Miller Smith Silverline 620 Series High Purity Oxygen Regulator, 2-Stage, 0-250 PSI

Reliable Oxygen Delivery with Miller Smith Quality

For welders and industrial fabricators requiring precise oxygen control, the Miller Smith 623-00-08-00-00 Silverline Regulator delivers superior performance. Part of the renowned 620 Silverline Series, this two-stage regulator is built to handle the rigors of daily use while providing the accuracy needed for specialized applications. With a CGA 540 connection, it is ready for standard oxygen cylinders and is rated for a maximum inlet pressure of 3500 PSI.

Consistent Pressure for Critical Work

Inconsistent gas flow can ruin a weld or cut, leading to costly rework. The two-stage architecture of this Miller Smith regulator solves this problem by stepping down pressure in two phases. This ensures that the delivery pressure stays at your set point—up to 250 PSI—even as the tank pressure drops. Whether you are running a precision cutting torch or supplying oxygen to a specialized welding setup, you can trust this regulator to provide a smooth, non-fluctuating flow.

Built to Last

Durability is a hallmark of Miller Smith equipment. This unit features a body machined from brass bar stock and finished with nickel plating, providing a tough exterior that resists wear and corrosion. The internal components are equally robust, featuring a stainless steel diaphragm that offers a longer service life compared to rubber alternatives. The 2-1/2 inch single scale gauge is easy to read, allowing operators to monitor pressure at a glance.

Designed for Safety and Integration

The 623-00-08-00-00 is designed with industrial safety in mind. It includes capturable vents that can be piped to a safe location, a critical feature when working in confined spaces or with specific safety protocols. The regulator's ability to withstand vacuum purging makes it adaptable to sophisticated gas management systems. Whether mounted directly to a cylinder or panel-mounted via its threaded bonnet, this regulator integrates seamlessly into your professional workflow.
