!

This was my first time having to replace a fill valve, and I was surprised at how simple it was (watched a couple of YouTube videos). This replacement works great in my Toto toilet - no problems at all, no leaks. Highly recommended!
