E/FUSING 112 - Flame Resistant High Temperature Silicone Electrical Insulation Tape 1 in x 30 ft

Works great on sealing up my PL-259 on the choke going to my Mosley PRO-67 B Amateur radio beam on a tower 50ft up in the weather and will last for years keeping out the moisture.

easy to use and it adheres and seals well.

Used this to seal joints on pellet stove, worked great been on vent pipe for over a year and still holding tight

Good isolating electrical tape for high-temperature applications. I use an inside gas fireplace, behind the burner, to isolate the spark ignition line when touching metal and to limit high-voltage spark leaks.

All the reviews claiming this does not stick - they are not stretching it out first. If you keep it tight while wrapping it around the cable (or whatever you want to wrap), it sticks very strongly to itself. Imagine stretching something like an ACE bandage and you will get the right result. It does not just "stick" to itself either - it is hard to describe, but it really seems to "bond" to itself and create a thick continuous wrap. Even though it bonds to itself, it does not leave behind sticky residue. It does not create any gummy goo like some kinds of these weatherproof cable wraps. It removes extremely cleanly with just a knife. Of course that was just testing for a few days - time will tell how it holds up over years.
