went to get my bottle filled for the first time and the pressure cap blew at 2lbs. the guy is bitchin that I put it together wrong but that’s difficult to do its 2 pieces that only go one way. sounds more like a defect is that likely? ---

yeah the disk is one i meant that the whole assembly is 2, the fitting the cap sits on and the cap itself. i’ll take it apart when i get it back and see if the cap blew or blew off…maybe i didn’t tighten it good enough ---

new bottle and a friend of a friend filled it. there’s no way the 800psi his refill station sits at will pop a 3k psi cap without some other problem. i’m just sick of hearing i did something wrong ---

this guy bought his own station and he’s local (got it way cheaper than that) but i will keep that in mind. and the previous statement wasnt’ directed at you you responded in between me and slowwhitez can i get just the cap or do i have to buy the whole thing now? ---

but back to my original question…is there ANYTHING that i could have fucked up putting that in that would have caused it to blow like that? not tight enough, too tight? ---

oh i think i found them [http://store.summitracing.com/partdetail.asp?autofilter=1&part=NOS-16165NOS&N=700+-150356+115&autoview=sku](http://store.summitracing.com/partdetail.asp?autofilter=1&part=NOS%2D16165NOS&N=700+%2D150356+115&autoview=sku) do you think i did anything to cause this? i can’t see it being anything but a defect…and i def am not taking it back to him as he won’t refill it, he’s convinced the blue cover for that blow off cap not being tight is what caused it. :rolleyes: yeah he said it sits at 800psi ---

i was told not to use sealant on anything. i can’t remember if i used it on those threads or not. but i can’t see how that would contribute to the disk failing ---

where was the bottle sitting before it was filled that could play a big factor in what happened and as i asked before do the station have a pressure gauge ---

yeah if the bottle was hot thats a no no freezing the bottle is a good thing and do you have the blow down adapter for your bottle if not I have one and it has the burst disk in it I’d prob. sell it for 20. [Next page](https://forums.speedlife.net/t/nitrous-pressure-cap-defect/184744.md?page=2)
