Kanger OCC heads - red or white insulator?

[DingerCPA]

I just broke open a new OCC head (0.5ohm) for my Nano, and I noticed that the replacements have a white insulator at the positive contact pin. The coils that came with my tanks all have the red insulator. Good, bad, other?

(I do rebuild my heads, but I was too lazy this evening, so I decided to crack open a fresh coil....)

The ones that came with my ST Mini (black o rings but old rba base) were red and labeled 5A.

I purchased two packs of OCC coil heads. One was with a Kangertech branding, white insulators and was labeled 5A. The other one had a InnoCigs branding (german distributor of Kangertech and joyetech products), red insulators and was labeled 5B.

All are authentic and I couldn´t notice any difference except the colour and labeling.

I recently got a pack with the red insulators, I am hoping they are a bit more heat resistant and will not scorch as easily as the white do when rebuilding the OCC's.

My tank came with coils with the white insulators, the replacements had red.
