Q: Are these reusable, or is a new one required for every tank replacement?

A: As often as a tank needs to be replaced, we suggest that the grommet should be replaced too.

Q: Will this work for an ABS black pipe going into an RV black tank?

A: Yes

Q: For installation, does it just snap over and into the tank?

A: Yes, there are two flanges, and the lower flange goes into the tank. The upper flange will be on the outside of the tank. If installed correctly, the tank wall is between the two flanges.
