632-4200 - Miller Smith Silverline 630 Series Two-Stage Lecture Bottle Regulator, 0-50 PSI

Miller Smith Silverline 632-42-00: The Lab Standard

When precision is non-negotiable, the Miller Smith 632-42-00 Silverline High Purity Regulator stands out as a top-tier choice for lecture bottle applications. This two-stage regulator is designed to take the guesswork out of gas delivery. Unlike single-stage regulators that allow delivery pressure to creep up as the cylinder empties, this two-stage model compensates for inlet pressure changes, providing a rock-steady output from start to finish. This feature is essential for welders and technicians performing delicate lab work or calibration tasks where consistency is key.

Built for Durability and Purity

Don't let the refined look fool you; this regulator is built tough. The body is machined from solid brass bar stock and finished with a high-quality plating that resists corrosion and wear. Inside, a 1-inch 316 stainless steel diaphragm ensures that your high-purity gases remain pure, preventing the contamination often associated with rubber diaphragms. The gauges are also chrome-plated, offering clear readability and resistance to the harsh environments often found in industrial workshops and testing facilities. With a maximum inlet pressure rating of 3500 PSI, it is versatile enough to handle a wide range of non-corrosive gas cylinders.

Precise Flow Control

The 632-42-00 is optimized for low-flow scenarios. It features a 0-50 PSI delivery range, adjustable via a large, ergonomic knob that makes dialing in the exact pressure simple, even when wearing gloves. The outlet is fitted with a high-quality stainless steel needle valve and a 1/8-inch tube fitting, giving you immediate and granular control over gas flow. This eliminates the need for bulky external valves and adapters, streamlining your setup.

Compact and Safe

Safety and convenience are built into the DNA of the Silverline series. The regulator includes a capturable preset safety relief valve, adding an extra layer of protection for both the equipment and the operator. Its slim profile is specifically engineered for lecture bottles, ensuring it doesn't make the cylinder top-heavy or awkward to handle. If you are working with specialty gases and need a regulator that combines the durability of industrial equipment with the precision of laboratory instruments, the Miller Smith 632-42-00 is the tool for the job.
