What has more vibration---your IO360 or a CAT bulldozer---careful with the answer. Think about it--

What about EZ Turn lube on flair fittings. The product sold through Aircraft Spruce is supposed to be, I thought, specifically for this purpose.

As your building, or re-building, a good practice is to apply torque seal which is a great visual inspection aid that will validate 2 things..one, that you have torqued it for final time, and second, it will visually let you know if it is loose, or has been loosened during inspection or maintenance. I torque seal mine at the B-nut and the ferrule /tube. I prefer bright orange, but lots of colors available. In fact, I do the same for every bolt on the plane.
When I do a tech inspection, if it doesn't have torque seal on it, it isn't torqued.
There was a recent article in Sport Aviation or Kitplanes showing torque seal applied but was kind of messy. I never do it this way, neatness counts. To avoid the torque seal slipping and giving a false positive torque reading, I run a very nice bead all the way along a line from the hose barrel to the flange nut on the fitting. This way, if the b nut rotates, it will break the torque seal on the flange nut. Here I found neatness counts. It the torque seal is messy, it is hard to tell if it broke loose. And if the torque seal does not have good adherence to the flange, it wont break when rotated.I’ve had mixed results with Torque Seal. When checking some B nuts in my fuel system I discovered a few were loose after a few years, even though the Torque Seal looked perfect. What I found was that the hardened Torque Seal was slipping around the threads. So I don’t trust it much anymore and always put a wrench on these fittings to make sure they are tight.
