NOS Nitrous bottle blow down fitting
http://www.nitrousoutlet.com/catalog...9&product=2550
then the blow out side uses an 8an fitting
burst disc goes between the bottle and the fitting
follow direction.. torque to 15 ft-lbs
over torquing will damage burst disc and make it blow off at a much earlier pressure(like a couple of hundred psi instead of a couple of thousand psi..)
