Hi, I'm trying to find the exact type and size plastic used on the ego 510 cartomizer tank that I ordered from madvapes: eGo 510 Dual Coil Tank Cartomizer, 2.5ml. I'm attempting to build my own atomizer and I can't find the type of plastic used
and I need it to be the exact size in order to make it fit flush with my ego battery from what I gathered the dimensions are 9/16 OD 1/2 ID and 1/16 wall thickness but I can't find the exact size 
Also what would be the best type of plastic to use?
Thanks in advance
