Poor gasket surface
The gasket surface is very uneven and NOT machined flat. I believe a step was missed in the manufacturing process. You should buy genuine parts, they are flat. The Grundfos flanges I also ordered are perfect.

Works well
I have an outdoor wood furnace that heats water and circulates into the house for heat. It uses 3 circulation pumps and of them started leaking at the gasket, this product was perfect to reseal the pump to the pipe, no more leaking.
