COAX SEAL 1/2" x 60"

Coax-Seal is a special material which will quickly and effectively seal all types of coaxial fittings of any shape from moisture, water and corrosion. Coax-Seal stays flexible for years thus insuring moisture proof connections. Insures good SWR and long coax life. Coax-Seal also allows you to disconnect and reconnect fittings with the same material by simply re-forming the plastic. Coax-Seal is the only material that will adhere to vinyl and poly vinyl connector outer covers. Coax-Seal is non-toxic, non-corrosive, non-conducting, and has hundreds of uses in electronics. 1/2" x 60". Stays flexible at any temperature.

This is a hard to find item. Used to be common in Radio Shack, but they stopped carrying it. It was expensive, especially with the shipping added in... but it works great.

This stuff is amazing, use it for sealing coax connectors, keeping radio control heads stacked on top of each other, and anything else that you want to seal, or not move around. A little brother to Duct Tape, lots of uses.
