Might be a long shoot, but I'll try. I'm looking for the environmental seal, hydrostatic transmitter and cap for a Apeks DS4 regulator.
Thanks, Al

I am guessing you want to convert a US4 to a DS4. The environmental end cap does not screw directly on to the main reg body. There is an extra piece, Diaphragm Clamp, that scews into the main body, the spring adjuster screws into the Diaphragm Clamp then the Hydrostatic Transmiter then the Hydrostatic Diaphragm and finally the Environmental End Cap.
If this is the case it may be cheaper to pick up a used DS4 on eBay than buy the parts from a dealer.
