+The simplest way to connect a 12 gram CO2 cartridge is with a quick-change adapter. This type of adapter is very common, and can be found for $10-$20 on eBay. It is intended for use in paintball, allowing a paintball marker to draw power from a 12 gram CO2 cartridge instead of a remote connection.
-To calculate the pressure for any non-given value, use this equation, but note that the pressure can't go above 800 PSI (the vapor pressure of CO2).
+A full CO2 cartridge is placed in the adapter's shell. The shell is screwed tightly against a pin. When the cartridge is pierced, CO2 will rapidly expand forward through the adapter. Generally, each CO2 cartridge is single-use.

+Quick-change adapters have male "ASA" threads. ASA is a paintball-specific thread size that is nearly identical to 1/2" NPT threading. However, ASA threads are parallel and rely on an O-ring for an airtight seal whereas NPT threads are tapered and thus seal automatically.
