The orifice of these tips and the viscosity of our innovative BOSS™ foaming liquids are calibrated to provide the perfect mixing ratio when using our Auto-Mix metering system. The Auto-Mix system takes the guesswork out of snow foam... No mixing, no mess, no math, just screw a bottle of foaming concentrate onto the cannon and get ready for a blizzard of foam. The pink tips can also be installed in the Griot's Garage Foaming Sprayer when the sprayer is used to dispense any BOSS™ Foaming System liquid.
