Here is what THEY say... "If you like a high heat style of vaporizing or just want a totally cleanable cap, this one's for you. Designed primarily for concentrates and cooling devices, it's fully interchangeable with the standard cap. There'll be no charred wood with this guy. The cap comes with an L shaped hex wrench and spare screws for easy disassembly for cleaning. A debris screen is installed in the cap to keep the interior clean. To use with Concentrates: Place your concentrate on a bed of ground material or a small ball of cotton." So, yes, for concentrates but also made to be disassemble able and to generally handle higher heat. If I needed to replace my cap for some reason, or if I were buying new I think I might go with the newer design just due to its greater durability, even tho I am a flower user.
