High Purity Gas Regulator
The Miller Electric 200-0000 is a single stage regulator built for inert, non-corrosive gases. It connects to a pipeline supply through a 1/4 in FNPT inlet and delivers pressure up to 15 psi. A 2 1/2 in gauge and stainless steel diaphragm provide reliable monitoring and control for low pressure applications.
Single Stage Delivery Limits
Single stage regulation means outlet pressure will rise as the inlet supply drops from its maximum of 3,500 psi. The 15 psi delivery range suits processes that tolerate this variation. Brass body construction and a Sure Seat filtered seat help maintain gas purity but do not compensate for the inherent supply pressure effect.
Replaces Basic Pipeline Regulators
This unit upgrades from unfiltered or non-stainless diaphragm models where gas purity is critical. The jump is worth it when welding or analytical work demands cleaner gas streams and the 15 psi ceiling matches the process. Buyers needing higher delivery pressure or dual stage stability for constant output should look elsewhere.

Questions about this item
Should I choose the 15 psi delivery range or a higher-pressure model?
This regulator is built for a 15 psi delivery range; select it when your application requires that exact low-pressure output.
What does the 3500 psi maximum inlet pressure mean for my gas supply?
It means the regulator can safely accept supply pressures up to 3500 psi from a high-pressure source before reducing flow to the 15 psi outlet.
How does the 1/4 in FNPT connection affect installation?
Both inlet and outlet use 1/4 in FNPT threads, so you will need matching male NPT fittings to connect supply and downstream equipment.
