Yes they are.
Camco also have ones the same size for a 10 gal Suburban water heater tank.
The one on Ebay are really reasonable for two for $29.99 with free shipping and no tax.
I actually bought 4 of them because if you keep water in the tank they will dissolve as they are suppose to.
Mine last about 1 year but I use my rig a lot.
They range from 9" to 9.5" in length
3/4" nipple threat
But you need a 1 1/16" socket to get them out.
I also added a copy of the 10 gal DSI Subrban water heater
