Pablo –
We had to replace our cracked floor flange in our RV, so I ordered this kit to replace it. It comes with everything you need including a new flush ball seal. All the parts are equal to OEM quality and everything fit perfectly. The replacement took about an hour and is easy to do. At this price point, with everything that comes with the kit it is an excellent value.
