Threaded Plugs
The threaded plug consists of a basic plug and the respective threaded adaptor. To align the plug on the cell vent, the basic plug is able to turn on the adaptor after installation – a solution for which bfs holds the patent. All parts on the inside and the outside of the plug housing are fitted as form-locking components. This means that the plug can be disassembled and all its parts recycled at the end of its operating life.
