Acetylene Cylinder To Regulator Adapters For Cga 200 And Cga 300

CGA-200 is found in MC tanks. CGA-520 is found in B tanks. CGA-510 is found in almost all larger Acetylene and Propane tanks. CGA-300 is also used in larger Acetylene tanks but is less common. Adapters are needed when the mating threads of the cylinder valve and regulator do not allow for a direct connection.
