The D250-Combo Disposable Helium Gas Cylinders are suitable for inflating average numbers of latex and foil balloons with helium gas. An easy-fill nozzle is attached to each of the light-weight cylinders. When the adaptor nozzle is depressed, the helium gas dispenses. There is also an open/close valve on the top. Unused helium gas can be stored safely for future use. Non-flammable gas. Do not inhale helium gas and always inflate balloons carefully so as to maximise the helium gas supplied.
No balloons included.
Inflation: The D250 Helium gas cylinders will approximately inflate any of the balloon combinations below with careful inflation: 250 x 9" latex balloons or 135 x 11" latex balloons or 135 x 18" foil balloons. 
THESE CYLINDERS MUST NEVER BE TRANSPORTED BY AIRCRAFT AS PRESSURISED CONTAINERS REPRESENT SIGNIFICANT DANGER TO AN AIRCRAFT HOLD. THE CIVIL AVIATION AUTHORITY MAY PURSUE CRIMINAL PROCEEDINGS OR IMPOSE HEAVY FINANCIAL FINES AGAINST ANYONE BREACHING THEIR GUIDELINES. (Full information can be obtained by contacting the CAA at www.caa.co.uk) THIS MEANS CLICK4 IS UNABLE TO SEND THESE CYLINDERS OVERSEAS (INCLUDING EIRE & N.IRELAND)
This helium gas cylinder can be despatched on its own or with any helium balloons you require.
Make or Buy a Balloon Sizer to get the best from your Cylinders: Simply cut a 9,10 or 11" diameter circle from a flat piece of cardboard before inflating balloons. Inflate balloon in the middle of the cut-out and stop inflating when the balloon touches the sides of the template. This avoids over-inflating balloons. Click4 has manufactured these for your convenience which are available below to purchase. (Reusable & suitable for 9"-12" balloons)
