Retro valve with level 7

[jpm]

I'm putting together a marker from spare parts. Got the thing all together and gased it up no problems fired it a few time and the power tube oring shot out. So when I got a new oring and put it back in the tip I noticed the space was loose between the power tube tip and the oring in the bottom. It's been a while since I worked with a level 7 bolt but I don't remember the spacer rattling in the tube. I looked at the parts blow up of the valve and it doesn't look like I'm missing anything. Can someone please advise as to what might be going wrong or happens point out something I might be missing.


Thanks,

Is your spacer a stock spacer or is it from a aftermarket kit? It sounds as if your spacer is too short. AGD used to make a spacer kit although I am not too sure if they still do. And pro team products used to make one too and I am not sure if they make it either.

I found the issue. The Reg seat O-ring and the Power Tube O-Ring and shorta similar in size and my pack of O-rings had 5 Reg Seat O-rings and only 1 On/Off - Powertube O-ring left. I was just having a hard time identifying the right O-Ring. Once I got the right o-ring in there it was rather obvious that it was the correct one. Thanks for the reply AGDFlash.
