There are many ways to seal something. You an use spring energized seals or you can use high pressure seals s well that are either temperature controlled or not. The high temperature oil seals that people use are the ones where they are temperature controlled to a certain point in order for the spring energized seals to hit a certain point that will make them easier to control and use within the given hemisphere. Many of the peek seals that we have seen over time and have used in order to get the spring energized seals to a good and favorable point have worked well over time and have been beneficial to the overall makeup of a good seal in the making. Whether o.r not there are people out there that see how high temperature seals work or how they are of benefit to others, it matters not because the inevitable outcome of them is what really keeps people coming back for more when it comes to spring energized seals. Too many people think that spring energized seals are complicated, but in reality they are not at all.
