Have a picture to confirm? It's the one that gets crushed or messed up if you install the grip incorrectly or on a bad angle.

Hi Puma it seems like I need to put a lot of force to get the thing in there and I am on my second set of o-rings I am shure that I am doing something wrong LOL

Not sure if those are the same size as the o-ring size posted. Anyone confirm?

This is what I believe the 006 o-ring is for:

I think that’s it Puma the one on the Flow Connector Bolt is small but thin walled I tried some that fit but where to thick and they just pinch going in and brake so we know 006 will not work on the Flow Connector Bolt

Cool! Anyone know the different type of material used?
For example: the A5 has black, clear, clear/white, and grey o-rings

I have been searching lately for the smaller O-rings that go on the RT flow connector bolt and it seems they are special order and are very hard to find, so I had to contact tippmann for some and they just sent me a whole new flow connector bolt. I did however find a place after searching around town for a few days that has the tiny ones, the place was called seal source.

I had the same problem ended up just searching the yellow pages in my area for a pneumatics place and they had all the stuff I needed. Hydraulics places usually work to.
