RX WELD Nitrogen Regulator 0-4000 PSI Input, 0-600 PSI Output, CGA580, 60-Inch Refrigeration Hose

Meet the RX WELD Nitrogen Regulator, a compact brass-built solution engineered for dependable gas control in HVAC, brazing, soldering, and leak-testing workflows. Thoughtful details—like protective gauge boots and a sturdy brass body—are designed to stand up to daily shop use while delivering steady, controllable pressure as you set up your process.

Key specifications at a glance

• CGA580 inlet connection for secure, compatible gas attachment
• Output adjustable from 0 to 600 PSI, with a display capable of showing up to 800 PSI during setup
• Input range up to 0–4000 PSI, enabling diverse gas cylinders and supply scenarios
• 60-inch refrigeration hose with 1/4" female flare connections for flexible reach
• Protective rubber gauge boots to help shield the gauges in busy work environments
• Large brass tee handle and stainless steel pressure adjusting screw, plus rugged regulator bushing to minimize galling
• Self-reseating relief valve (note: not designed to protect downstream systems)

The display and control layout are designed for straightforward operation, so you can dial in the right pressure for each task without guesswork. The long hose provides freedom of movement around components and assemblies, reducing the need to reposition equipment constantly.

Common applications and practical uses

• HVAC purging and inertization tasks where clean, controlled gas flow matters
• Pressure and leakage tests during installation or service work
• Brazing and soldering operations where steady gas pressure supports clean joints
• General gas line testing and setup procedures that benefit from a wide input range

In real-world use, the regulator’s brass construction provides durability, while the 60-inch hose helps you keep lines organized and away from heat sources or sharp edges. Use the gauge readouts to monitor pressure as you configure the system, then fine-tune output to suit the task at hand. Remember the relief valve is a self-seating feature intended for nuisance protection rather than downstream system protection, so plan your workflow accordingly and follow standard safety practices.

Why choose RX WELD for your shop

With a focus on reliable, repeatable performance, the RX WELD regulator is designed to be a practical partner in learning environments, service bays, and field setups. The combination of a robust brass body, accessible adjustment mechanism, and long, flexible hose supports a range of tasks without requiring frequent part changes. While it offers substantial capability, it’s best viewed as a versatile tool to assist you in achieving controlled gas flow rather than a guarantees-for-every-scenario solution.
