Overview
The Matheson 1L350 is a dual-stage gas pressure regulator designed for dependable pressure control in laboratory, medical, and industrial gas distribution systems. Paired with the included Matheson 63-3133 gauge, this regulator assembly provides accurate pressure monitoring and adjustable output for gases at inlet pressures up to 3000 psi. Dual-stage design maintains consistent outlet pressure as cylinder pressure declines, making it ideal for continuous or intermittent gas delivery applications.
Key Features
- Dual-stage design maintains stable outlet pressure despite declining inlet pressure
- CGA 350 connection for compatibility with standard high-pressure cylinders
- Integral 63-3133 gauge for real-time pressure monitoring
- Adjustable delivery pressure output up to approximately 400 psi
- Brass construction for standard industrial and laboratory use
