Customer Reviews for Gardner Bender 1 lb. Plug Duct Seal Compound

my air conditioning air handler is in an unconditioned attic. This seals around where the line set enters the air handler and also around where the drains for the condensate come out of the air handler. I also used some to seal around the thermostat wiring where it enters the air handler. It works perfectly. Air conditioner manufacturers leave a lot to be desired on air handlers as far as being airtight. You don’t want your air handler, pulling in hot, humid, attic air during the summer.

I have used this for a number of sealing applications mosty HVAC and it really works well. For sealing A coil area on A/C and refrigerant lines it is much better than duct tape.

First time using Gardner Bender. I was a little skeptical at first, but it turned out great. A little challenging since I never did any kind of repairs like this before. But it made it easier to work with since you can bend, stretch, twist or cut to any size and length.

Did the job to seal openings at penetration points between electrical box and home.

I use this for various use. In this case to fill in the end of rotted out vinyl window sills to seal the ends after repairing them. I also use to hold fasteners when i need a third hand while on a ladder.

I’ve used something like this before and it works great to plug holes going into your house.

Quality product to seal seams or whatever you need to keep dust or moisture out. Easy to use and form it to need, to make a clean seal.
