Gas fittings: Chromatograph and Sputtering

Click For Summary
SUMMARY

The discussion centers on the restoration of the Plasma Sciences CrC-150 Sputtering system, specifically focusing on the identification of gas fittings. The user, Mike, seeks assistance in identifying brass compression fittings with a 1/4" mean thread diameter and mentions previous use of a 1/16" or 1/8" stainless steel tube with stainless steel nuts and graphite ferrules, typically associated with gas chromatographs. A solution was provided, identifying the required fitting as a 1/8" Swagelok tube fitting, with gratitude expressed towards a representative from Torr for their assistance.

PREREQUISITES
  • Understanding of gas fitting components, specifically brass compression fittings.
  • Familiarity with Swagelok tube fittings and their applications.
  • Knowledge of gas chromatography and its associated hardware.
  • Basic skills in working with sputtering systems and their maintenance.
NEXT STEPS
  • Research the specifications and applications of Swagelok tube fittings.
  • Explore options for gas dryers and purifiers suitable for sputtering systems.
  • Investigate the compatibility of stainless steel nuts and graphite ferrules with various gas fittings.
  • Learn about the maintenance and troubleshooting of Plasma Sciences sputtering systems.
USEFUL FOR

This discussion is beneficial for engineers, technicians, and researchers involved in sputtering system maintenance, gas chromatography, and those seeking to optimize gas fitting configurations in laboratory settings.

Hello,

I'm attempting to restore my Plasma Sciences CrC-150 Sputtering system, and I'm having a terrible time working out the source gas fittings.
Each is a brass compression fitting with a roughly 1/4" mean thread diameter.

The last time I used this machine, a chemist helped me by assembling a 1/16" or 1/8" stainless steel tube with stainless steel nuts and graphite ferrules. At the time he said the components were normally used for his gas chromatograph.

I'd greatly appreciate help identifying these parts as well as finding a reasonably priced gas dryer/purifier and associated adapters.

Thanks in advance,

Mike

Hah! It was a 1/8" swagelok tube fitting.
Many thanks to a young man at Torr for getting me the answer.

Stay Warm My Friends,

Mike
