This small insert makes a HUGE difference in the Flexburner flame! Replacing the standard nozzle screen with the Stabilizer Insert produces a hotter blue flame with a tighter shape for more heat right where you need it. More efficient combustion results in a less reducing chemistry as well.
No tools required for installation, simply pop out the screen and press the insert into the nozzle! Works on all Flexburners and Flexburner XL's
