I don't have one, but...

If you take the OMS catalog image into Photoshop, and set scale, diameter works out to about 4.5"

Or, 30 lb lift equates to 810 cu in of saltwater. Calculating with tube height of 62 in, one needs circle area of 13 sq in., which means the diameter is 4+ in.

So, I would say that it's safe to assume somewhere between the two.

To me, that's kind of a dinky SMB.
 
Don't know the exact diameter, but it's thicker than it looks on the picture.
It's very good quality, it's made out of cordura and the seems are very strong.
