Our member warhead052 had asked me to do a tutorial about the valve I showed here, so I thought maybe it´s good to share this design, as it´s very simple to make, and can be used for many purpose such as pilot or firing valve even can be mod to a 3-way.
(actually I got the Idea from this topic)
I can´t fing the exact model of my push in fitting, but this one will work, for 6mm tubes
(sorry the images aren´t in order)
