Wocketman,
How do you install a piece of brass tubing into a Festo fitting without leaking?

Lessee here: Festo 6 MM fitting=.2362 I.D.
7/32 brass tubing=.2188 O.D.
difference= - .0174 too small

Sounds like 7/32"is too small, and a 1/4" (.250 O.D.) tube is too big.
The 7/32" brass tubing will NOT seal on the "funnel shaped sealing ramp" inside the Festo fitting. I just tried it, and under suction or pressure it leaks like a seive.


Please explain to us how you manage to use hard tubing in a Festo fitting (designed to use soft tubing) without leaks.

Since my jets are more valuable than an improperly used Festo fitting, I think I will stick to the time honored methods I described in an earlier post.
No flame war intended.
