Airgas Dual Stage Regulator Kit CGA 346 100 PSIG

The Airgas (Part Number Y12LEBMEQ346-AG) Dual Stage Regulator Kit is a high-precision pressure control system designed for analytical and high-purity gas applications. Based on the part number and industry standards for the Y12 series, this specific configuration is engineered for use with Compressed Air (CGA 346) cylinders.

Key Specifications:

Connection: CGA 346 Inlet (Standard for Industrial/Breathable Air up to 3,000 psig).

Delivery Pressure: 0 to 100 PSIG. The dual-stage design ensures that this delivery pressure remains constant even as the cylinder pressure decays from full to empty, eliminating the "decay effect" common in single-stage units.

Valve Type: Equipped with a 1/4 Turn Diaphragm Valve (Packless) on the outlet. This quick-action isolation valve allows for immediate flow control and ensures high system purity by eliminating the stem packing found in standard needle valves.

Construction: Typically features a Nickel-Plated Brass body with Stainless Steel diaphragms. This metal-to-metal seal construction prevents outgassing and contamination, making it suitable for high-purity carrier gases or zero-air generators.

Kit Components: The "-AG" suffix denotes a complete "Ready-to-Use" kit that includes the regulator, the outlet valve, and potentially relief valves or specific compression fittings (e.g., 1/4" tube fitting) pre-installed for immediate integration into laboratory piping.
