222-2005 - Miller Smith Silverline 220 Series High Purity 2-Stage Regulator CGA 346

Reliable Gas Delivery for Critical Tasks

When your work depends on the accuracy of your gas supply, the Miller Smith 222-20-05 Silverline Regulator is the tool you can trust. Designed for high-purity applications, this regulator takes the guesswork out of gas control. Unlike single-stage regulators that require frequent adjustment as the tank empties, this two-stage powerhouse maintains a steady output pressure from the moment you crack the valve until the cylinder is ready for a change-out. This "set it and forget it" reliability is essential for professionals managing sensitive calibration mixtures or carrier gases.

Durability meets precision in the Silverline 220 Series. The regulator is constructed from rugged brass bar stock, ensuring it can withstand the physical demands of industrial and laboratory environments. However, it doesn't sacrifice sensitivity for strength; the stainless steel diaphragm reacts instantly to changes in flow, providing smooth and accurate delivery. The entire unit features a plated finish, protecting it from oxidation and wear, ensuring it looks and performs like new for years. The included 1/4-inch MNPT needle valve allows for fine-tuning of the outlet flow, giving you complete control over your system.

This specific model comes equipped with a CGA 346 fitting, making it compatible with standard compressed air cylinders used in analytical setups. It is rated for a maximum inlet pressure of 3500 PSIG and delivers a consistent 0-100 PSIG output. Safety is built right in with an automatic reseating relief valve, providing peace of mind during operation. For welders and technicians who occasionally cross over into analytical work or require high-purity air for specific processes, the Miller Smith 222-20-05 offers the perfect blend of industrial toughness and laboratory-grade precision.
