0781-1450 - Victor SR4J-680 High Pressure Inert Gas Piston Regulator, 3000 PSIG Delivery

Heavy-Duty Performance for High Pressure Testing

For welders, fabricators, and testing technicians requiring reliable high-pressure gas control, the Victor SR4J-680 Inert Gas Regulator stands out as a top-tier solution. When you are conducting pressure vessel testing or dead-end testing, you need equipment that won't back down under stress. This regulator is built to deliver massive pressure—up to 3000 PSIG—safely and consistently. The SR4J-680 is not your average shop regulator; it is a heavy-duty piston regulator designed to handle the extreme conditions that would damage standard diaphragm units.

Durability is at the core of the SR4J-680's design. The entire body and housing cap are machined from solid brass, ensuring it can withstand the knocks and bumps of a busy industrial site while containing inlet pressures as high as 5500 PSIG. One of the standout features for daily use is the Delrin cap bushing. This component ensures that when you dial in your pressure, the adjustment is smooth and responsive, not jerky or stiff. This allows for precise control when you are stepping up pressure during critical testing procedures.

The regulator connects via a CGA 680 fitting, which is the standard for high-pressure inert gas cylinders, ensuring you have the correct and safe connection for your gas supply. The outlet is fitted with a 1/4-inch Swagelok connection and stainless steel tube fitting, providing a professional, leak-proof hookup for your hoses or hard lines. With large, easy-to-read 2.5-inch brass gauges, monitoring your supply and output is effortless. Whether you are pressurizing a tank for a hydro-test or managing high-pressure inert gas flows, the Victor SR4J-680 gives you the confidence and control you need to get the job done safely.
