Using these adapters, you can no join any soft drink bottle with a standard 22mm neck to a 3/8" NPT Male Pipe Thread. This design uses our innovative #213 O-ring sealing system for handling high pressures, and also works with regular flat rubber washers as well.

These adapters are ideal for pressure testing water rockets, especially the type made using spliced bottles, and are also useful for anyone wishing to make a 2 Liter Bottle air storage tank.
