NAKAO Nitrogen Regulator 0-600 PSI | CGA580 Inlet | 1/4-in Flare Outlet | Heavy-Duty Brass

Precision pressure control for inert gas tasks

The NAKAO Nitrogen Regulator combines compact, rugged design with reliable materials to help you manage tank pressure with confidence. Built for routine gas handling, it supports a range of tasks from HVAC purging to brazing and soldering, with an emphasis on steady readings and smooth operation in busy environments.

Clear gauges for quick readings

Two large gauges make it easy to monitor pressure at a glance. The cylinder gauge reads up to 4000 PSI with a max input around 3000 PSI, while the output gauge covers 0-600 PSI and is designed for practical use with a 500 PSI operating range and a 600 PSI safety limit. The gauges are protected by a scratch-resistant cover and a rubber sleeve to help prevent glare and damage during work.

• Cylinder gauge: 0-4000 PSI; max input approx. 3000 PSI
• Output gauge: 0-600 PSI; typical working pressure near 500 PSI, 600 PSI safety limit

Versatile connections for common gas setups

The regulator uses a CGA-580 inlet and a 1/4" SAE male flare outlet, enabling compatibility with nitrogen, argon, helium, and other inert gases. This combination supports straightforward installation and dependable sealing on standard cylinders.

• Inlet: CGA-580; fits standard cylinders for inert gas applications
• Outlet: 1/4" SAE male flare; 7/16-20 threads for secure, leak-free connections

Durable design with thoughtful features

Made from solid brass, the regulator uses a robust piston-diaphragm arrangement and a large brass T-handle with a stainless steel adjustment screw. A self-reseating relief valve adds a safety layer during operation, while the overall build prioritizes reliability in demanding shop settings. Note that it is designed for general pressure control and is not a substitute for downstream protection systems.
