Tire 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 Valve that Punctures Cartridges

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.​

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.

How to Fill Tire with CO₂ Properly

​When filling with CO₂, it is always best to try to hold the cartridge 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.​​

Glass-filled nylon with a 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.​
