Vapor blast gun with interchangeable fittings to quickly adjust performance and adapt to different compressor setups. 

You can choose to use NPT threaded fittings if selected in options (NPT Fittings Not Included)
1/2 NPT Thread for the water inlet
1/4in NPT Thread for the air jet
Metal fittings can easily crack the body if over tightened, be easy or use Nylon fittings. 

This gun outperforms any other gun I have tested
It seals perfectly and has zero leaks.
Performance can be adjusted and parts can be replaced.

The air jet and nozzle can quickly and easily be changed out to accommodate different compressor setups, and to adjust the performance and finish quality. 

For optimal performance you want to use the largest air jet your compressor can support, without draining while operating.
Once you determine an air jet size, choose a nozzle that is about 2x to 2.5x the air jet diameter.

The nozzle can quickly be changed out to adjust performance. 
A nozzle with a smaller diameter can be used for more aggressive cutting and removing tough dirt and grime.
A nozzle with a larger diameter can be used to achieve a brighter, cleaner, and more uniform finish. 

Everything included.

      Helps get fittings tight as possible without out cracking or breaking anything. 

Everything is made out of high quality thermoplastic that is high strength, and has excellent water, chemical, and UV resistant properties.
My original plan was to machine all these parts, but I've found this material has many advantages over metal parts inside the cabinet. 
This material does not corrode at all inside the cabinet, and holds up extremely well, much better than expected.

I mostly blast with glass beads, and have never had to replace any fittings or nozzle due to abrasive wear.
