DIN Plug with Viton O Ring

DIN Plug with Viton O Ring


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.
