I've got these nips screwed into my Fleck 3/4inch bypass. Still have tiny drips coming from both the inlet and the outlet. How tight or not tight should they be? I've teflon wrapped, doped, and reseated them a few times already to no avail. I could probably get a few more cranks on the nips if i wrenched it but dont want to go too hard if its not necessary.
