DotShell / VapeShell MTL Air Flow Pins Kit is common for both the DotShell and the VapeShell and includes:
-One Air Flow Pin with Inner D=1.0mm
-One Air Flow Pin with Inner D=1.2mm
-One Air Flow Pin with Inner D=1.5mm
They reduce Positive Tube’s initial D=4mm down to D=1mm, D=1.2mm and D=1.5mm respectively, offering the ideal air flow for a substantial range of MTL vaping profiles. And this, with optional use of the fine adjustment of AFC Ring.
An o-ring around their body allows easy installation plus perfect fitting inside the Pos Tube. The o-ring is black NBR or Sil70 clear/red, depending on availability.
On top there is an auxiliary laser engraving “1.0” , “1.2” and “1.5”, standing for inner D= 1.0mm, 1.2mm and 1.5mm respectively, to help you distinguish among the three small diameters.
DotShell / VapeShell MTL Air Flow Pins are made of 316 Stainless Steel.
