Yes. Are you using this for a fire pump in EMT? That stuff is horrible to pull in a raceway.

The -2 suffix indicates that the wet rating equals the dry rating.

The OP needs to be aware that if he is trying to achieve a 2 hour fire rating with this there is more to it that just simply installing this in EMT as there are all kinds of requirements for how the raceway is installed. In other words, it has to to be installed as a "system" complying with UL FHIT.

Maybe they've improved the insulation but when we used this about 10 years ago it was very difficult to pull.
