Component Specifications

Definition
Gas/Utility Connections are precision-engineered components designed to interface between external utility supply lines and cleanroom assembly station equipment. These connections ensure contamination-free transfer of gases (such as nitrogen, argon, compressed air) and utilities (like vacuum, deionized water, or electrical power) while maintaining the integrity of the cleanroom environment through sealed, particle-free designs that prevent ingress of contaminants.
Working Principle
These connections operate by creating hermetic seals between supply lines and equipment using specialized fittings (such as VCR, face seal, or quick-disconnect types) with gaskets or metal-to-metal seals. They maintain pressure integrity, prevent leaks, and filter particulates through integrated filtration elements. Automatic shut-off valves activate during disconnection to prevent backflow contamination.
Materials
Stainless steel (316L or 316Ti), electropolished surfaces, PTFE or Kalrez seals, brass with nickel plating for non-critical applications, aluminum alloys with anodized coating.
