System X 3 way

[Seajay]

So I'm rebuilding a System X I think Vengeance 2.0 cocker and I've actually got it functioning after rebuilding a lot of parts.
I can't figure out the correct 0-rings for the 3 way though.

They look to be 006 but they don't seal as is. 007 are too big. A wrap of tef tape and the 006 o-rings "Work "... but it's very temperamental and leaky with a jiggle.
It's a 3 o-ring spool and the 3 way body itself is just a smooth tube. You use the spool to adjust and thread onto the arm.

I've used 006 on System X (and Dye) cockers before, as that is supposed to be the correct size. Maybe the o-rings you're using are just a bit undersized, and/or maybe the bore of the 3/4 way is slightly oversized. I'd just use the teflon/ptfe tape fix personally. Maybe wrap it just a bit thicker if it gives you trouble.

Thanks. I'll tweak it a bit more then. I'll try some dow 55 too see if that might get the o-rings to seal a little better.
