Are there such things as Bottomline Expansion Chamber???

Not that I have ever seen. Doesn't mean someone did make one at some point. There is however a Female Stabilizer from Palmers.

I already know that. And there's "female" Hybrid regulator too.

But exp. chambers.. I just never see any bottomline ones.

Probably because there isn't one. A regulator is better anyway.
