Yes, any 510 model cartridge will fit the Dura-C.
You can get them off of e-smokeytreats, the janty usa site, or many others. The Dura-C has many names by other companies but its all just the same model. (The Yeti, Titan, Dura-C, Joye510, ext.) Just browse
through some of the the supporting sponsers and see if they have any cartridges for any of those 510 models. But like I said, I get mine from e-smokeytreats though.
Happy Vapin!
