Alright so no dust cap, my plan is to buy the T3 DIN and add the yoke adaptor... With this purchase should there not be some sort of protection/ dust cap for the stage one?
Hello Mark, the T3 Din does come with a dust cap. If you are looking for a dust cap to fit this adaptor: http://www.scuba.com/scuba-gear-37/034040/Innovative-Scuba-Regulator-Dust-Cap.html.
A DIN regulator can be attached only to a DIN valve, which is incompatible with standard Yoke regulators and valves. The best way to check if your valve requires a DIN regulator is to check where the two connect - if they must be screwed together, there is a good chance you have a DIN valve. If a metal brace has to go over the tank valve, and the brace screwed down to clamp the first stage, then you have a Yoke valve. DIN valve/regulator connections are more streamlined than Yoke connections, requiring less outside hardware to attach. A DIN valve and regulator can also handle higher pressures when configured correctly.
A DIN to YOKE adapter is perfect for keeping your DIN regulator when only yoke tanks are available.
