123-0000 - Miller Smith Silverline 2-Stage General Purpose Regulator, 250 PSI, 1/4 FNPT

Precision Gas Control for Industrial and Laboratory Applications

The Miller Smith 123-00-00 Silverline Series General Purpose Two Stage Regulator is engineered to provide exceptional pressure stability and control for a variety of inert and non-corrosive gases. Designed for professionals who demand accuracy, this regulator features a robust two-stage architecture. Unlike single-stage models that allow delivery pressure to rise as the supply cylinder empties, the 123-00-00 maintains a constant output pressure throughout the life of the cylinder. This feature is critical for laboratory applications, calibration stations, and precision manufacturing processes where pressure fluctuation can compromise results.

Constructed from high-quality brass bar stock, the body and bonnet are built to withstand the rigors of daily industrial use. The entire assembly is plated to provide superior protection against corrosion and wear, ensuring the unit remains operational and legible in challenging environments. The regulator is equipped with a large 1-7/8 inch diaphragm, which enhances sensitivity and allows for fine-tuning of delivery pressure up to 250 PSI. This specific model is outfitted with 1/4" FNPT inlet and outlet connections rather than standard CGA fittings, making it uniquely suited for line regulation, panel mounting, or integration into custom manifold systems where specific plumbing requirements must be met.

Reliability is further enhanced by Miller Smith's Sure-Seat technology. This filtered seat design prevents microscopic particles and contaminants from entering the high-pressure seat area, a common cause of regulator failure and creep. By protecting the seat, the regulator ensures gas stream purity and significantly extends the service interval. Whether controlling Nitrogen, CO2, Argon, or industrial Air, the Miller Smith 123-00-00 delivers the consistent performance required for critical gas management tasks.
