The pigtail is 1/4" 316 stainless steel tubing, having 10 coiled turns (exceeding 36" in length) with equal distance between the coils to mitigate thermal coupling of the coils. Inlet is 1/4" NPT female pipe and the outlet valve has a restriction orifice isolating the Joule-Thompson cooling effect during cylinder purging. Pressure tested to 2200 PSI.
