NOVA STARLINK Tight head drums, also known as closed head or 1A1 drums, have a non-removable top. One can only access the container via a 2” and ¾” plug in the top of the container.
These containers are used for the transport of liquid hazardous goods in UN packaging groups I, II, and III.
On a tight head drum, the head is an integral part of the drum construction — both ends are flanged and permanently sealed. Because of the limited access to the contents, tight head drums are often used for liquids, especially lower viscosity liquids.
