Remember that you need to buy two end caps for a tank, if you don’t have them already.
The new end caps have a slightly larger external diameter so they’re easier to hold when during fitting and removal.
They click into place and are easy to remove without breaking your nails or tools.
You can use all Siam and PM tanks in either 35 mm or 55 mm height. With that you need tank cartomizers of the same length.
2 end cap large round "GROOVE" surgical steel.
2 internal o-ring
2 external o-ring
With each end cap you get two extra o-rings:
an external ring which is a bit thicker than the one already fitted so it’s suitable for glass tanks (pyrex)
an internal ring which is a bit thinner than the one already fitted and is used with BOGE cartomizers, which are slightly thicker than those from e.g. SMOK.
REMEMBER to always moisten the internal o-rings with a bit of e-liquid before inserting your cartomizer. This makes it easier and prevents damage to your o-rings, just like it’s a good idea to hold on to the cartomizer’s white silicon plug and replace it when inserting the cartomizer in the tank.
The end cap fits both Pink Mule and Siam’s glass and polycarbonate tanks.
