Siasky Nitrogen Regulator: Precision for HVAC Pressure Testing

The Siasky Nitrogen Regulator is built for HVAC professionals who demand reliable control during pressure testing and leak checks. With a robust brass body, a wide 78.7" hose, and precise gauges, this regulator supports accurate feedback as you verify system integrity in AC units and other HVAC components.

Key specifications at a glance

• Delivery pressure range: 0–800 PSI
• Low-pressure gauge: 0–800 PSI
• High-pressure gauge: 0–4000 PSI
• Hose length: 78.7 inches for usable reach
• Inlet: Brass CGA580 for secure nitrogen connections
• Outlet: 1/4-inch male flare for versatile fittings

The gauge range and dual-display design help you monitor changes in pressure with clarity, while the enduring brass construction is designed to stand up to frequent field use. It’s a practical addition to any service cart when you’re testing, testing, and retesting HVAC systems for leaks and performance.

Field-ready performance and compatibility

• 78.7" hose offers ample movement around coils and components
• CGA580 inlet ensures a secure fit with nitrogen tanks
• 1/4" male flare outlet supports a range of compatible connectors
