591N-1500-680 - Gentec 591N High Pressure Piston Regulator, CGA-680, 1500 PSI Delivery

Heavy-Duty Power for Pressure Testing

When your job requires more than just standard shielding gas flow, the Gentec 591N-1500-680 steps up to the plate. This isn't your average flowmeter; it is a high-pressure beast designed for welders, pipefitters, and HVAC technicians who need to perform serious pressure testing or system purging. With a delivery capacity of up to 1500 PSI, this regulator allows you to push Nitrogen, Argon, or Helium into systems to verify integrity before you lay a single bead or charge a system. The CGA-680 connection is specifically designed for high-pressure tanks, ensuring you can hook up to the heavy-duty cylinders required for intensive site work.

We know that gear on a job site takes a beating. That’s why the 591N series ditches the fragile rubber diaphragm found in light-duty regulators and replaces it with a solid brass piston. This piston design can handle the shock of opening a high-pressure valve without blowing out, giving you peace of mind every time you crack the cylinder. The solid brass body is machined, not cast, meaning it can survive the knocks, drops, and drags that happen in the back of a truck or on a busy fabrication floor. The gauges are housed in steel cases, adding another layer of protection against accidental impact.

Whether you are purging a long run of stainless pipe with Argon, pressure testing a new HVAC installation with Nitrogen, or charging shock absorbers, precision and safety are key. The Gentec 591N gives you smooth, controlled pressure adjustment thanks to its low-friction Delrin bushing. Don't risk your safety or your reputation with undersized equipment. Equip your rig with a regulator that matches the pressure of your work. The 591N-1500-680 is built to perform when the pressure is on.
