Leak on my FX Streamline

[barreira]

At which pressure shall I de-pressurize the tube through the guage?

 

[Guest]

Just loosen it about a half turn with an 11 mm open-end wrench

 

[barreira]

This information from you all as been so helpful, that I can't imagine how could I solve these problems alone in the "dark"...

 

[Guest]

Pass it on....

 

[barreira]

"Now move on to replacing the little o-ring on the valve pin. This is another one that is a pain in the butt...".

Is it really so hard to change the valve pin oring? I'm getting ansious...

And, "being there", shall I change the valve seat oring aswell?

 

[barreira]

Well, it's time to pay...

Here's some photos of my FX Streamline "surgery":

 

[Guest]

Looks great! See it's not so hard after all once you get the hang of it

If the valve seat oring looks fine i'd leave it well alone (if you have just one spare oring)

And how was the valve pin oring?

 

[Guest]

I agree there's no reason to mess with the valve seat more than likely

 

[Menttaliist]

Am i wrong or i can see a scratch on it on that last pic?

 

[barreira]

A scratch!? Where?

 

[Menttaliist]

On the valve pin oring, if i zoom it seems to be a bite on it, right on the midle

Congratulation Mentalist you just found the man's slow air leak! Good looking out bro

 

[barreira]

Here?

 

[Menttaliist]

Yeah right there

 

[barreira]

Valve pin oring changed.

Air getting out from here now:

 

[Guest]

Ok that means one of the orings on the regulator is not making a good seal, just replace both of them and you should be good to go!

 

[barreira]

After orings changed filled the FX:

After one night it's loosing air, and the same slow leak:

 

[barreira]

FX Support told me that the problem might be in the valve seat and that is quite hard to remove it from inside the breech.

That pics right there could be the air just settling down on the air tank and decreasing it's temperature after fill. A small drop on pressure like that isn't a sign of anything. What till you see a bigger difference and if there isn't your problem is fixed.
