DGX HP Sealing DIN Plug w/Viton O-Ring

DGX HP Sealing DIN Plug
DGX HP Sealing DIN Plug
  • Eliminates accidental gas leaks from your valves
  • A true HP O-ring seal for 200-Bar and 300-Bar valves
  • Perfect to protect $$ Trimix fills
  • Travel and move filled tanks with confidence

The HP Sealing DIN Plug provides a true high pressure O-ring seal in both 200-Bar and 300-Bar valves; it's primary purpose is to prevent gas loss from leaks. The typical use is to protect an expensive (or just plain important) gas fill from accidental loss while the cylinder is being handled or transported. Our design is chrome plated brass, exactly the same material as your valve and thus is NOT subject to galvanic corrosion and galling. We have seen that happen with other plugs made of a dissimilar metal; all that's needed is a little saltwater moisture and then the plug seizes in the valve.

The moment a DIN HP Plug is removed from the valve it seems to grow legs and walk away, so screw it into the first stage DIN cap from your regulator and secure it with the lanyard. If you discover you are unable to remove the plug by hand because it's being held in place by the pressure of the gas trying to escape, close the valve and break the seal by loosening the plug with a wrench.

  1. Very nice

    I am now using these exclusively on all of my tanks. I like keeping my O2 bottle sealed for safety, and safeguard against losing expensive fills of O2 and trimix.

    On air or recreational nitrox fills, I remove the o-ring from the plug and use it to to protect the valves and keep out dust and bugs, but it won't pressurize and stick.

    If you have the o-ring in and accidentally pressure it, it's not the end of the world. You just have to give it about a quarter turn with a 1 inch wrench to break the seal, but I wouldn't put my valves through the extra abuse over air or 32% etc.

    Really nice piece. Came with a plastic cap that can protect a DIN connection.

    Solid built, watertight and not going to become a rocket when you accidentally roll your valves.

  4. Works well at a good rice point.

    I have several of these DIN plugs and the work well. They are Brass so they are less apt to mess up the threads than the SS ones and will no blowout if pressurized while they are in unlike the plastic one that can become a missile if the valve is accidentally opened with one in the valve.
    I also have a SS plug that is heavier, bigger, cost a lot more and has no hole for an attachment string.

    A word of warning. If the lug is in and the valve gets opened you will need a good size wrench to get it out. The good thing is you will not loose a tank of gas.
