An inflation valve assembly comprises a longitudinally extending conduit, a cap, a normally closed elastic double-duckbill valve, and a hollow nozzle insert. The longitudinally extending conduit has a first longitudinal end and a second longitudinal end. The cap is configured and arranged for removable attachment to the first longitudinal end of the conduit. The normally closed elastic double-duckbill valve sealingly engages within the conduit with intersecting radially elongated slits extending longitudinally there through. The hollow nozzle insert is configured and arranged for longitudinal insertion into the conduit through the first longitudinal end for separating both slits and opening the double-duckbill valve so long as the nozzle insert remains inserted within the conduit.
