Donā€™t put Coax outside without sealing it

Iā€™ve used this stuff for 25 yearsWhy did you pick this product vs others?:Iā€™ve used this stuff for 25 years. Never had a Coax failure with this stuff.

Coax seal works

This tape worked great. It really sealed the joint and was easy to work with.

Easy to use

This moldable butyl rubber product is an important part of weather sealing coaxial cable connections. A commercial radio professional friend taught me to wrap the coax with GOOD electrical tape with the sticky side out. Wrap with the Coax Seal and wrap with a final layer of the electrical tape sticky side in.

Impermeable and very long lasting

I've been using this stuff on my amatuer radio antennas and any electrical connection I have outside. It stays flexible, like putty. And it does not leak, and does not come off. I have left it in place for 30 years on aluminum and copper. When I remove it, the copper is still shiny, and the aluminum looks like it's new. Great stuff.

Q
Quin
Great product. Price way too high.

Works well sealing cable connections outside. Price is too high, but electrical tape just won't do the job in many situations.
