Here is a handy and useful little item; a straight Schrader valve stem for the tubeless pneumatic tires on electric scooters, ATVs, dirt bikes, mini bikes, and other powersports machines. The diameter where the stem mounts is 11 mm, which translates very close to 7/16" in non-metric measurements. The metal screw-on cap is included.
Straight valve stems have their place, especially on scooter rims that use tubeless pneumatic tires. This very handy Schrader valve may be used on any rim with a 7/16" (or 11 mm) valve hole.
