Captured Vent
The captured vent design is for maximum safety for the user when handling toxic or hazardous media. It
features a 1/8" FNPT port located on the spring housing. The user can easily tube this vent to a safe location.
Panel Mount
The panel mount feature requires a panel cut out of 1-1/2" allowing insertion of the threaded spring hous-
ing, and a panel mount ring to secure the regulator against the panel.
