Our economy Inflator works on all Helium tank cylinders with a hand-tight connection. Flex-Tip valve allows a user to inflate latex balloons easier and is available with or without a gauge. We also carry an inflator that automatically fills all size foil balloons to correct pressure and volume. Easily connects to the cylinder with a hand-tight connection. Never pop a mylar balloon again!Our rentals include the use of an inflator, so there is no reason to purchase one unless you are interested in keeping a tank long term.
