The Ninja Magna Cap is a unique alternative to the normal rubber fill nipple cover that tends to be easily lost or damaged. One of the most important parts of your air tank to keep clean is the fill nipple.
Magnetic Cap provides an easy attachment to prevent dirt or debris from entering your air system
MADE IN THE USA
Patented Magnetic design
Helps to keep the dirt out
** PLEASE NOTE: **
The Ninja Magna Cap will only work with an Iron/Ferrous Fill Nipple, Aluminium is not magnetic!
This will not work on Empire or Valken Bottles, unless the fill nipple has been changed.
