612-00000000 - Miller Smith 610 Series High Purity Brass Regulator, 100 PSI, 1/4 FNPT Ports

Technical Overview of the Miller Smith 612 Series Regulator

The Miller Smith 612-00-00-00-00 is a premium component within the 610 Series Silverline family, engineered specifically for high purity gas delivery systems. This single-stage regulator is constructed from brass nickel-plated bar stock, providing a robust housing that resists environmental corrosion while maintaining a professional aesthetic suitable for laboratory environments. The core of its performance lies in the stainless steel diaphragm, which utilizes a metal-to-metal seal against the body. This design architecture eliminates the need for elastomeric seals in the gas stream, significantly reducing the potential for molecular outgassing and ensuring that the purity of the supply gas is maintained from the cylinder to the application point.

Designed for non-corrosive specialty gases, this unit features a maximum inlet pressure rating of 3500 PSI. The delivery pressure is adjustable up to 100 PSI, monitored via a 2-1/2 inch single scale gauge for clear readability. A critical technical feature is the inclusion of a 316 stainless steel filter located at the seat assembly; this filter traps particulate matter, protecting the seat from damage and ensuring consistent regulation performance over the lifespan of the device. The regulator is equipped with 1/4 inch FNPT inlet and outlet ports, offering maximum flexibility for installation into hard-piped systems, panel mounts, or custom manifolds where standard CGA connections are not required.

Safety and venting are addressed through a threaded bonnet which includes a 1/16 inch FNPT port. This allows for the capture and safe venting of gases in the unlikely event of a diaphragm failure, a standard requirement for many hazardous or enclosed environment applications. The unit is also tapped for rear panel mounting, facilitating organized and secure installation in gas cabinets or control panels.
