The outlet connection size/type ensures compatibility with hoses and equipment. The most common sizes for an argon regulator are 5/8 in. - 18 RH (used in Harris 3500-200-580 and Harris 9200-250-580), and 9/16 in. - 18 RH (seen in Harris 425-200-580). Specialized models like the Harris HP8700-2500-580 use a 1/4 in. NPT with a stainless steel tube fitting for high-pressure or lab applications. Selecting the right outlet type ensures easy integration and safe operation. Multiple sizes and types are available to match various setups.
