OVERVIEW

High Purity Gas Delivery for Critical Welds

When your welding or industrial process demands absolute gas purity, the Miller Smith 256-00-00 Silverline Regulator delivers. Designed specifically for liquid cylinders, this regulator ensures that your shielding or process gases reach the torch or equipment without contamination. In high-end TIG welding, laser cutting, or laboratory work, even microscopic impurities can ruin a weld or invalidate a test. This regulator combats that risk with a nickel-plated body and a stainless steel diaphragm, materials chosen specifically to prevent off-gassing and corrosion that standard brass regulators might introduce into the stream.

Engineered for Liquid Cylinders

Standard regulators can be awkward to fit onto liquid cylinders due to the orientation of the valves. The Miller Smith 256-00-00 features a back-mount (rear entry) inlet design that aligns perfectly with liquid cylinder outlets, creating a cleaner, safer, and more ergonomic setup. It controls the delivery of gas (vaporized from the liquid source), providing a steady output pressure between 0 and 500 PSI. This range is ideal for high-pressure supply lines or applications requiring higher flow rates than standard welding regulators provide.

Durability You Can Trust

Industrial environments are tough on equipment, but the Silverline series is built to last. The nickel plating protects the exterior from the harsh realities of shop environments, while the internal Sure-Seat™ filtered seat technology protects the internal mechanism. Debris and particles are the number one cause of regulator failure; the filtered seat traps these contaminants before they can score the seat and cause leaks or creep. Combined with easy-to-read 2-1/2 inch gauges and a built-in safety relief valve, this regulator offers the reliability, safety, and precision required for professional gas handling.

FAQ

The Miller Smith 256-00-00 has a delivery pressure range of 0-500 PSIG.

This regulator is designed to control the delivery of gas (vapor). It connects to liquid cylinders but regulates the gas phase, not the liquid phase.

It features a 1/4" FNPT rear entry (back mount) connection, which is standard for many liquid cylinder setups or allows for custom fitting adaptation.

The 1-7/8" stainless steel diaphragm provides precise pressure control and is non-contaminating, making it ideal for high purity and cryogenic applications where rubber diaphragms might degrade or off-gas.

Yes, it is covered by the Miller True Blue Warranty. Please refer to the specific warranty documentation for duration and terms.

Sure-Seat™ is a filtered seat design that prevents contamination from entering the seating area, reducing wear, repair costs, and downtime.

While the nickel plating and stainless diaphragm offer good resistance, this regulator is primarily designed for high purity inert and semi-inert gases. Always check material compatibility for specific corrosive gases.

The maximum inlet pressure for this regulator is 3500 PSIG.
