O-Ring Specifications

[Earthy]

Can anyone tell me what the specs are on the o-rings that come in a mag tune-up kit? I live in Canada and the postal and duty to order a kit is a bit steep. There's also a local industrial store that sells all types of o-rings so I was hopeing that I could buy my 0-rings for my mag locally.

Thanks

It's pretty sad that nobody has bothered to reply to this thread at all.

Like Earthy, I'm in Canada and have access to industrial suppliers for o-rings. I'd like to know what all the o-ring sizes in the Classic Automag are.

Anyone?

Not trying to sound like a jerk but take the o-rings to the supplier and have them match-em. :cheers:

Great idea!

I'm going to get a set of rings for the 'mag (not tearing mine apart without spares) and have a shop match 'em. There's a local supplier that'll do Buna-N 90-duro rings.

I'll post back when I find out what all the rings are.

Let us know how those o-rings work.

I got my hands on a set of precision digital calipers yesterday.

I've measured every o-ring in the Classic Automag parts kit twice now and matched up which one is for what part of the marker. I've used the same descriptive names for each o-ring as is used in the AGD Classic Valve Exploded View document. http://www.paintball-parts.com/downloadFiles/air_gun_designs_classic_valve_exploded_view.pdf

Two of the sizes are very common and I've listed AS568 "dash" sizes for them. For the others I've simply listed my measurements. If/when I find out what common size they are, I'll post back.

My two references so far have been:
