This is
ONLY true if the adapter is too long. The right length adapter will have the top of the valve stem just below the lip of the adapter, the same way the pin on an SV is. Since adapters are brass, or aluminum, they're easy enough to file, so everyone can solve this problem (if they have it) themselves.
