Automag lvl 7 powertube ring

[Nxt1playr]

What is the size for a level 7 powertube O ring? Also are the shims suppose to go between the plastic washer then the carrier or carrier and top brass hat? This is a 68 AIR valve and everything worked fine, but now I cleaned it and it has bolt stick right before reset, then I blow out the o-ring. Yes super lubed, yes I tried red and silver springs.

Brass hat - spacer - Oring

#010 oring for power tube

The spacer allow oring compression to fit on bolt inner tube
the spacer length is use to compensate for oring tolerance from what I understand

There are no shims or carriers in a lvl 7 Automag.

There is a power tube spacer and one 010 oring. The oring goes in first, then the spacer, then the tip is screwed on finger tight.

On a semi related note I never had a problem with the original spacer spring. I never adopted the incrementally sized spacers for my original Lvl 7 and stuck with the spring until my recent "upgrade" to lvl 10.

Same here.

It is supposed to go: -10 "o" Ring in the bottom, brass spacer, cap. I recently had a level 7 bolt that would leak like crazy with the urethane "O" Rings from AGD (I tried 5 or 6 different ones new from AGD) but functioned flawlessly with a buna -10 "O" Ring from the hardware store. Not sure what that is all about but it works now.

So is this wrong then? This is how the valve came which would explain alot.

Can you take a picture of the back of the bolt, it would help to ID if its a 10 or a 7

Also look at the thread posted before there is some exploded view of the different AGD valve

Well, you have a level 10 setup there, not a lvl7 to start. Go to the AGD website and look at the lvl10 setup instructions - they should help you greatly.

I’ve had a hell of a time with my Lvl 10 mag and a leak. Even bought the AGD repair kit and still leaks..... so good luck! Maybe your issue will help with mine!

I'll add that imo, you really want to go with the original polyurethane o-rings for the automag valves. I would recommend one for the powertube instead of the Buna one you have shown there.

I had it blow the o-ring through the powertube all the way up the bolt. I'll be ordering a poly ring
