We’ve been doing this for decades, and we know how to do it right.
Steel Cartridges Filled with Carbon Dioxide (CO2)
The Maximum Inflation® brand of CO2 Cartridges are different. It is because they come from a heritage of over 50 years of being used in the inflatable life jacket industry where quality, cleanliness and performance are absolutely required for life safety.
The precise amount of gas is verified as it is filled into a pristine clean cartridge. Decades and millions of cartridges produced have provided us with the knowledge and technical ability to elevate the gas cartridge into a performance component. The total weight of the cartridge is proportional to its safety. The CO2 is so dense inside the cartridge it is almost liquid. It is a gas which wants to boil even at very low temperatures. The gas that boiled off into a vapor, is what goes into your tire. But you noticed the outside of the cartridge gets cold. That is the effect of the gas ‘stealing heat’ from the steel cartridge body to allow the conversion from liquid to useful vapor.
Once you realize that the internal pressure of a CO2 cartridge can reach over 3,000 PSI when it reaches 150°F (65°C) you come to appreciate the inherent safety of Maximum Inflation® brand CO2 cartridges.
Packaging for Gas Cartridges
Grab-n-go
These visual product dispensers are compact and allow consumers to choose the quantity they need. These grab-and-go style dispensers save thousands of plastic packages from entering the waste stream. Maximum Inflation® brand continually explores ways to bring you the highest value possible.
Hang it up
Clearly defined value packaging.
Based on feedback from distribution, offering cartridges in hanging packaging allows retailers to have options depending on their specific store needs.
Everyone Gets a Chubby™!
Grab yourself a little “Chubby™” protection.
What we really love about the “Chubby™” sleeve is that it stopped the rattle in our tool bag. Slip it on for much protection against a cold CO₂ cartridge. Dealers can request bags of “Chubby™” sleeves for the 16/20g crowd and the larger 25g size for the adventurers in the crowd.
Packaging
We are updating our "hanging" CO₂ packaging to have one Chubby™ in each package. Maximum comfort when discharging a cold CO₂ cartridge.
The small Chubby™ fits our 16g and 20g cartridges, while the medium Chubby™ is solely for the 25g cartridges.
"Stealing Heat"
The CO₂ is so dense inside the cartridge it is almost liquid. It is a gas that wants to boil even at very low temperatures. The gas that boils off into a vapor goes into your tire. But you noticed the outside of the cartridge gets cold. That is the effect of the gas ‘stealing heat’ from the steel cartridge body to allow the conversion from liquid to useful vapor.

Steel Cartridges and Cylinders Filled with NitrAr (N2+Ar)
NEW - FOR PRO RIDERS ONLY
Performance cyclists know that consistency is paramount. The track temperature changes and so does the pressure in your tire unless you start off with NitrAr® in your tire. Is it a miracle gas? Not exactly.
It is science that you can use to optimize tire pressure under changing external conditions. Everything leaks, it is a question of how much. We experimented with the same set of tubes over the course of months of filling, checking, deflating, refilling, temperature cycles, and even road use. CO2 leaked quickly, air not as much. But the data showed that Nitrogen with Argon added proved to be the best combination time after time. Consistently.
-
Stable pressure at various temperatures
-
45% less leakage compared to CO2
-
24% less leakage compared to regular air.
Air has 21% Oxygen, good for our lungs, but it is an oxidizer gas which degrades thangs like rubber compounds over time. That decomposition allows the already porous tube to be even more porous, leakage rates increase.
NitrAr® is a proprietary Nitrogen blend with Argon (large molecule). Total purity is 99.5% minimum. No air or CO2 added. Pure performance in cartridges and big cylinders.

‘The Big Deal: 1.9 Liter Cylinder of NitrAr Nitrogen Blend’
The NitrAr® program is only available to professional shops and qualified race teams. The cylinder is charged to 1600 psi and does require our regulator fill kit 44000 in order to get that pressure down to a range of 10-80 psi or our direct pressure filling kit, non regulated, model 49000 which allows very high filling pressures. It is so powerful we require a waiver to be signed!
Here is a quick look at what you would expect to get out of the big 1.9 liter NitrAr® filled cylinder.

