Nitrogen Pressure Regulator 0-600PSI CGA580 Inlet 1/4" Flare Output

The SPARC Nitrogen Pressure Regulator (CGA-580) delivers precision, durability, and reliability for HVAC, welding, and inert gas applications. Built from solid brass and engineered for accurate pressure control, it provides smooth delivery from 0–600 PSI and accepts up to 3,000 PSI input pressure. Whether you’re purging HVAC lines, pressure testing, brazing, or filling tires and shocks, this full-size regulator ensures consistent performance every time. Designed for universal compatibility, the CGA-580 inlet connects seamlessly to Nitrogen, Argon, Helium, and other inert gas cylinders, while the ¼" SAE male flare outlet (7/16"-20 threads) fits standard HVAC hoses and gauges. Large 2" gauges with rubber guards provide clear, PSI-only readings without clutter, and a self-reseating relief valve offers added safety. Backed by the SPARC Lifetime USA Warranty and supported by our Denver-based customer service team, this regulator is built to work as hard as you do.
