Flex duct

[comfortzone]

after inspection of the under belly of our 2005 jayco jay feather lgt, we noticed a rip in the plastic under belly. On further inspection we also noticed the flex duct underneath was ripped, what is a fix for this without replacing the entire flex duct. Any help would be appreciated, thanks, Jim

I'm assuming the flex duct is a metal coil wrapped with a shiny mylar outer wrap. I'd use some aluminum foil tape if the tear is not too bad. If bad, it might be best to replace a section of it.

Is the plastic under belly coroplast - which looks like cardboard in construction but is made of plastic? A special tape is made for mending rips in coroplast, but I'd probably use Gorilla duct tape after cleaning the coroplast well in the vicinity of the rip. If the rip is very long, I'd probably use nylon ties similar to this to "stich" the mended coroplast together, just tight enough to keep it from pulling apart.

On the duct, if there is enough slack you could just re terminate it. If it is out of the weather a quality duct tape would make an acceptable patch.
