Harbor Freight has them for very inexpensive. Buy the assorted pack of 300 for $7. They work great on my Hatsan PCPs.

I found that the SAE ones were closer to the OEM ones on the barrel. They have been holding up great in my Pneuma. Shots are consistent and she groups under 3/4 inch at 5O yards.
I have bought about every o-ring kit that H.F. has & very few fit anything, standard or metric. The parts list for your gun has all the o-ring sizes listed so you can order each as necessary. I bought O-rings for my AT44 off of Ebay, the only problem is I had to by a pack of 20, but they were only about $6 w/shipping. These are the ones I bought for the AT44 where the valve & fill adapter screw into the air tube, http://www.ebay.com/itm/160787186969?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 The same Co. has about every size you need. I would think that Umarex would charge you more than that for just one.
