Why is it leaking though?
This is a good question
Do you have the two pieces that make up this part connected together properly? There are instructions which come with this part that explains how to use a union or column to fit the parts together, it sounds like the ferrule is slipping and leaking is occurring.
I am not a complete novice in assembling HPLC components and yes, I did read the instructions. I also know from experience that a slipped ferrule results in leakage at a different place (i.e.: the part where it is screwed into the column) while the leak I observed is locate at the place where the two parts from this filter are fit together. Tightening at this place ficed leaking, while it would not have fixed the leak caused by a slipped ferrule.
As I said, we use this part almost every day and there are no leaks. Tighten it until you meet some resistance but not so much that you cant separate it.
It is nice to hear that it works for you, It does not work for me, though.
BTW I don't seem to be the only one having this problem. Why else would Waters sell a kit containing 5 filters and nuts? This would not be necessary if people did not lose quite a lot of irreversibly tightened nuts.
