Delrin Din Tank Plug

Delrin din plugs are a must for your din tank valve, its make from a tougher than steel, machined plastic that threads into your tank valve. It also has a air bleed so that if your tank turns on with the cap in, it will release the pressure slowly and allow you to remove the cap. Great for keeping your din valve dust and dirt free, especially if you are using oxygen clean tanks, just keep the plug clean. Won't cause interaction with brass like aluminum plugs.
