When precision matters, purity is everything. Our High Purity Helium Tank delivers 99.99% pure helium in a compact, ready-to-use 19g cylinder — giving you consistent, powerful lift for balloons, scientific applications, and specialty gas needs. Whether you're setting up a backyard celebration or a large-scale event, this tank delivers reliable performance from the first fill to the last.
Why High Purity Helium Tank 99.99%
Not all helium is created equal. At 99.99% purity, this tank eliminates the inconsistencies found in lower-grade helium — giving you stronger, longer-lasting balloon float and more predictable gas behavior. Manufactured in Italy with precision M11 × 1.0 threading, every component is engineered for a secure, leak-resistant connection. The 1,595 PSI fill pressure ensures you get every liter of gas out of the cylinder, maximizing your value per tank.
Unlike bulk helium rentals that require deposits, scheduling, and returns, this compact non-refillable cylinder is yours to use on your timeline — no contracts, no hassle. It's the go-to choice for decorators, event planners, and specialty gas users who need dependable purity without the overhead.
Key Benefits
- Ultra-High Purity (99.99%) – Delivers consistent, high-quality lift and minimizes gas loss through balloon membranes compared to lower-grade helium.
- Generous Capacity – Holds approximately 106 liters of compressed helium gas, providing ~31.5 seconds of continuous flow at 80 PSI.
- Italian Precision Engineering – Made in Italy with M11 × 1.0 threading on both tank and regulator/dispenser for a secure, reliable connection.
- High Fill Pressure – Pressurized to approximately 1,595 PSI, ensuring strong, consistent gas delivery throughout use.
- Compact & Lightweight – At just 1 lb, the 19g cylinder is easy to transport, store, and use anywhere.
- No Rental Hassles – Non-refillable, single-use design means no deposits, no returns, and no scheduling headaches.
- Extended Float Time – Pair with Hi-Float or polyvinyl alcohol barrier solutions when filling latex balloons to significantly extend float duration.
- Broad Compatibility – Works with adjustable needle-valve regulators and push-pin valve dispensers (sold separately) via standard 1/4" brass barb output.
Use Cases
- Birthday & Party Decorating – Quickly fill latex and foil balloons for home parties, kids' birthdays, and backyard celebrations.
- Wedding & Event Planning – Reliable one-time supply for balloon arches, centerpieces, and venue décor without rental logistics.
- School & Community Events – Ideal for fundraisers, school fairs, and community gatherings where a portable helium source is needed.
- Balloon Art & Small Installations – Perfect for balloon artists working on compact sculptures and small-scale decorative displays.
- Specialty Gas Applications – Suitable for any application requiring high-purity helium in a compact, portable format.
- Photography & Film Props – Use for floating balloon props in photo shoots and video productions requiring precise, controlled lift.
Directions for Use
- Attach a compatible M11 × 1.0 regulator or valve dispenser (sold separately) to the top of the tank.
- Connect your balloon or hose to the 1/4" brass barb output on the regulator or dispenser.
- Open the valve slowly and fill your balloon to the desired size.
- For latex balloons, apply Hi-Float or a polyvinyl alcohol barrier inside the balloon before filling to maximize float time.
- When finished, ensure the valve is fully closed.
- At end of use, completely empty the tank before recycling. Tank is non-refillable.
What Growers Are Saying
"Excellent results throughout the event season. The purity made a noticeable difference in how long our balloons stayed afloat."
— Marcus T., Commercial Event Decorator
"Easy to use and consistently delivers. No fuss, no rentals — just reliable helium when I need it."
— Sarah P., Balloon Artist
"One of the best compact helium solutions I've used. The Italian build quality is evident and the M11 threading fits perfectly."
— Daniel R., Event Planner
Frequently Asked Questions
What is the difference between 99.99% purity helium and standard helium?
99.99% purity helium contains minimal impurities, resulting in more consistent lift, longer balloon float times, and better performance in specialty applications compared to lower-grade helium blends.
How many balloons can I fill with this tank?
The tank holds approximately 106 liters of helium. The number of balloons depends on balloon size — a standard 11" latex balloon requires about 14 liters, so you can expect to fill approximately 7–8 standard balloons per tank.
Is a regulator or dispenser included?
No — the tank is sold separately from the regulator and valve dispenser. Compatible accessories with M11 × 1.0 threading and 1/4" brass barb output are available separately.
Can this tank be refilled?
No. This is a non-refillable, single-use cylinder. Once empty, fully depressurize the tank and recycle it according to your local regulations.
How should I store the tank?
Store upright in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep away from open flames. Do not store in enclosed vehicles.
How do I extend balloon float time?
Apply Hi-Float or a polyvinyl alcohol (PVA) solution inside latex balloons before filling. These barrier solutions slow the rate at which helium escapes through the latex membrane, significantly extending float duration.

Note* This is high purity helium and helium is the second smallest atom in the universe. Consider that helium nucli are so small that they can pass through gold foil without hitting other gold nucli. As discovered in the Rutherford Gold Experiment. When using high purity helium with latex a barrier should be used like HiFloat or Polyvinyl alcohol, To maximize float time on your balloon. It creates an extra barrier which slows down the rate at which helium escapes through latex.
