OVERVIEW

Reliable Control for Liquid Cylinders

When you are working with liquid cylinders for your welding or industrial gas supply, you need a regulator that fits right and lasts long. The Miller Smith 255-20-09 Silverline regulator is built exactly for this purpose. Unlike standard regulators that mount on the side, this unit features a back-mount (rear entry) connection. This design allows it to sit flush and secure on your liquid cylinder, keeping your setup clean and reducing the risk of accidental damage to the stem or gauges.

This regulator isn't just about fit; it's about performance. It comes equipped with a CGA 580 connection, perfect for your Argon, Nitrogen, or Helium supply. Whether you are running a high-purity purge for TIG welding or supplying gas to a laser cutter, the 0-350 PSI delivery range gives you the pressure you need with excellent stability. The large 2-1/2 inch gauges are easy to read, so you can check your tank levels and line pressure at a glance without squinting.

One of the biggest enemies of gas equipment is corrosion and wear. Miller Smith has addressed this by nickel-plating the entire body and bonnet. This tough finish keeps the regulator looking new and fighting off rust and grime in shop environments. Inside, a stainless steel diaphragm handles the cold temperatures of cryogenic gas expansion without cracking or losing flexibility, ensuring that your gas flow remains smooth and consistent day in and day out. Plus, the filtered Sure-Seat™ system keeps dirt out of the critical sealing areas, meaning fewer repairs and more uptime for your shop.

Key Applications:

  • High purity gas distribution
  • Liquid cylinder (dewar) gas withdrawal
  • Laboratory and analytical systems
  • Industrial laser assist gas supply

FAQ

This regulator features a CGA 580 inlet connection, which is standard for inert gases like Argon, Nitrogen, and Helium.

This regulator is designed to control the delivery of gas, not liquid. It connects to the gas use port of a liquid cylinder.

The Miller Smith 255-20-09 has a delivery pressure range of 0-350 PSI.

The rear-entry (back mount) design is specifically engineered for liquid cylinders to allow the regulator to mount correctly and safely without awkward angles.

It utilizes a large 1-7/8 inch stainless steel diaphragm, which is essential for maintaining performance in cryogenic applications.

Yes, it includes a built-in capturable preset safety relief valve for added safety.

No, this regulator has a CGA 580 connection. Oxygen cylinders require a CGA 540 connection. Never use adaptors to force a connection for incompatible gases.

The nickel-plated body, bonnet, and gauges provide superior corrosion resistance and extend the service life of the regulator in harsh environments.
