Beaiguna Nitrogen Regulator – HVAC 0-600 PSI, CGA580 Inlet, 1/4 inch SAE Flare Outlet for Purging, Leak Testing, Welding

Beaiguna Nitrogen Regulator

Designed for HVAC pros and serious DIYers, the Beaiguna Nitrogen Regulator combines precision, durability, and versatility in one compact tool. It accepts up to 3,000 PSI input and provides a finely adjustable output from 0 to 600 PSI, enabling controlled nitrogen flow across a range of tasks from line purging to welding prep. The dual gauges are clearly marked for quick reference, and they are protected by a rugged rubber boot to withstand the demands of busy work sites. A built-in relief valve helps prevent over-pressurization near the upper end of the scale, giving you an added layer of safety without slowing you down.
