Hello:

Is it safe to use the typical GE RTV silicones against a Polyethylene (PE)
coax outer jacket ?

I know the RTV's use some type of acid (acetic ?) to cure the stuff, and I
was wondering if
anyone might have any first hand experience if there is any kind of
interaction with a coax outer jacket ?

Thanks,
Bob

Although Bob isn't asking about sealing connectors, this thread has
drifted that way.

If this is indeed his need, then I offer my method. I use
Plymouth-Bishop No. 122 rubber tape followed by an overwrap of a good
quality vinyl tape.

If memory serves, I bought the 122 at Home Depot, although their web
site doesn't show that they carry it anymore. An electrical supply
house would likely be a source.
