223-4008 - Miller Smith Silverline 220 Series High Purity Oxygen Regulator CGA 540

Reliable Two-Stage Performance

For professionals demanding the highest quality in gas regulation, the Miller Smith 223-40-08 Silverline Regulator delivers unmatched reliability and consistency. This two-stage regulator is designed to solve the common issue of delivery pressure rise as the cylinder pressure drops. By stepping down the pressure in two stages, it maintains a steady output flow from the moment you open a full tank until it is nearly empty. This feature is particularly valuable in precision welding, brazing, or laboratory applications where consistent flow is non-negotiable.

Built to last, the 223-40-08 features a plated body and bonnet. This plating not only gives the regulator a professional, clean appearance but also provides significant protection against corrosion and harsh shop or lab environments. The internal components are equally robust, featuring a stainless steel diaphragm that offers superior sensitivity and longevity compared to standard neoprene diaphragms. This metal diaphragm is key to maintaining high purity levels, making this regulator suitable for specialty gas applications where maintaining the chemical integrity of the gas is essential.

The unit comes equipped with a CGA 540 inlet connection, standard for oxygen service, and features a 1/4" FNPT outlet with a needle valve for fine flow adjustments. The large, easy-to-read 2-1/2 inch gauges allow for quick verification of tank and delivery pressure. Additionally, the automatic reseating safety relief valve provides peace of mind by protecting the regulator from pressure spikes. Whether you are setting up a high-end TIG station requiring ultra-pure gas or managing a laboratory gas manifold, the Miller Smith Silverline series offers the durability and precision required for the job.
