One thing to note if using these adapters with the ATX style Apeks 2nd stages:

The set screw in the adapter is directly lined up with the plastic seam on the regualtor mouth port. Turn it down to much, and you will bow the mouthpiece in and possibly split the seam. With the tight fit and silicone sealant, I don't think the set screw is neccessary; however, as a design improvement, I would move the set screw to the bottom side of the adapter where it makes contact with a solid (non-seamed) piece of plastic where it can make a positive contact with damaging the seam. I'd probably take a small drill bit and make a 1/32 deep dimple in the mouthpiece port for the set screw to sit in.
