An interesting idea.. idea of dual coil cartos...

[unloaded]

The cartos fit inside the red rings. Once in they are sealed with O-rings and held by a SS ring. To get them out you push the red ring to release them. I'll double check at work that these are the right brand that fit. We've got a sales rep that comes in and keeps them stocked. The one pictured is a Norgren Push Fit Parallel Y with a Male stem.

I'm thinking Dual, Dual coil at 1.25 ohm may be the point where we have to start looking out for Nicotine toxicity. =] Let us know how hard they are to remove. If it is too difficult it will be hard to top off.

A single is easy to remove but if you have the wrapper on the carto it will probably scratch it up. I was actually fitting one in a manifold that had 6 connections on it, toying with a bulk fill idea.
