312-00320000 - Miller Smith Silverline 310 Series High Purity Stainless Steel Regulator CGA 590

Durable Stainless Steel Regulation for Industrial Environments

When your welding or industrial application involves corrosive environments or requires absolute gas cleanliness, the Miller Smith Silverline 312-00-32-00-00 Regulator is the professional's choice. Built to withstand the toughest conditions, this regulator is machined from 316 stainless steel bar stock, offering superior resistance to external corrosion and internal chemical attack. It is specifically designed for use with CGA 590 cylinders, commonly used for industrial air and specific specialty gas mixtures, providing a stable delivery pressure of up to 100 PSIG.

Reliability is at the core of the Silverline series. The single-stage design utilizes a convoluted stainless steel diaphragm that provides accurate pressure regulation while eliminating the risk of rubber contamination found in standard brass regulators. This makes it an excellent option not just for high-purity welding shielding gases, but also for maintenance, repair, and operations (MRO) tasks where equipment longevity is a concern. The large, 2-1/2 inch gauges are easy to read from a distance, allowing operators to monitor cylinder and delivery pressure at a glance, ensuring seamless workflow and safety.

Safety features are integrated directly into the build. The regulator includes a captured vent port in the bonnet, which allows for the safe diversion of gases if the diaphragm is compromised—a crucial feature when handling toxic or reactive substances. The 316 stainless steel filtered seat prevents particulate damage, extending the lifespan of the regulator and reducing downtime for repairs. Whether mounted on a cylinder or installed in a panel system, this Miller Smith regulator provides the consistent performance and rugged durability that professional welders and facility managers demand.
