This plated steel plug allows you to now install and use your foam cannon, turbo nozzle or other accessory with machines requiring a short profile plug. This plug features a modified chamfer to fit a variety of machines in the residential market. There is 1.5mm difference in the neck of plug compared to our standard commercial grade QC plugs so that your coupler can fully engage and seal against the plug. Simply apply 5-6 wraps of Teflon tape or two drops of Loctite to the threads of the plug and install into your accessory.
