Iwata air valve o-ring

Hi

I was wondering how to replace that o-ring as it is in "gun shaft". Do I use plier and go manualy inside the shaft and retreive/put back the o-ring ?

It's the piece #7

And since I'm talking about o-ring, the o-ring 5 that goes on piece 19, is it mandatory

Does anyone uses “industrial” o-rings for replacements?
Not sure what you are calling "industrial", but I purchase the majority of my o-rings in bulk from a place called "the o-ring store". The majority of o-rings used in airbrushes is Buna-n or nitrile, so I just figure out what sizes I need, and generally order 50 or so at a time. If you mean different material, well, I have had some custom ones made before. Commercially, there are not many other compounds available in sizes we need, that are cost effective to use.
