ICON 12483 Rubber Grommet, 1-1/2"

Worked as it should, perfect fit.

Good thickness to the rubber, should hold a long time. Although I don't need this, I accidentally ordered it. It is a well made product.

Awesome works perfect I put in the Grease Trap inlet hole for my sink drain pipe in my food trailer.

Looks like good product some information on hole size to be drilled to install product would be nice

These work nicely but you will need to soak it in very hot water. Boil water and then remove it from the heat source and pour the hot water into a container with the grommet in it, enough to cover the entire thing. Wait 3-5 minutes, then fish it out with a screwdriver or something, dry it off with a towel (so you don't have hot water on your fingers, because the rubber itself is hot and hard to hold, and then promptly begin installing the grommet. I used this method for a 1-1/2 inch one and it worked well. I did have to use a mini pry bar I had next to me to get the last but to go into the tank but it didn't take much force, and it didn't damage the hole in the tank. I didn't bother with any sealant, since this is just a grey water tank, and it's on the top, so it should be good and sealed well enough. Use dish soap or blue glass cleaner to lubricate the pipe you are going to be pushing through the grommet and rock it back and forth gently while pushing, and it'll go in nicely.

Quality rubber don’t know how long it will last. We don’t want a leak on our back water tank.

Didn't work for what I needed them for

It fit the top inlet of our grey water tank perfectly. I thought I would have to rig something or use just a sealant until I found this.
