591IN-750 - Gentec 591 Series High Pressure Piston Regulator, CGA 580, 750 PSI Delivery

Reliable High-Pressure Control for Inert Gases

The Gentec 591IN-750 is a robust high-pressure regulator designed to meet the rigorous demands of industrial and HVAC applications. When you need to deliver high pressure from an inert gas cylinder—whether it is Nitrogen, Argon, or Helium—this regulator provides the control and durability required for the job. Unlike standard welding regulators that typically top out at lower pressures, this unit is engineered to deliver up to 750 PSIG, making it an essential tool for pressure testing piping systems, purging AC lines, or charging industrial accumulators.

Built with a piston-type mechanism, this regulator offers superior durability compared to diaphragm-style counterparts when operating at high delivery pressures. The piston design is less prone to failure under high stress, ensuring a longer service life and consistent performance in the field. The body is machined from high-quality Class "A" brass bar stock, providing a solid, rugged construction that withstands the wear and tear of daily use on job sites.

Safety and longevity are built into every aspect of the design. A sintered bronze inlet filter is integrated to trap dust and impurities before they can enter the regulator, protecting the internal seating mechanism from damage. Additionally, the unit features an internal safety pressure relief valve to prevent over-pressurization. The large 2-1/2 inch gauges are easy to read, allowing operators to monitor both cylinder volume and delivery pressure at a glance. Whether you are a contractor performing leak tests or a technician managing industrial gas systems, this regulator delivers the precision and power you need.
