Agilent 1290 Infinity Heat Exchanger

I am replacing the heat exchanger part that goes between the primary/secondary heads on Channel A of a 1290 Infinity binary pump (G4220A).

The old part is shown on top in the photo below. I ordered Part # G4220-81013 listed in the manual (and the diagram in the manual looked like the old part). The new part that we received is the silver-colored one at the bottom of the photo. It looks like it can fit, but I was wondering if one of the Agilent engineers can confirm if this part is indeed compatible and the correct part that we should be installing?
