2. A way to regulator the output of the tank (referred to as 2nd-stage regulator)
3. A connection or line to feed air from the regulator into the blaster
4. A blaster with an air in-let that matches the airline type.
Depending on the inlet of the blaster and the desired connection type, you’ll need a handful of fittings.
The easiest way is to use Push-to-Connect fittings as they’re cheaper and easy to connect.
If you want to use one-way air valves so that you can disconnect your air without removing your air source first, you can use quick connect fittings instead.
Any fittings that do not already have a sealing surface, like an o-ring, on it should have its thread sealed with thread tape (teflon tape).
