Matheson Model 8 dual-stage regulator, solenoid, Swagelok metering valve. All new and unused components. Can hook up to CO2 tank to test before sending if you want me to. Will install 1/8" NPT adapter on metering valve if you want for use with JBJ type bubble counter, or will include a brass insert to hook up 1/4" OD x 3/16" ID tubing directly to metering valve for use with inline bubble counter.
