RX WELD Nitrogen Regulator with 0-600 PSI Display, CGA580 Inlet, 1/4-Inch Flare Outlet, 5ft Hose

Your workflow deserves a regulator that combines reliable performance with practical ergonomics. The RX WELD Nitrogen Regulator is built around a brass body with protective gauge boots for visibility in busy shop spaces. It accepts a CGA580 inlet and a 1/4-inch SAE flair outlet, making connections straightforward with common nitrogen tanks and lines. The compact footprint and smoothly surfaced knobs are designed for comfortable handling even when wearing gloves. With the included 5-foot refrigeration hose, you can position the unit where it’s most convenient without stretching hoses or twisting fittings.

Two large 2-inch gauges sit at a comfortable viewing angle. The left gauge shows source pressure, while the right gauge indicates adjustable output, letting you dial in the flow you need for purge sequences or pressure tests. The regulator handles a broad input range up to 4000 PSI and an adjustable output from 0 to 450 PSI. The display is capable of indicating up to 600 PSI, which provides a useful safety margin when you rate your setup. Keep in mind the rated output target is 450 PSI, even though the display can reflect higher values.

Engineering details emphasize durability and precision. A sturdy brass tee handle, stainless steel pressure adjusting screw, and a regulator bushing help prevent galling and wear through repeated use. The brass piston-based diaphragm delivers stable performance, while a self-seating relief valve adds an extra layer of protection for the regulator itself. Note that the valve is not designed to protect downstream equipment, so operators should plan the workflow accordingly. This combination of components supports reliable control during purge or inerting tasks and reduces the need to swap gear mid-project. The 5-foot hose adds flexible positioning so you can work with comfort and efficiency.

Key benefits

• Secure connectivity with CGA580 inlet and 1/4-inch flare outlet for compatible nitrogen systems
• Clear readouts from two large gauges with rugged protective boots
• Wide input and adjustable output (0-450 PSI) for diverse tasks
• Gauge display up to 600 PSI for safe monitoring during setup
• Durable brass construction and anti galling design on the adjustment assembly
• Long 5-foot refrigeration hose for flexible placement
• Ergonomic controls including a large tee handle and stainless steel screw
• Safety note: the built-in relief valve is not intended to protect downstream equipment

Ideal uses

• HVAC purging and inertization to reduce contamination during testing or brazing
• Leakage testing and pressure verification to confirm system integrity
