@ 4-WAY TIRE VALVE REPAIR TOOL 7/20T (B8973) (359G)

I USE THE BIGGEST FEMALE THREADED END, SCREWED ONTO THE TUBE STEM,, THRU THE RIM TO KEEP THE STEM FROM FALLING BACK IN, ONCE THE 2ND BEAD IS ON..

THIS REMOVES GOOD AND BAD VALVE CORES

IT ALSO IS A THREAD CHASER FOR THE INSIDE AND OUT OF THE VALVE STEM

AND IT WILL ALSO HELP TO INSTALL TUBELESS RUBBER VALVE STEMS
