As I look at the regulator Thor uses.... it is a really crappy design.
Most of the better two-stage regulators are assembled with screws holding the two halves together. Thor uses one form GASFLO and the two halves are crimped together.
Here are pictures comparing the one Thor uses to other two stage regulators. I think I am going to order a better one from Amazon and then I will keep the replacement Thor sends me as a spare.
