More PG = less tank crackers?

[IgnorantCig]

From what I understand, VG is the thick stuff, and PG is thinner.

So, is it correct for me to presume that ordering juice with high PG levels (80 pg/ 20 vg), is going to be less of a tank cracker than the same juice if it were high in VG?

I highly doubt that matters, it's more about the flavoring components used and if they are reactive with plastic polymers or not.

Glass tanks is really the only answer if you are concerned, or plan to use known tank cracking flavors.

Doesn't make a difference. It is certain flavors which react to plastic tanks, not PG or VG...

Thanks for the replies.

I knew that certain flavors are more likely to crack a tank than others, but I wasn't sure if the VG or PG levels played any part.

Glass tank it is! Thanks.

They (PG/VG) might make some scientific difference at certain level, but not in the situation/use we're concerned with.
