Filled with pure CO2 suitable for beer use, they also fit most bicycle pump type injectors that take 16 gram threaded cartridges. These are 3.25" long, .732" diameter, with a neck threading of 3/8-24. These also fit the simple 'bicycle type' inflators that use 16 gram unthreaded cartridges. Save a lot if you buy 30 or more.
