Use this insert to convert any 200-BAR DIN style SCUBA cylinder valve for use with any yoke style first stage regulator up to the DOT rated maximum SCUBA cylinder service pressure of 3442 psi. The DGX insert has an 8-mm hex opening and includes two oxygen compatible 112 O-Rings.

Does a yoke adapter insert exist for the 300 bar valve? No. An adapter insert does not exist, and even if it were made, we have never seen a yoke clamp long enough to fit over the 300 bar SCUBA valve. There is a yoke-to-din fill adapter device for 300 bar valves, but it is strictly for filling only.
