dumb diphragm question

[Bluetooth]

Sorry this is a really dumb question and your probably going to tell me to look it up and i did and i didn't find anything so does a diaphragm need a spring behind it?

[schmanman]

no, the pressure alone is enough to seal the diaphram against the barrel.

You only need a spring behind it if you're pressurizing the gun from the front of the diaphragm.

[SpudStuff]

Use the spring because it keeps the Diafram in place

[noname]

You don't need one. My coaxial works fine without one. I made the rubber circle a little bigger than the pipe so it fits with the edges curved back and friction holds it there.

[turbohacker]

yeah, first thing i do when modding a new valve is to take out the spring, you dont need it
