Summary

Download and print our Soda Bottle Thread to 3/8" NPT Male Thread Adapter and use it to create compressed air storage tanks, or for pressure testing Water Rockets.

Using these adapters, you can 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 multiple spliced together bottles, which you can learn more about if you check out our homepage http://www.USWaterRockets.com. These adapters are also useful for anyone wishing to make a 2 Liter Bottle air storage tank.

Post-Printing

After you print this adapter, you should cut the 3/8" NPT threads into the hexagonal side using a Tap or by carefully cutting threads with a male pipe. You also need a #213 O-ring to seal the bottle neck (or a flat rubber washer like the kind used on garden hoses).
