O-ring Sizes

sunshaker · 06-10-2010, 10:01 AM

I'm not sure if I have the right sizes but this is what I measured them as right from the rebuild kits if anyone can confirm, correct, or complete this list by all means go ahead. All O-rings are 90 Durometer Urethane (except where they are listed as Teflon).

Classic Valve (for Automag 68 and Mini-Mag; 1 rebuild)
4 Power Tube O-rings 010
4 Teflon O-rings 006
2 Barrel O-rings 018
2 Reg. Piston O-rings 012
1 Reg. Body O-ring 116

RT Classic (1 rebuild)
3 Field Strip Banjo O-rings 009
3 Barrel O-rings 018
2 Power Tube O-rings 010
1 Reg. Piston O-ring 012
2 Reg. Seat O-rings 008
1 Reg. Body O-ring 018
2 RT On/Off Small O-rings 004
4 RT Reg. Valve Pin O-rings 006

Level 10 Bolt (1 install)
2 Carrier O-rings 008
1 Power Tube Tip O-ring M1.78X7.94?!? (I need to confirm this. Is this the same Size as would be found on other mag valve tips? I had a dead one in an old Mini-mag that I couldn't figure out the size for, but I replaced the Level 7 with a Level 10 and didn't need it anymore.)

X-Valve (for RT-Pro, RT Custom, Emag, and Xmag; 1 rebuild)
2 Power Tube O-rings *
1 Reg. Piston O-ring *
3 RT Reg. Seat O-rings *
1 RT Reg. Body O-ring *
2 RT On/Off Small O-rings *
4 RT Reg. Valve Pin O-rings *
5 L10 Carrier OD O-rings *

Emag On/Off O-Ring (sold Seperate from the kit above)
4 Emag On/Off O-ring * Quad (this is a special O-ring that does not have a circular cross section, the cross section looks more like an X)

Flatline Reg (for Flatline 3000 psi and 4500 psi Tank Regs)
1 Body O-Ring *
1 Seat O-Ring *
2 On/Off Cam O-Rings *
1 Piston O-Ring *
1 Small O-Ring *
1 Tank O-Ring *

* I don't know the size for these at this time (mostly because I don't own them).

Thanks for posting this...I'm about to replace the o-rings in a used RT(built in 2006) that I just bought. I've also used a real old Classic so I dont really know anything about the X-Valve and LVL 10 so forgive my ignorance, but wouldnt the specs on the O-rings listed under the X-Valve and LVL 10 be same specs as the O-rings listed under RT Classic? Isn't the RT just a mag with an X-Valve and LVL 10?

I can confirm that the Classic valve on/off Teflon o-rings are indeed size 006. I bought some 006 Teflon rings (also called PTFE) for another project which ended up not working. But they are an identical replacement for the on/off rings in my Classic mags.

AGD sells three different kits a Classic Valve kit, an RT Valve kit and an X Valve kit (also for RT Pro and E/X Mags), this indicates that there is a difference between each kit (though I don't know what).

From what I hear:

The X-Valve O-Ring Kit has a couple of O-Rings that are slightly different and also has a few LVL-10 parts that aren't in the RT Classic Kit.

You know you just answered your own question. Using the wrong size o-ring will either result in a leak or the o-ring not fitting (I have no doubt that the o-rings in the X-valve kit are all 90 Durometer Urethane just like every other o-ring AGD uses). Which would be why they come as a separate kit.

Classic RT parts kit includes O-rings for the banjo bolt. *AFAIK*, there is no difference between the X-valve and Classic RT valve besides the 1)air input, 2)outer diameter of valve body, 3)valve body materials.

Useful thread, thanks.

Can Buna-Nitrile material o-rings be substituted for Urethane material o-rings?

ASKA · 12-15-2010, 03:55 PM

Anybody know the size for the Level 10 powertube rings? EDIT: nevermind. called them up. It's also a 008

LGswift · 01-28-2012, 08:53 PM

Does anyone know what size o-ring seals the powertube to the on/off assembly of a level 5 valve?

Cheers,
Ethan
