Default Nitrous Leak

Ok so I've finally got my bottle and everything up and running. I thought i finally had all the leaks sorted out but I closed the bottle last night with 800psi still in the line and this morning. 0psi. So I've obviouslly still got a small leak somewhere (don't get me started on NPT fittings. Worste sealing POS I've ever dealt with)

Wondering if anyone has tips on how to find the small leaks. I can't hear anything. Any sort of liquid i could coat the fittings etc in to look for the leak?

Wasting most of my bottle on leaks. And while im on that topic guys in the US need to stop complaining about there $37 10lbs bottle fills. Cheapest you get Nitrous in Alberta, Canada is $8.50 per lbs.

dish soap and water, spray your lines and fittings down and if you see bubbles there's your culprit!...i had to do the same thing....

I thought it was a given that nitrous would slowly leak out of the ss lines overnight, thats why you keep your bottle closed and why you purge. How are your solenoid problems btw?

I don't see how.. The solenoid is shut. Shouldn't the nitrous pressure hold in the lines?

If i'm wrong please someone correct me so I don't go looking for an invisible leak.

Also solenoids are all good thanks man. It was actually my DynoTune window switch. I had it wired thinking the Output was 12V when it was actually a ground. So the solenoids weren't getting anything.

You probably could expect to loose some pressure but if your PSI is 0 then i would have to say leek.

Look on the bright side, you dont have fuel leek (that was fun).

HAHA then you know how ****ING awful those can be.

Hows the DynoTune window switch working out for you? I never got mine running hints the reason I ended up selling the kit.

I actually preffered the fuel leak over the nitrous leaks. But neither are fun.

The window switch is great not I got it working. I initially thought the outputs where 12V when in fact they are grounds so things weren't working too well. Got that fixed and no issues.

u have to purge the lines out after u close the bottle cause u wear the seals in the solonoid. and u probably lose a lil no2 if u leave it in the lines over night

Don't leave pressure in the lines when not in use.
It will weaken the seals. And from what I understand, the design of some solenoids don't use rubber seals, they use a metal cone design that sets into a metal valley to create a high pressure seal.
<<
But this type of seal will slowly leak, and with less pressure (such as a bottle closed), will cause it to leak faster as the pressure goes down since the pressure creates the seal.

Nice explanation.

Definitely use the dishwasher soap diluted in water sprayed onto the nitrous lines to find the leak.

I have a very small leak as well, right where the line meets the nitrous solenoid. Personally, this used to bother me a lot, but I no longer care anymore. I don't lose pressure in the lines unless I leave it like that for long, and I don't do that anyway (always purge to 000 if there's any pressure in the nitrous lines). This is my 2nd solenoid from Dynotune so I guess it's just how they're manufactured. If it's a very slow and tiny leak, just forget about it. I've tried using liquid teflon (the nitrous pressure will push that out) and loc-tite (won't seal properly or blow it out). I ended up using layers of teflon tape (frowned upon for nitrous use), but I haven't had trouble with it and it pretty much stopped the leak to an almost unnoticeable one.

I would just take out the fitting, clean it, and put fresh telfon paste and make sure it is on properly and check again.

It depends on the fitment of the line to the solenoid. Certain fittings won't be as tight as you might like it to be and teflon paste won't cut it. That's how my nitrous solenoid was and I ended up using copious amount of teflon tape (generally not recommended for nitrous) but that stopped it enough to where the leak was almost not noticeable.

well tomorrow im going to try the paste and tighten it again and then see how it looks...hopefully it stops because im pretty sure it would be bad if i was driving around and had gas leaking under my hood right by the solenoid right?

I don't think it'd be THAT bad, but it is definitely a safety hazard for sure.

Sucks it's leaking, you should be able to get a nice high off of it atleast.
