The only tool thattruly cleans fuel nozzles.
Compressed air alone can't remove debris from aircraft fuel nozzles — it just pushes contamination deeper inside. NozzleFlush uses pressurized flow through all air holes simultaneously, forcing debris out for good.
Traditional cleaning methods don't work
Blowing compressed air from the top or bottom of a fuel nozzle only moves debris around inside — it can't escape. This leads to recurring misfires and potential in-flight engine problems.
Blowing from the top
Forces debris deeper into the jet's metered orifice — a funnel shape that traps contaminants.
Blowing from the bottom
Air escapes through larger air holes instead of the tiny jet orifice. Debris gets wedged in the upper air chamber.
Soaking in solvent
Loosens deposits but doesn't remove them. Freed particles relocate inside the nozzle and cause future blockages.
How NozzleFlush works
NozzleFlush seals around the nozzle and pressurizes air or fluid through all barrel holes simultaneously — the only way to flush debris completely out.
Insert the nozzle
The fuel nozzle seats into the NozzleFlush tool, creating a sealed chamber around the barrel.
Pressurize
Air or cleaning fluid is pressurized into all air holes simultaneously, flowing through the entire air chamber.
Flush clean
Debris is forced out the bottom of the nozzle assembly — or upward through the jet using the slide mechanism.
Cleaning the Air Chamber
Pressurized flow enters through all barrel holes, sweeping debris out the bottom of the nozzle assembly.
Cleaning the Jet
Insert the slide to block the bottom exit, forcing air upward through the metered orifice — blowing contaminants out, not in.
