ive been having problems hooking up my nitrous system..everything seems to work fine butwhere the bottle nut connects to the bottle leaks.. and idk why.. i purchased one of those copper bottle nut seal things.. that you need and have it in andi tighten it pretty tight but still leaking.. what am i doing wrong?

 

anybody have anything to help?? people running nitrous are you even running a washer inbetween the bottle nut and the bottle???

 

There is a teflon washer in between the valve and nut on my NOS brand nitrous bottle. (all 3 i have owned had it) Never seen a copper one personally.

This part is what you need
