Hello,

I purachesed a cat in a bag.
Was told it as an OM617 M pump with 7.5mm elements, turns out it is an OM602.
Not versed enough to tell from pics until I was trying to install it.
Problem is I bought it 6 months ago and the person is gone in the wind.

Question is, are the elements interchangable?
Can I use them in my OM617 pump and "get something" out of this fiasco.

THanks
