Purpose & User
The Miller-Smith Equipment 210-4109 is a single-stage high-purity gas regulator designed for laboratory use with argon, helium, nitrogen and other inert gases. It delivers a controlled outlet pressure range of 0 to 15 psi from cylinders fitted with a CGA-580 inlet connection.
Installation Notes
The brass body features a CGA-580 nut for direct cylinder attachment and a 1/8 inch brass tube fitting on the outlet side. A 2 1/2 inch supply pressure gauge reads up to 4,000 psi while the maximum inlet pressure rating is 3,500 psi. The stainless steel diaphragm and Sure Seat filtered seat help maintain gas purity during operation. Ensure the cylinder valve and regulator threads are clean and undamaged before tightening to avoid leaks or contamination.
Suitability
This regulator suits technicians and labs needing precise low-pressure delivery of inert gases from standard high-pressure cylinders. It is not intended for flammable, oxidising or corrosive gas services. Buyers who require higher delivery pressures, multi-stage regulation or different inlet connections should look at alternative models.

Questions about this item
How do I confirm the regulator is delivering the correct pressure after connecting it to a cylinder?
Open the cylinder valve slowly and watch the 2 1/2 inch supply pressure gauge rise to the cylinder pressure up to 3,500 psi; then adjust the knob until the delivery gauge reads the desired value between 0 and 15 psi for Argon, Helium or Nitrogen.
Which fittings and accessories come with the 210-4109 and what must I supply myself?
The unit includes the bonnet, gauges, plated brass body and Sure Seat filtered seat with a CGA-580 inlet nut and a 1/8 inch brass tube outlet fitting; you must provide the gas cylinder, appropriate tubing for the 1/8 inch outlet and any downstream flow control device.
When should I choose the 0-15 psi delivery range version instead of a higher range model?
Select this 0 to 15 psi version when your application requires low-pressure delivery of Argon, Helium or Nitrogen such as laboratory or precision welding tasks; higher range models are intended for different pressure requirements not covered by this regulator.
