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.
The Machine Plug and Hose connector connects the soft hose to a testing plug (bung). The small barbed end secures into the soft hose (236046), the large barb inserts into neoprene plugs with center hole allowing for secure leak free attachment.
