What’s your reason for doing this in Dynamo? If you’re replacing all fittings (of a certain type?) then just select all instances in project and then change the type. If you have too many types to manually select then you could create a schedule to group types and select that way.

Please provide more information and show what you’ve tried so far. This is not a forum for asking for solutions. You need to provide some effort towards the solution.

if you will do that then all fiiting will belong to you pipeseries…but possible

Hi Nick. Its realy hard to replce for example all tees in project by another tee ( it crash,…)

Dynamo won’t fix this. You’ll need to make changes in smaller groups then.
