What fitting do I need to remove a gas sample from an NPT outlet (such as from a regulator) with a syringe?
For a 1/8? NPT outlet, use male connector cat.# 21941 (for a stainless steel fitting) or cat.# 21841 (for a brass fitting) and a Shimadzu plug. For a 1/4? NPT outlet, use male connector cat.# 21942 (for a stainless steel fitting) or cat.# 21842 (for a brass fitting) and a 9.5-10mm septum.
