I am installing a oil pressure sender via a Aeroquip braided line to the oil galley port under the I/C on an EJ20T.

Is it best practice to use some sort of high temp sealer or thread lock on the adapter going into the galley? If so which one?

Also, I was wondering about the fittings on the braided lines, is teflon tape enough to seal them? I am finding that for NPT threads most people recommend this TFE Paste, is that what you guys are using?

Edit: I did find that you are not supposed to use any type of sealer on AN threads, in case this helps anyone else out. Reference: http://www.aeroquip.com/media/techtips/TipAdapters.pdf

Edit: Further info from NASOIC: The torque specs on the galley port are ~30FtLbs, according to docs provided by www.wrxtra.com with their sender kit.

 

I did the same install...I used high-temp teflon grease on the gallery plug and teflon tape on the fittings (they are mostly NPT with one BSPT). I haven't had any leaks in the year that's it's been in place.

 

Thanks, I will use teflon paste/grease on the galley threads as you did. I assembled the NPT/BSPT parts already with teflon tape. So I think I am good to go now.

O/T, that aeroquip braided line is nice, a little hard to assemble, but man rock solid.
