Putting up several antennas and want to find the black goop cable installers use on the inside connector threads and center pins . Im well versed in outter sealing. Was on a forum somewhere here but no one ever mentioned the INTERIOR CONNECTOR THREADS OR CENTER PINS . Can someone point me in the right direction , closest I Came was Ebay from England a $6 tube, with $25 Shipping, No Thanks, maybe have something at local auto store ?? and not BULB GREASE ...
COAX CABLE CONNECTOR METAL THREADS

The only thing I've ever seen for use inside an RF connector was Teflon based "Stuff" brand grease and its white. It has a dielectric constant similar to Teflon. After testing it for several years in a commercial DirecTV broadcast center environment I stopped using it and I don't see any value in it whatsoever. A good outer sealing per Andrew/Commscope specs can last a lifetime with no internal goop needed.
Beware of some silicon sealers because they release acetic acid when they cure. Particularly bad on silver connectors. A well intentioned ham "sealed" some feed throughs at a repeater site. We had to replace all the connectors.

Yeah, you don't need that. I've never seen it used in the industry. Manufacturer specs, like prcguy said, are what you should follow. I know hams seem to like it, but if you seal the outside correctly, it's not needed.
Well I Found mine today , made by GB OX-100 intended to keep internal connections from corroding . OH I Guess internal connections were completely void of ever corroding , Rigggggght ........Keeps water from creeping into connector Threads. BLACK GOOPY , dont have to use much at all . Does not interfere with RF .
I have been using dielectric grease on the center pin and threads and where the antenna threads into the mount for years with very good results. Auto parts stores and big box hardware are good places to find some, as well as online.
Reading SPECS on Newer GB OX-100B Increases Conductivity . Prevents corrosion between dissimilar METALS , A BIGGY AS there is Lead , Chrome, Steel, Copper , to name a few . At least someone other than me has common sense .
Well, I guess you showed them. Enjoy your connections.

Lead? Chrome? Steel? Copper?
Let me guess, cheap Chinese ham radio grade connectors? UHF connectors at $1.00 each? 10 each for $7.50?
Good coaxial connectors are not made like crap. They use silver plating, gold center pins. I don't think waterproofing is your main issue. The main issue is you are using crappy connectors.
Don't fall for the hype and lies, it won't do anything for you or your connectors. Some of us here have 40 years and more experience making tens of thousands of connections, some critical for audio passing through recording studio equipment and some to the maximum usable RF frequency of coax connectors in the 70+ GHz range. We know that nothing is needed on the inside of the connector to make a perfect connection that will last a lifetime.
If you believe the hype then send in your $$ and have fun, but don't try and convince us that its the bomb sh*t and that we are loosing out by not getting some. Those who know better will be sitting in the back row trying not to laugh out loud. There are also some very experienced folks out here that are no doubt insulted by you shoving your misguided opinions down their throats.
And please turn off the big stupid bold font, it just brings more attention to your insecurity and lack of knowledge on many subjects.
