Recently got a new to me classic valve with lvl7. I replaced orings and lubed it. Runs great. Swapped in a rt on/off and it leaks down barrel unless you pull trigger indicating issue in power tube. Nonissue though again with the am/mm on/off. Got me but puzzled.

From what I nerstand, the classic valve cant use the rt on/off -
They can... but there won't be any RT effect. It does reduce the trigger pull by half though. I used one with my EPneumag and it was fantastic.Originally posted by BrickHaus View Post
Tinybear - have you changed all the orings in the on-off? I know it seems to be a powertube problem, and maybe a different spacer will help, but it seems odd that swapping an on-off would repair the leak.Comment

Yes it’s a brand new rt on/off new orings and with the factory .750 pin. Replaced every o ring as this valve was pretty much new but all the orings were dried up.
Going have to go on back burner it seems as I all outa air. Not sure where I can get fills till things start opening back up again. Swapped back in the original on/off for now. Once I get air I may try the RT on/off in my other classic valve. And see if the leak follows to the other valve.
I unfortunately don’t have any power tube spacers either.AGD 68 Automag, AGD ULE 68 Automag, Azodin KPII, Tippmann SL68II, Umarex TR50.Comment

I remember doing this with my mag I had long ago. If I recall correctly I had to use a different outer O ring to properly seal it. Can't remember what size though...Comment

Tinybear I sent you a message but I'm not sure it got sent because I can't find it anywhere. Did you ever get this sorted out? I am having the exact same issue trying to get a rt on/off to work in my classic minimag valve.Comment

Make sure you have your rail bushing in place. No-bushing lets the valve body shift backwards, allowing the power tube to leak.
Otherwise, the RT on/off works well in the classic for a lighter trigger pull.Comment
