NITROUS OXIDE ( nos / n2o ) advice forum

Hi
I've had two pipes come out of olives. I've added a DP to my single point kit over winter. Just got round to testing after getting other things done to car.
Was checking for leaks and as I tightened a nut on a seeping pipe and when I recharged the lines the pipe popped out. I don't think I could have tightened it up any more so don't think it was loose.
Then tried system on way to japfest on Sunday and things weren't working so turned power off to kit, but left bottle open, just forgot to turn it off. Decided to give it a quick check before I set off home, to see if I could get it working for way back. I noticed there was no pressure to gauge. Checked pipes and another pipe had come out. So lost a full 11lb bottle of nos
I had checked all pipes and nuts and know nothing was lose.
Anyone any ideas what the problem could be? Is it likely to be just the olives or could it be the pipes?
Starting to wish I had stayed single point as never had any real problem with that.

Hi trev.

I got a full second hand Dp kit from you back around the start of November.
One pipe has come out of a Y block and the other from a T piece. Looks like the olives have only compressed down on one side.

Think I could have a spare olive and nut to try and reseal. What's best way to check that it is on secure?

Cheers

The Y block is right at the bottle where I split to two lines. The other that came out is a T piece half way down on leg that feeds my gauge.

Just bin out and checked them over, had 3 pull off. Was hard to see the difference in the tapped edge. The one that had popped out, was the easiest to see the problem. There is just a hole, no tapered edge at all. Don't know how I never noticed when I fitted it, as hole looks a lot bigger than the pipe. Don't know how it had sealed at all.

Have replaced them with spares I had. They seam to be holding better. Will have to wait and see how things go once I get the bottle filled.

Sorry about the photos but best I could get on the iPhone.

3 of them look fine and the 4th one looks like it's been drilled out. My guess is that the nuts we supplied were also from our used stock and one must have been used as a special and drilled out for that.

They certainly don't look like the ones I first mentioned.

Yes I couldn't see any diffrance with 3 of them. But they did pull off, maybe they were still a bit lose. But I had bin round to tighten them all up the other day. Not sure if I could have got it any tighter. But it is a bit of a pain to hold the Y block while tightening the nut.

Will see how it is once I've got my bottle filled. Probably going to be a few weeks though.
