Duct Seal Usage Rating Outdoors or in Vehicles.

The temperature usage range for Duct Seal is 25 to 120 degrees F and it has a tolerance range of -30 to 175 degrees F. This means the Duct Seal should be applied between 25 to 120 degrees F. Duct Seal is used and designed primarily to plug holes around conduit mostly inside buildings but is also used outside on service entries. There is a tendency to dry on the surface when exposed to weather. There is material in these locations that are dry but still maintain a seal after 20 years. As far as use in vehicles, there shouldn’t be a problem unless the vibration causes the material to not adhere to the surface.


Duct Seals Reaction to Gas Vapors and Liquids.

Duct Seal is resistant to gas vapors however, if condensation of gases occurs then it becomes an issue. Liquid gases contacting duct seal can soften the material. Gases themselves are not the problem but liquid formed by condensation over extended periods could be an issue. Duct Seal is not meant to be used outdoors.

Do you have a tester that can trace romex cable like a wire tracer?

There are a few different tools that we offer for tracing wire/cable in the home or for commercial applications. Regardless of the type of cable all of our units are capable of tracing cable. Each unit has what is called a “tone generator” or a transmitter that sends a tone over the cable that can be picked up by the receiver or “wand”. Below are some of the tools we have that cover this, all of which can be used in either commercial or at home applications.
