ICON 12483 Rubber Grommet, 1-1/2"

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.

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.

So your rv grey water inlet broke a leak or God forbid the black tank, in my case it was the grey tank and these were exactly what I needed to fix my problem some say it should be a tight seal fit but just incase I slammed some silicone all over mine just to be safe but very pleased.

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

Worked. I like it because it was not a glue fitting and can be removed if needed.

Perfect fit fast on the delivery time also and great price too thanks !

Just what I needed, Worked great.
