There's 4 big reasons why buying a tank is the best choice for you.

10% Savings compared to renting

When you own a Helium 2 Rent tank, refilling it is 10% cheaper than renting a tank of the same size. So not only do you get to keep it as long as you want, it's cheaper to refill compared to renting a tank.

Allows you to keep unused helium

Normally when you rent a tank, you have to return the unused helium left in your tank. But if you own your own tank you don't have to return it and can save that helium for your next party. This works especially well with 2 small tanks.

Free maintenance / lifetime warranty

Owning a tank usually comes with responsibilities, but with Helium 2 Rent we'll take care of everything:

DOT certification, 5-year hydrostatic testing, damaged/leaking valves, loose handles, worn/removed safety labels.

Every time a tank is exchanged it gets serviced, filled, and put back in a store. So every tank you receive is good to go!

100% trade in credit towards upgrades

If you ever want to purchase a larger tank then you can simply trade in your tank and 100% of the amount you paid for it will be applied towards the purchase of the new tank! Just pay the difference.

How It Works


The first step to owning your own tank is to decide which size you want. A detailed selection of our helium balloon tanks for sale is below, as well as a balloon calculator to help you estimate how many balloons each tank can fill.


Once you've decided on a tank size, go to our Orders & Locations page and select a Partner Store near you. This will be the store you pick up your tank from. After you go through the checkout process and pay, that tank is reserved for you to pick it up whenever you would like.


When arriving at the store, tell the store employee the name for the order and they will hand you your tank and demonstrate how to use it. They will also check the pressure of the tank with a regulator to show you that it is full. It is the customer's responsibility to visually verify that their tank is full. There are no refunds. Once the tank is in the customer's possession, it is their responsibility to care for it to ensure there is no helium loss. Refer to our Operations & Safety page for proper care and usage.

After you receive your tank you can take it home and keep it as long as you want, it's yours! When your tank is empty, order a refill from our website. Then bring your empty tank to the Partner Store and they will exchange it for a full tank of the same size. Even though you're getting a new tank, we still refer to it as a "refill" but you can think of it like a swap or exchange.

Lastly, to fill balloons with your helium tank you need to use a regulator. Buying a tank does not include a regulator, it must be purchased separately. You don't have to buy the regulator from us, there are many different types of regulators available at other stores online. We offer a regulator that can fill both latex and foil balloons which you can find when you checkout.

Balloon Calculator

We created a Balloon Calculator to help you compare the tanks before you buy one. If you would like to use it, simply select the size of the balloon in the left column and put the amount of balloons in the right column. It will add up the volume needed to fill those balloons, and suggest a tank size for you. This calculator estimates round latex balloons only.

This calculator should be considered a broad estimation. Volumes vary between balloon manufacturers and if the balloons are over/under filled. Because there are too many variables, Helium2Rent cannot guarantee all balloons will be filled by the suggested tank. Helium2Rent can only guarantee the volume in each tank is correct, that our equipment is in working order, and that our helium is 98% pure.

For reference, here are our 3 tank sizes and the volume of helium they contain.

Balloon Buddy: 27 cubic feet

Party Animal: 60 cubic feet

Show Stopper: 150 cubic feet

Our helium balloon tanks for sale do not include a regulator. Listed here are all the regulators we sell. There is only one difference between them so picking one should be easy. If you don't like our selection, you don't have to buy the regulator through us, you can purchase one online if you wish. Any regulator that has a CGA580 fitting will fit our helium tanks. Our Partner Stores carry both sizes so if you order online you'll pick it up at your chosen partner store.
