321-81240000 - Miller Smith 320 Silverline High Purity 2-Stage SS Regulator, 50 PSI, CGA 580

Uncompromising Quality for Critical Gas Control

When your work demands absolute precision and cleanliness, the Miller Smith 320 Silverline Series High Purity Regulator delivers. This model, the 321-81-24-00-00, is a top-tier two-stage regulator designed for professionals who cannot afford fluctuations in gas pressure or contamination in their lines. Built from high-grade 316 stainless steel, it offers superior durability and corrosion resistance, making it the ideal choice for harsh environments or when working with specialty gases that might degrade standard brass regulators.

The two-stage design is a game-changer for consistency. In single-stage regulators, the outlet pressure can creep up as the tank empties, requiring constant manual adjustments. This Miller Smith regulator eliminates that hassle by stepping down the pressure in two stages, ensuring that your delivery pressure stays locked at your set point—in this case, up to 50 PSI—regardless of how much gas is left in the cylinder. This "set it and forget it" reliability allows you to focus on your process, whether you are running a TIG welding setup requiring ultra-pure argon or managing a laboratory gas manifold.

Visibility and safety are key components of the 320 Series. The regulator comes equipped with large, easy-to-read 2-1/2 inch gauges that let you check your tank levels and output pressure at a glance. For added safety, especially when working in confined spaces or with potentially hazardous gases, the bonnet features captured vent ports. These allow you to pipe any vented gas away from the user, adding an extra layer of protection. The stainless steel diaphragm provides a metal-to-metal seal, ensuring that no outside air leaks in and no gas leaks out, preserving the integrity of your work.

This specific model comes with a CGA 580 connection, the standard for inert gases like Argon, Nitrogen, and Helium, and features a 1/8" tube fitting on the outlet for precise connections to your equipment. It is designed to handle inlet pressures up to 3500 PSI. If you are looking for a regulator that combines industrial-strength durability with laboratory-grade precision, the Miller Smith 321-81-24-00-00 is the tool you need to get the job done right, every time.
