S.120M Oxygen Pressure Regulator
Date of manufacture:
This regulator is the BOC S120M, capable of delivering a pressure that may be adjusted up to 8 bar. The standard oxygen therapy pressure at the the time of production was 4 bar and it would have typically been connected to an oxygen therapy flowmeter/ needle valve assembly. This adjustable regulator is equipped with a cylinder contents pressure gauge, marked 'oxygen' and registering up to 300 bar. There is no gauge registering the regulated pressure. Furthermore, the bullnose cylinder connector is capable of being connected to any non-fuel gas cylinder including those that are not medical gases. The screw thread gas outlet gives no hint of its intended purpose.
