I purchased this item and found no gaskets with it. I plan to use these isolator valves with a Taco 0011 pump and am curious if gaskets are required. I would suppose they would be but there's no mention of them on the package instructions.

Gaskets are not included with Webstone Isolator valves, but are included in box with every flanged Grundfos or Taco circulator, so there's no need to buy extra.
