255-2008 - Miller Smith 250 Series Silverline High Purity Regulator CGA 540

Reliable Gas Control for Liquid Cylinders

When your operation depends on the consistent flow of gas from liquid cylinders, the Miller Smith 255-20-08 Silverline Regulator delivers the performance you need. Designed for professionals in welding, laboratories, and bulk gas distribution, this regulator combines heavy-duty construction with high-purity features. It is built to handle the rigors of industrial environments while providing the precision required for analytical work. With a CGA 540 connection and a delivery range up to 350 PSI, it is the ideal choice for oxygen and compatible specialty gas applications.

Built to Last in Tough Environments

Corrosion and wear are the enemies of any gas equipment. The Miller Smith 255-20-08 fights back with a fully nickel-plated body, bonnet, and gauges. This protective coating ensures your regulator stays clean and functional, even in challenging shop conditions. The internal components are just as tough; the 1-7/8 inch stainless steel diaphragm is engineered to withstand the thermal stresses of cryogenic applications, providing a service life that outlasts standard rubber diaphragms. Whether you are running a laser cutter or supplying a lab manifold, this regulator is built to keep running.

Smart Features for Easy Operation

Time is money, and this regulator is designed to save you both. The rear-entry inlet allows for a clean, streamlined connection to liquid cylinders, preventing awkward hose routing. The large, 2-1/2 inch gauges are clear and easy to read, so you can check your pressure settings at a glance without squinting. Inside, Miller's patented Sure-Seat™ technology filters out dust and debris before it can damage the valve seat. This means fewer leaks, fewer repairs, and more time spent getting work done.

Safety and Precision

Safety is never optional. This Silverline series regulator includes a built-in capturable preset safety relief valve to prevent over-pressurization. The single-stage design offers stable pressure control for gas withdrawal, ensuring your downstream equipment receives a steady flow. Upgrade your liquid cylinder setup with a regulator that offers the perfect balance of durability, precision, and safety.
