It sure is Ed. The Replacement Rubber Grommet for RV Gray Water Tanks item # F02-2105 is designed for 1-1/2" nominal PVC or ABS pipe, which is the standard size for most RV gray water drain lines. It fits polyethylene gray-water tanks with a 2-1/2" drain pipe hole.

The item # F02-2105 is intended to be used without sealants as the weight of the water pressing against it will seal the lip to the inside of the tank.

What kind of RV or trailer do you have?
