This Griot's Garage replacement 1.1 primary jet will deliver enhanced foam production from low-psi pressure washers generating 1,540 CU (Cleaning Units = gpm x psi) or less. THE BOSS Foam Cannon comes equipped with a 1.25mm primary jet, and includes one of these 1.1mm jets.
What to look for...
Watery Foam: If foam output is not rich, thick, and lathery, there is too much water being injected into your concentrate. Alleviate this by inserting a 1.1 Jet.
Pulsing: If the cannon is pulsing, emitting inconsistent foam, or if your pressure washer is performing erratically, your primary jet may be too small. The higher back-pressure will intermittently trigger the machine's auto-shut off function.
