The MLBSML Goof Plug will fit and plug all standard holes punched with a standard size .160, .170 or .190 hole punch for common barb and other emission devices.
For larger holes punched with .190 or .195 (large) hole punch into three-quarter inch tubing, you will need the larger MLBLRG Large Good Plug. Three-Quarter inch tubing requiring the large goof plug is usually only found in commercial applications.
Almost all residential drip mist systems require the MLBSML Hole Plug.
