Gardner BenderDS-110N Duct Seal, 1 lb. Pug

I bought this product to be able to stick to the bottom of my kayak and connecting my depth finder. It is a great product. It is very sticky. The quality is great. It was very easy to

For those who might not know, this is basically a pound of waterproof sticky clay-like stuff that is used to create a weather seal around open ends of conduit and the like. It's exactly what it says it is, and works well.I have a gutter downspout that empties into a 4 inch drain pipe. It frequently gets clogged by needles and debris from my fir trees. This stuff let me create a seal between my square downspout to the round cast iron drain pipe. I used the leftovers to plug up some small holes in my furnace ductwork.It's not very malleable when cold, so warm it up first by rolling it between your hands first until you get enough to form around whatever you're trying to seal, then pack it in.The product info says it's "non-conducting, non-deteriorating, non-toxic, non-corrosive, non-staining, non-curable." So it won't harden up or stain.Also, it's non-toxic, but it's sticky and has an odor to it, and the residue doesn't wash off so well. I'd suggest using a pair of nitrile gloves when handling it.

it's sort of like a putty that seals openings from the outside of a house.

And I've spent decades looking for it again.I keep it right next to my duct tape and bailing wire.Totally Recommend

If you ever worked on an air conditioner and wondered what that gummy, sticky stuff is around some of the lines and fittings is, this is it. Use it to help seal, as well as a vibration dampener, and to keep bugs and other pests from getting in through little openings and nesting. A specialty product that works well for what it is, and seems to stay at least somewhat flexible after a few years, yet is stiff enough it doesn't droop.

Thanks to a gap around the exhaust vent over my stove, mice from the attic got into the cupboard and made a disgusting mess. This stuff plugged the gap, no mice so far!It's super sticky and left a gray oily residue on my hands. I tried wearing latex gloves but it's so sticky they fell apart. Anyway it got the job done, holding well to exposed wood and metal duct work, good value for the price.

Used it to seal ends of external conduit running low voltage wire from antennae to house.

This is a great product for electric applications to seal from envirement

Worked just as expected. After checking on it after 20 days elapsed, I found that the putty becomes rubberized and is no longer malleable (which is a good thing). 5/5
