plumbing question

[Dozer]

Ok, I'm going to be doing the plumbing for a Sequence Dart pump on a closed loop. It was suggested to me that due to the large amount of vibration on this pump teflon tape would not be the best thing to use on the fittings. So, I'm wondering which of these two things I should use instead that I bought at Lowe's:

1) Gunk plumber's silicone grease
2) Great White plumbers paste

Or I guess option 3 would be something else that I should have bought instead of either of those.

Hahaha ... no vibration on this pump and I used teflon tape without a leak!! I put 1/2" of rigid insulation under it because I had it.
