Why We Designed It | Product Specs | Getting Started

Why We Designed It:

With only a handful of manufacturers in the world producing compressed gas cylinders, SILCA sought to find the best and most reliable source.  We found a supplier best known for producing automotive airbag inflators as well as life vest inflators for both commercial and military aircraft.  Cartridge threads are precision roll-formed to guarantee both size and thread strength. Custom molded helmets protect the threads and gas seal insuring that your cartridges work when you need them.


  • Contains 2x 16 gram Cartridges and 2x Impact Helmets
  • 100% Recycled packaging and recycled linen paper cylinder labels
  • Please Recycle Cartridges after use!
