Single-stage nitrogen regulator
This single-stage regulator from Miller-Smith Equipment is built for nitrogen cylinders with a CGA-580 inlet and delivers outlet pressure up to 450 psi. It suits HVAC technicians and welders who need a compact brass body with a 2 in gauge for clear supply and delivery readings.
Verify cylinder and outlet match
Confirm your nitrogen cylinder uses a CGA-580 valve before ordering. The regulator outlet is a 7/16 in -20 flared fitting, so ensure your hose or manifold accepts that thread. Maximum inlet pressure is rated at 3,500 psi, and the supply gauge reads to 4,000 psi.
Brass body with neoprene diaphragm
The 2.0 in diameter brass body houses a neoprene diaphragm and includes a nylon adjustment knob for smooth control. UL listing confirms the unit meets recognised safety standards for gas regulation. This model is not suited for high-flow industrial manifolds or applications requiring dual-stage pressure stability.

Questions about this item
Does the regulator ship with a hose or torch, or do I need to buy them separately?
The unit includes a nylon knob only; hose, torch and any fittings for the 7/16 in.-20 flared outlet must be purchased separately.
Should I choose the 450 psi model or a different delivery-pressure version for nitrogen HVAC work?
Select the 450 psi version when your HVAC nitrogen procedures call for a 450 psi delivery range; other pressure ranges are different models.
What does the 450 psi delivery range mean when the regulator is connected to a nitrogen cylinder?
It means the outlet pressure can be adjusted up to 450 psi while the inlet gauge reads up to 4,000 psi from the cylinder.
