Our tapered neoprene plugs are offered primarily to help you plug holes in order to locate and isolate leaks. They are most often used when using the MAG Machine in order to seal off sections of tubing, the instrument’s bore, tone holes, and ports. These are also used to plug tubes on brass instruments when cleaning, stripping, polishing and lacquering. Neoprene plugs are essential tools that belong on every serious technician’s bench.

Measurements listed are for the Bottom Diameter, Top Diameter and Length in inches and mm.
