Name: Fisher&#8482; Type R222 Series Second-Stage Regulators
Brand: Fisher

R222 Series is an Underwriters Laboratories listed regulator designed for Two-Stage LP-Gas systems.

The unit is designed to reduce the outlet pressure from a first-stage regulator (usually 10 psig / 0.69 bar) to an outlet pressure of 11-inches w.c. / 27 mbar. The unit?s compact size makes it ideal for tight fit applications. A screened drip-lip vent is oriented over the inlet in the standard configuration. Fisher second-stage regulators are painted palm green for easy identification.
