Brass adapters for matching acetylene cylinder valves and regulator inlets.
Available combinations cover CGA-200, CGA-300, CGA-510 and CGA-520; choose the exact direction required.
The first CGA number identifies the cylinder valve; the second identifies the regulator inlet. For example, CGA-200 to CGA-520 connects a CGA-200 cylinder to a CGA-520 regulator.
Verify both CGA markings and dimensions, and use only with equipment approved for the gas service.
