Din Plug for Regulator, Delrin - RGPB9253:
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 high-pressure gas does not trap the plug, making it difficult to remove.
