The connection type ensures compatibility with your gas cylinders and downstream equipment. Welding gas regulators offer a range of inlet connections (CGA 320, 540, 580, 347, 350, 346) and outlet sizes (such as 1/4" NPT, 5/8" - 18 RH, 9/16" - 18 RH). For example, the Harris 9296-50-320 features a CGA 320 inlet for CO2 and a 5/8" outlet, while the Harris HP8700-4500-347 uses CGA 347 for high-pressure air. Multiple connection options ensure you can find a welding gas regulator compatible with your specific gas supply and application.
