Low cost, Hi-Temp plugs for internal threads, tubes, tapped holes and internal ports come in three proven types. The Tapered Plug, (TP series), allows just three sizes to mask six internal diameters. Insertion Plugs, (NP series) seal against liquid immersion and are easily applied due to the length of the tab. Nut Plugs, (MCP series) will both mask and also function as shipping plugs.
