123-0006 - Miller Smith Silverline 120 Series Two-Stage Regulator CGA 350 250 PSI

Precision Two-Stage Gas Control

The Miller Smith 123-00-06 Silverline Series Regulator is a premium two-stage gas control device designed for applications requiring unwavering delivery pressure. Engineered for use with gases utilizing a CGA 350 connection—typically Hydrogen, Methane, and other specific fuel gases—this regulator maintains a constant output even as the supply cylinder drains. This feature is critical for laboratory settings, analytical instruments, and precision manufacturing processes where pressure fluctuation can compromise results.

Rugged Construction & Reliability

Built to withstand the rigors of industrial environments, the 123-00-06 features a body and bonnet machined from solid brass bar stock. The entire assembly is plated to provide superior protection against corrosion and wear. Inside, Miller Smith's proprietary Sure-Seat technology employs a filtered seat design that prevents microscopic debris from entering the seating area. This innovation drastically reduces maintenance requirements and extends the operational life of the regulator, ensuring gas stream purity and reliable performance over time.
