I need to order some replacement O-rings for my Russian 91%. Looking on amazon/ebay, the 2 most common materials are Buna-N (nitrile rubber) & silicone. Just wondering if these are both safe materials to be used in e-cig applications? They'll both stand up to any heat they might be subjected to, but what about the interaction with e-liquid? Will either of these materials break down, or leach chemicals when coming in contact with certain juices like some plastic/acrylic tanks will?
What are the O-rings that come on devices typically made out of? Thanks.
