High-Purity Regulator for Inert Gases

The Miller-Smith Equipment 213-4109 is a single-stage regulator built for argon, helium, nitrogen and other inert gases. It connects to a cylinder through a CGA-580 inlet and delivers pressure from 0 to 150 psi. The brass body and stainless-steel diaphragm suit laboratory and welding supply use.

Thermal Behaviour and Pressure Integrity

As a mechanical pressure-control device it produces no operational noise and draws no electrical power. The stainless-steel diaphragm and Sure Seat filtered seat maintain consistent delivery pressure up to the 150 psi limit. Maximum inlet pressure is rated at 3,500 psi while the supply gauge reads to 4,000 psi.

Included Components and Practical Effect

The unit ships with a bonnet, gauges and a plated brass body finished at 2.0 in diameter. A 1/8 in brass tube fitting provides the outlet connection. These factory-fitted parts mean the regulator is ready for cylinder connection without additional fittings.

Questions about this item

How do I install the CGA-580 inlet connection on a cylinder and which step is often missed?

Thread the CGA-580 nut onto the cylinder valve, tighten with a wrench, then open the valve slowly; the step often missed is purging the line before setting the delivery pressure.

What maintenance will the stainless steel diaphragm and Sure Seat filtered seat need later?

Inspect the diaphragm for cracks and the filtered seat for contamination annually; replace either part if leakage or pressure drift appears.

At what supply pressure does the 3,500 psi max inlet limit become the first constraint under sustained use?

The 3,500 psi max inlet pressure is the limiting factor; do not connect cylinders exceeding this rating.
