Large cores for very large wheels
These are not regular valve cores, they are made for very large tires that need huge amounts of air to fill. I got these for my wheel loader with tires 6 feet tall and 3 feet wide, and they work great. Over the years, the old cores had begun leaking, and it was a pain having to air them up all the time. Now they need air much less often! Good large cores!

No leaks on HVAC charge port
I installed one of these cores on a 410A HVAC system. They have a heavy pin spring and in my opinion a quality Teflon outer seal. NO LEAKS.
