DGX Threaded Dust Plug for DIN Valve, Delrin
- Durable machined polyoxymethylene (aka Delrin) construction
- Works with either 200-bar or 300-bar DIN valve fittings
- Help prevent salt and sediment buildup and corrosion
- Vented so that the presence of gas leak does not trap the plug
- Includes swivel attachment lanyard and o-ring
Our dust plugs for DIN valves work with either 200-bar or 300-bar DIN valve fittings and include a swivel attachment lanyard and o-ring. Machined from delrin they each resist salt and sediment buildup, corrosion and damage from normal use. The delrin version has the advantage that the sides are machined with cross-hatching that makes the plug easier to grip and unscrew. They are vented, so that the presence of a gas leak does not trap the plug, making it difficult to remove.

Helpfulness
Good plug but can be dangerous
Jul 25, 2018
Great dust plug for the price but I have had two explode when the valve was bumped open enough
to blow the center out. The threaded part remained in the valve but the center section with the vent hole
was blown out. It does sound like a shot gun blast when this happens.
I was lucky, hit me in the chest, not in the face or eyes.....
I have switched out all of my Delrin plugs in favor of metal plugs.
WARNING
The screw-in type DIN valve dust plugs are very popular, but there is a safety concern. If the valve is opened while the dust plug is in place, then the tank pressure can overwhelm the relief vent and forcefully eject the dust plug from the valve. The force of the tank pressure may even be enough to cause the plug to become one or more pieces of shrapnel that could injure the diver or other bystanders. If you use DIN valve dust plugs, never open a valve while the dust plug is in place.
