Mansfield 630-0204 2" SmartFasten Tank to Bowl Kit (Black)

I tried generic, after market kits and they all leaked; inevitably costing me double the work. The key to this design is tightening each bolt down to make the seal. A few extra turns makes all the difference. Easy to install and works very well. Highly recommended.

Perfect fit. The attachment screws were different but work well.

OEM fit and quality made the job easier. No leaks at all.

Much better than the bolts & washers.

I bought this because I had a slow leak from one of the original screws. This solved the problem after a little trial and error. There are two flaws with this design. First is that you have to tighten all the screws evenly at the same time. This means, once they're snug, giving 1/4 to 1/2 turn on each screw in turn. If you try to tighten one screw all the way and then move to the next it will cause the tank to sit at an angle. The second issue is that the same nut tightening the tank to the bowl is also what applies sufficient force to hold the rubber to the tank hole to prevent a leak. So if any of the screws aren't tight enough you end up with a slow leak. Generic screws generally have two nuts. One holds the gasket to the bowl to prevent a leak and the second holds the bowl to the toilet. To be fair, i'm not sure which design is better. The last thing to watch out for is that the holes to attach the tank to the bowl are lower than the normal flush hole. So any residual water will drain out the first screw you loosen. It's a lot more water than it looks like too, so make sure you have a bucket ready. A towel isn't enough.

Easy to install and works great. I purchased this kit for because I was removing the tank and wanted to make sure nothing leaked after assembly.

Perfect replacement. Exactly what I needed for the job.

Everything you need to install the tank onto the base. Had no leaks
