Review on Grundfos 519602 1 Inch Cast Flange by Warrick Dembo

Revainrating 1 out of 5

These flanges are not designed for pumps or piping.

I bought these flanges to use on a pump. As it turns out, although the threads come with a rubber ring, they are not tapered and cannot be used for plumbing work because. cannot be compressed. That cost a lot of frustration and money. The seller may not understand what he is selling.

Pros
  • NPT End Connections
Cons
  • Operating Speed
