Tescom 44-2363-24 is a single-stage backpressure regulator

Description:
The product is from the TESCOM™ 44-2300 Series designed to provide precise and reliable control of low-flow gas pressure in specialty, industrial, and analytical applications. Its diffusion-resistant metal diaphragm seal ensures gas purity and integrity while maintaining stable regulated pressure. The unit’s compact, lightweight design makes it ideal for installation in systems where space is limited yet reliable pressure control is required.

Key Features:
- Reduces contamination and ensures accurate regulation of corrosive and non-corrosive gases. 
- Convoluted metal-to-metal sealed diaphragm maintains gas purity and structural integrity. 
- Close pressure differential between crack and reseat for precise pressure control. 
- Compact and economical design suitable for OEM and laboratory systems. 
- Optional dome loading for enhanced outlet pressure control. 
- Panel mounting available for easy installation.
