Never had a problem sealing one of these filters but I’ll remember this little trick if I do.
F1 fernox filter
- Thread starter trevorbayliss
- Start date
Where did you put the PTFE? 
CWHEATING is right. You have to more than hand tighten.
Says so on the instructions. Infact the lid has a mark to tell you which point to tighten to. Read the instructions.
No need for ptfe or silicon. Just replace the O rings and tighten as per the instructions. Btw don't tell me you PTFEd the threads on the filter housing.
