623-84060000 - Miller Smith Silverline 620 Series High Purity 2-Stage Regulator CGA 350

Reliable Gas Delivery for Industrial and Specialty Use

When your work involves specialty gases like Hydrogen or Methane, you need a regulator that combines industrial durability with laboratory-grade precision. The Miller Smith 623-84-06-00-00 Silverline Regulator is built to handle the demands of high-purity gas delivery systems. Featuring a CGA 350 connection, this two-stage regulator ensures that your delivery pressure remains rock-steady at your set point (up to 250 PSI), regardless of how full or empty your supply cylinder is. This eliminates the need for constant adjustments at the tank, allowing you to focus entirely on your process, whether it's specialized welding, heating, or running analytical equipment.

Durability is built into every component of the 620 Silverline series. The body is machined from brass bar stock and nickel-plated, providing a tough exterior that stands up to shop environments while maintaining a clean, professional appearance. Inside, a stainless steel diaphragm replaces the traditional rubber components found in standard regulators. This not only improves the accuracy of your pressure settings but also prevents the diaphragm from absorbing or releasing contaminants into your gas line. A 316 stainless steel filter protects the seat from debris, further extending the lifespan of the unit and reducing maintenance downtime.

Safety is a priority when handling flammable gases associated with CGA 350 fittings. This regulator includes threaded front and rear bonnets for panel mounting options and features a captured vent port. This allows you to connect a vent line to pipe gases safely away, providing peace of mind in enclosed spaces. The large 2-1/2 inch gauges are easy to read from a distance, giving you instant visual confirmation of your tank and line pressure. Whether you are setting up a laser cutting station, a laboratory supply line, or a specialized manufacturing process, the Miller Smith 623-84-06-00-00 delivers the consistent performance and safety features professional welders and technicians trust.
