Sorry. I should have said the quick disconnect (QD) on the hose has a Schrader valve. This is unfortunate because it turns a high flow hose into low flow-just like standard inflator connectors. The new SP inflators also have standard male Q.D. fitting. As far as I know, internally the inflator assembly itself remained the same. Fortunately, the male fitting can be easily removed and replaced with the older high flow fitting. Likewise, the female fitting can be easily replaced with the high flow (AIR 2 and older inflator) Q.D.Are you saying the new SP inflators use Schraders?
