120-4006 - Miller Smith Silverline 2-Stage Hydrogen Regulator 0-30 PSI

Precision Pressure Control for Industrial Gases

The Miller Smith 120-40-06 Silverline Series General Purpose Two Stage Regulator is engineered for applications demanding unwavering delivery pressure. Unlike single-stage counterparts that may allow outlet pressure to drift as the supply cylinder depletes, this two-stage unit maintains a constant set pressure throughout the life of the cylinder. This feature is particularly vital in laboratory settings, testing facilities, and precision maintenance shops where consistency is non-negotiable.

Constructed from rugged brass bar stock, the body and bonnet are plated for superior protection against corrosion and wear. The internal mechanism features a large 1-7/8 inch diaphragm, which provides exceptional sensitivity and precise control over the 0-30 PSIG delivery range. The regulator is equipped with a CGA 350 inlet connection, specifically designated for flammable gases such as Hydrogen and Methane. Operators should verify their cylinder fittings match this standard before purchase.

Durability is a core component of the Silverline Series. The regulator incorporates Sure-Seat technology, utilizing a filtered seat to trap particulates that could otherwise compromise the seal or gas purity. This design significantly extends the service life of the unit by preventing seat degradation. With a maximum inlet pressure rating of 3500 PSIG, it is compatible with high-pressure cylinders, ensuring versatility across various industrial setups. The unit also features large, easy-to-read 2-1/2 inch gauges, allowing operators to monitor tank and delivery pressure at a glance.

Note: While the Silverline series is described as general purpose for inert gases, this specific SKU (120-40-06) is configured with a CGA 350 fitting. It is not suitable for Argon (CGA 580) or CO2 (CGA 320) cylinders without dangerous and non-compliant adapters. Always use the correct regulator for the specific gas service.
