I love how we can all nerd out over O-rings.

I’m not sure if you guys are kidding or serious, but petroleum
products will probably attack the rubber.
On something like a Ceragon mount where the O ring doesn’t slide over
a tube but just presses against the other surface, you’d probably be
better off just going without lube. Otherwise, you could use the old
photographer’s trick for filling scratches – nose oil.

It's one of the things I usually forget but always have a vehicle
near, so I just pulled the dipstick out and get some oil off it.

I think you mean DC4 which is dielectric grease. The chemical
composition is probably similar to DC111 but it isn’t as
stiff. DC111 is basically a food grade lubricant for rubber
valve rings. I suspect that plumbers grease that you buy at a
hardware store is similar stuff. DC111 probably has silica
added to make it thicker.
If you like the single use packets instead of 5 oz tubes, I
think these are probably the same thing:

I always used DC-40. I bought it at the airplane shop.

Do you lube the O rings on your licensed antennas? I have
seen some where they didn't and the O ring cracks apart,
potentially causing water ingress.
Most of the big names include a small pack with the radio
or dish. I am struggling to find the exact product. I
have heard people say that you can just use Vaseline, but
the Internet says the petroleum will eat the rubber o ring
within about a year. I see dielectric grease also being
reported as being used, but it will supposedly also melt
the rubber.
Most are recommending Silicone Grease. The only silicone
grease that I can find locally is "100% pure Silicone
Grease" that is "Spark Plug Boot Grease". I figure that
spark plugs boots are also rubber so this is probably the
stuff, but it is also listed as being dielectric, and it
contains polydimethylsiloxane.... whatever that is.
Does anyone have any recommendations for what I should use
to lube the O-Rings on my licensed backhauls when they do
not include a tube of whatever they usually include??
Anyone have any stories about things that did not work out?
