Help me find this part.

Didn't there used to be a part that allowed you to keep the bottle closed but still read pressure on the gauge so that you could safely monitor bottle temp?

there are bottle valves the have the guage on the valve that read closed. nx and nos sell them. i am pretty sure they first came on NOS carbon fiber bottles

Cool, thanks. I'll look into it.

Nos Super High Flow valve is what you want

NX sells a new 45 degree valve with two ports in the side.It sells for around 95.00.
