I have PL-259 and N connectors in use that are likely that old however none
have stayed connected anywhere near that time frame. It is a good question
but you cannot really complain about 25 years of service. I do not apply
anything inside the connector and use quality connectors such as Amphenol
and Andrew/Commscope. W8JI has an article on grease and he states
conductive grease should never be used in RF connectors.

After over 25 years I've found some problems with connector conductivity at
my 4X4NJ station. I would be interested in knowing about experience that
any of you may have with reliable connector conductivity for similar time
periods. This is primarily with PL-259, N-Type, and hard-line connectors
and associated adapters. In particular, any experience with the following
would be helpful:
1. Nothing done to ensure conductivity
2. Silicon grease
3. Penetrox (or similar)
4. "STUF" dielectric water proofing filler
I'm interested mainly in actual experience that you have had after many
years of using any of the above, or other, methods. Please note that I'm
not seeking methods for waterproofing - just in keeping the connection
between mating surfaces highly conductive assuming waterproofing is good.
