If you have filled cylinders with 200 and 300 Bar DIN valves then you have probably used the really annoying one-piece DIN-to-Yoke fill blocks. The DGX DIN-to-Yoke Fill Adapter is a much better solution because it uses the same system for connecting to the cylinder valve as scuba regulators. This fill adapter has a hand wheel for easy attachment and removal, no wrench needed. Even better, because you can orient the yoke fitting a full 360°, the adapter adjusts to accommodate the orientation of the fill whip, not the other way around. That means no more fighting with the whip to attach it to the cylinder.

The adapter accepts standard size o-rings and fits all 200-Bar and 300-Bar DIN valves, but this adapter is suitable for filling only.
