Air leaking from reg grub screws

[WildWayz]

Hi guys

I had about 2500psi left in my bottle, so I thought i'd dry fire the rest out to help break my Mini's spring in.

When it got to about 500psi, I noticed a hissing from the bottle's Ninja reg. Air was coming out of both grub screws and the reg was extremely cold!

Is this normal? Or have I somehow killed something?

It was used at YPC at the weekend with no issues (put 4000 balls through it)

Cheers!

SOME regs can behave strangely when you get below their preset value, when you next fill put about 1000psi in it and see if it holds air. Fire the marker a bit to see that the reg is ok, if all is fine fill it up.

Is the bonnet screwed down properly?

Normally with Ninja regs you get a small screw in 'lever,' remove the grub screws, screw in the 'lever' all the way then back out a turn and then use this to mak esure the bonnet is properly seated and screwed all the way down.

Remove the 'lever' a replace the grub screws making sure they are tight but not over tightened.

Of coursemake sure the bottle is empty and if you don't know what you're doing, LEAVE IT!

Thanks Tom - will give that a go. Bummer is, the next event I am going to is District 10 - would be a bummer if the reg was dead :/ I guess BZ will be there, and if so they should swap it out... will call them on Monday to get their advice.

Rich - not gonna fiddle with it - last thing I want to do is do something half arsed and risk myself or other's lifes over something like this!

Don't worry about it when both of my ninja regs get a fair bit below 500 they leak air sometimes. Thinking about it now that they seemed to do it when they were new. Maybe the orings bed in the more it gets used so they stop leaking.

I had exactly the same issue with my Ninja reg when I dumped the contents of a bottle quickly and froze it down - I think it was the large o-ring that seals the bonnet freezing and letting air past. Leak vanished once the reg had warmed up again and I've not had it since.

Thanks - puts my mind at rest
Kinda thought it would be something simple. Will do as advised and fill it to 1000PSI and see how it performs before fully filling it.
