221-0000 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator 0-60 PSI

High-Performance Specialty Gas Regulation

When your welding or industrial application crosses over into the realm of high-precision analytical work, the Miller Smith 221-00-00 Silverline Regulator stands out as the tool of choice. While standard welding regulators are built for durability, this unit is built for precision and purity. It is part of the renowned 220 Silverline Series, designed to handle high-purity, non-corrosive gases used in specialized industrial processes and laboratory calibration. The defining feature of this model is its two-stage architecture. In critical applications, you cannot afford the delivery pressure to drift as your gas source depletes. This regulator steps the pressure down in two stages, guaranteeing a flat, stable output pressure throughout the entire life of the cylinder.

Rugged Construction, Refined Performance

Despite its delicate precision, the 221-00-00 is built on a foundation of rugged brass bar stock, which is then plated for superior protection. This plating isn't just for looks; it ensures the exterior remains free of oxidation and contaminants that could compromise a clean environment. Internally, the regulator utilizes a filtered seat to trap any particulate matter before it can damage the seating surface, significantly extending the service life of the unit. The stainless steel diaphragm offers precise control and excellent response to pressure changes, far surpassing standard elastomeric diaphragms found in general-purpose regulators.

Versatile Connectivity

Unlike standard regulators that come with fixed CGA connections, this model features 1/4" FNPT inlet and outlet ports. This universal porting allows you to adapt the regulator to virtually any non-corrosive gas cylinder or line system by simply installing the appropriate CGA nipple and nut or tube fitting. Whether you are setting up a gas chromatograph, a flame photometry station, or a specialized purging rig, the Miller Smith 221-00-00 provides the reliability and adaptability needed for high-stakes gas delivery. It supports a delivery range of 0-60 PSI, making it ideal for low-to-medium pressure applications requiring absolute stability.
