GAS STICKS & PANELS
Precision Components for High Purity and Ultra-High Purity Gas Delivery Systems
At the core of every high-functioning gas delivery system are two essential components: gas stick assemblies and gas panels. Whether you're distributing hazardous, inert, or specialty gases, CSI's precision-built sticks and panels ensure safe, clean, and efficient gas flow from source to tool.
As an ISO-certified manufacturer with over two decades of experience, Critical Systems, Inc. offers industry-leading ultra-high purity gas sticks and UHP gas panels that meet the highest standards in safety, design, and contamination control.
Whether you're upgrading your existing gas delivery infrastructure or building a new high-purity system from scratch, CSI’s gas sticks and gas panels offer a modular, code-compliant, and performance-optimized solution.

GAS STICKS
Streamlined Distribution from Panel to Process
CSI’s gas sticks are modular, scalable assemblies that connect a centralized panel to multiple tool endpoints with consistency and precision. Engineered for reliability, our sticks are rigorously tested and validated for use in critical applications, including semiconductor manufacturing, pharmaceuticals, and high-purity R&D facilities.
Available in ultra-high purity, high purity, and general-purpose configurations, each gas stick is constructed from corrosion-resistant materials and undergoes full analytical testing before deployment.
CSI’s gas stick assemblies are designed to support modular upgrades and line expansions, making them ideal for growing or high-turnover facilities.
Features
Compact, Compliant, and Engineered for Purity
Our gas panels serve as the central distribution point for high purity and ultra-high purity gas systems. As a full-service UHP fabrication shop, CSI delivers gas panels that are SEMI S2 certified and fully customizable to your facility’s needs. Every panel is built to ensure maximum process gas purity, with orbital welding and UHP-grade componentry throughout.
Whether you need a single-stage manual panel or a fully automated auto-crossover configuration, our systems are optimized for performance, accessibility, and space efficiency.
