Put these on the wheels and didn't have any leaks at the rim. Not sure if they are just better than the Muc-off valves I had last or if I just learned better. Put some oil based lube on a pipe cleaner and run it inside the stem and over the core to help keep your sealant from sticking and clogging the valve.
Oil slick is beautiful.
Added valve cap that is valve core remover a huge plus.
Added rubber base options helped with the seal.
So far, so great! Air flows in quickly to help seat the bead.
Gravel biking three sets in three different wheelset's, work awesome!!
