White Teflon Orings?? Where to put

[Carbon Blue]

As you all know the minimag/automag parts kit comes with 4 small white teflon orings. Where do these white teflon o rings go into? I Know there are some on the on/off but is the stock on/off on the classic valve even unscrewable? Are all 4 teflon orings used in the full rebuild of a classic valve? and how do you remove the regulator spring pin? Do you just pull it out?

You only use 2 at a time in the on/off. The rest are spares. just twist and pull the reg pin and spring out. ;) The on/off doesn't unscrew. Just pop the oring in and put one on the pin holding the on/off top on.
