Filter fc0170

My only concern with the filter is that it fits correctly when I use it in 6 months. The old filter I had been using previously, fc0170 is female thread but it had a slight maybe 1/4 or 1/3 extended lip where the thread is, where this one, same fc0170 does not. The newer one is flush. Hopefully this is still the correct filter.
