This cylinder plug is used to cap the cylinder neck threads to contain the liquid and tumbling media while tumbling. During the process, the cylinder threads are protected from damage from the tumbling media by the long thread of the plug (30 mm in length). This plus is suitable for M25 x 2 threads.

The plug can be tightened or loosened either by hand or 17 mm spanner.

Made from Acetal, the plug also comes with NBR 214 shore 90 o-ring seal.
