RectorSeal Duct Seal 81880 Compound, Easily Applied to Plumbing & Metal Fabrication, Paintable General Purpose Sealant, 1 lb

This is a unique product. It works well to seal up holes in electrical boxes with wire passing through. Easy to knead and shape. Not sticky to the hands but stays in place very well. Too soon to tell but seems like it will stay pliable and not harden. Bottom line a great product for sealing up those holes in the wall through out the house where plumbing or wire passes through.

Worked very well for sealing air leaks in my HVAC ducting. No mess, No fuss, easy to work with. Great product.

Love this stuff works great for my application, the consistency of the product is nice and firm, looks like it's gonna stay flexible for a while and you don't have to worry about it drying out, it's a nice thick product that will be compatible with a lot of your applications. You can use this for a lot of different things, it'll be compatible with so many of your projects ones especially where you can't use grommets because of space constraints or anytime you need a extra seal on something, this stuff is great, most of all it's not supposed to dry out so that makes it really useful.

This product has been great to work with. It’s clean, easy to shape by hand, and doesn’t create a mess. The seller also offers a fair price and ships quickly.

I used it to patch holes around my air handler.

After recently residing my house, I needed a block of this material to seal the gas line's service entrance. Although the gap was small enough to seal with a bead of caulk, this stuff is easier and less messy to apply with the same result. Product Quality: It's tough to determine this type of material's quality visually although I've used this material and brand before and it's an excellent, moldable, non-hardening sealant. Product Use: Fresh from the delivery truck in 30 degree weather, the block was stiff, but still moldable. It became increasingly malleable with the rise in indoors temperature, reaching clay-like moldability. Although this material is sticky, it leaves no sticky residue on either hands or applied surfaces. Final Thoughts: If you need to seal the wire or pipe poking through your wall to the great outdoors, this is the stuff to use. It's less messy than caulk, arguably longer lasting, and there's considerably less waste material. Since it's non-hardening, it should last if stored properly. And it's a third of the cost on Amazon as at the big box store! I bought second block "just in case."

In greater Chicago area houses have to have conduit inside the walls. This unfortunately can cause condensation inside the pipe if a run supplies bathroom and then travels into an unconditioned space. This condensation happens to land on both my garage door opener receptacles causing gcfi to trip. Ended up stuffing the inside of conduit to make sure no airflow occurs and it seems to have worked.

I came across this duct seal compound online and figured it would be a good idea to keep a bar in my workshop for future use. At the time, I didn’t have a specific project in mind, but it has already proven its value. I noticed some small gaps around the screens of my raised foundation and decided to give this compound a try to seal them up. It worked perfectly for what I needed. Even though I believe the compound is more commonly used for insulation-related sealing, I was concerned about bugs or small critters getting through those gaps. This sealant applied easily and gave me a solid, secure seal. I haven’t painted over it yet, but visually it looks like it’s holding up well. I ended up using almost a whole bar for this project, but I’m happy with the result and plan to pick up another bar just to have on hand for future repairs or sealing jobs. It’s always handy to have something like this around, and it’s proven to be a versatile solution.

was easy to use for putting around pipes coming out of fridges

"I used this to seal around the electrical conduit where it enters my house, and it was so easy to work with. It’s like a soft modeling clay that stays pliable, so you can really pack it into gaps to stop drafts and bugs. Unlike spray foam, it’s not messy and you can actually remove or adjust it later if you need to. Great price for a very effective product!"
