Do I need an Outlet Plug?
Some people like to use the Outlet Plug when mixing formulations but it is just as easy to dispense a little material and just pour it back in a couple times rather than trying to deal with the plug. This is really for formulations that must be mixed and kept mixed thoroughly. If you are constantly renewing a base, it will be very difficult applying the plug with hot liquid. ”
People that may use the plugs are mixing lotions, deodorants, powders with liquids, etc. and require constant suspension. Even then they can be a pain to use. The outlet is 1.5”. The liquid sweeps in and out of the outlet pretty easily. Dispensing some and pouring it back in works fine. We recommend trying the process without the plug first before trying to use one.
