Brass Filler Cap and Bung

This filler cap and bung are most commonly used for oil tanks or any other fluid containers, such as an overflow tank that does not need to be vented.  We make a vented version of these filler necks as well.  This kit comes with a brass cap and a weld-in bung made from the material of your choice.  The cap seals against the bung with a replaceable rubber o-ring that is installed on the cap.
