The Largest Gas Cartridge Device for Larger Tires
ON-THE-GO TIRE FILL
Introducing...
ADVANCED LEVEL
Model 87300 Tire Fill Kit
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.
We had aired down our tires at Island beach State Park in New Jersey for a morning of surf fishing. 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 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. Too 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.
Integrated tire valve protruding provides a realistic approach for attaching the air chuck.
Customers will be intrigued as they walk by!