Why a Top Off Cartridge is needed?
The smaller cartridges are roughly the same 21ml body size as a traditional 16g CO2 cartridge but since they are filled with gaseous NitrAr®, we can’t call them ‘16 gram’ because the gas itself is so much lighter than CO2 and that would not be accurate. The net gas weight in a 21ml cartridge filled with NitrAr® at 2600 psi is roughly 3.4 grams.
These NitrAr® cartridges are for those purists who have already filled their tire with Nitrogen or NitrAr® and need to add a few more PSI. As we have said, everything leaks, it is a question of how fast. NitrAr® is the slowest leak rate gas blend that we have developed so far.
Gas Filling Equipment
There is a great sense of gratification when you can instantly fill a tire from a gas cartridge. You immediately get back in the game.
Filling Valves that Puncture Cartridges
ENTRY LEVEL
Model 50018 Tire Fill Valve
The famous model 50018 tire fill valve for Presta or Schraeder tire valves. Weighing in at only 32.8g, you get our lightest filling valve with a standard 3/8” threaded inlet, seal, and puncture pin. The gas flows when you push the body against the filling valve. Remove it, and the gas stops.
When filling with CO₂, it is always best to try to hold the cylinder upright, small end upwards. The simple reason is that the CO₂ is so dense inside the cartridge that it behaves like water. Gravity can cause liquid CO₂ to run into the tire valve. No bueno. That can freeze your tire valve and that can complicate the filling as the tire valve may not close properly if it is buggered up with frozen bits of CO₂.
PRO TIP: Filling too rapidly with CO₂ causes a ball of dry ice to form inside the cartridge. You will not get all the gas you paid for.
Glass filled nylon with machined inlet, this little inflator is listed as an entry level device, however, we have sold these to pro riders who are very concerned about weight.
These are set up so you can use them on Presta valves as well as standard tire valves.
We have not touched this design, a proven reliable winner for over 25 years. Typical retailers are seeing significant increases in sales once we put these into a grab n-go bulk box for the counter. Customers cannot believe how light weight and durable these are. We are not playing with a good thing.

The Next Great Inflation Valve
ADRENALINE LEVEL
The Maximum Inflation® brand is working on the next generation inflation valve. Taking into consideration feedback from users of the existing inflators out there, we have found several key factors towards making history:
-super light weight
-compact
-built in pressure gauge
-low carbon footprint
-recyclable materials
-long life seals
Pricing on a superior custom-made product is always a concern. The new design is being developed and made in the USA. Making the design ‘manufacturable’ is a prime consideration. If you are interested in participating in our testing protocol, please reach out.

Model 87300 Tire Fill Kit
The Largest Gas Cartridge Device for Larger Tires
Aircraft Aluminum and Stainless Steel
Our exclusive, the legendary model 87300 Maximus® valve is a special breed of gas dispensing engineering made in Minnesota with design inputs from Japan and our in-house NJ team.
The Maximus® 5/8” valve shown with 18” hose and a Schrader/Presta filling chuck.
Many of us have tried out the electronic battery mini compressors. And it is so true, you get what you pay for. Another thing to charge and remember to charge. That did not help us when someone in our group brought out their $49 battery inflator. We had aired down our tires at Island beach State Park in New Jersey for a morning of surf fishing and it worked for about 3 minutes until it didn’t. So disappointing and a very slow drive on 6psi tires for the next hour.
Leland® Maximum Inflation® brand CO₂ and N₂ cartridges are welded closed. They are going to have the gas inside ready when you need them.
The Maximus™ kit is a legacy product, one designed to be passed down to the next generation of adventurer in your family. The gas will be in the cartridges, long after you are gone. You know a quality well designed product when you pick it up. It’s ok, we smiled too.
Specially Designed Inlet
The gas inlet is a 5/8” thread that mates to the Maximum Inflation® brand 74g CO₂ or 18g Nitrogen cartridges.
The inlet is specially designed to provide long term durability with its stainless-steel puncture pin which has a built in 40-micron sintered screen filter. Unmatched performance is guaranteed with this very special valve. The outlet is a 1/8” NPT female thread, making it widely adaptable to many standard fittings.
Thumbs Up
You would be surprised how long it took to get this feature dialed in. To narrow, too short…we thought our engineers were going to throw one at us. We are outdoor adventurers, and we know what it takes to get the gas out of a cartridge, even a big one like the 74g size. Leland Gas Technologies has been in the gas cartridge business Since 1965. ISO9001 Registered.
