Gas/Utility Connections: Temperature Range -40°C to 200°C

Q: What types of gases can these connections handle?

These connections are designed for high-purity gases including nitrogen, argon, oxygen, hydrogen, and specialty gases, as well as compressed air and vacuum systems.

Q: How do these connections prevent contamination in cleanrooms?

They feature electropolished surfaces, hermetic seals, integrated particulate filters, and automatic shut-off valves that prevent backflow and particle generation during connection/disconnection cycles.

Q: What maintenance is required for gas/utility connections?

Regular leak testing, particulate monitoring, seal replacement per manufacturer schedule (typically 12-24 months), and verification of pressure integrity using helium mass spectrometry.

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.
