 Features - Reliable, repeatable sealing performance.
- O-ring seals to glass, metal, or plastic tubing.
- Knurled nut for easy, finger-tight assembly.
Testing
The ultra-torr vacuum fitting design has been helium leak tested to a maximum leak rate of 4 × 10–9 std cm3/s at ambient temperature. The leak rate increases as temperature increases due to permeation through the O-ring.
Cleaning and Packaging
Swagelok ultra-torr vacuum fittings are cleaned to remove machine oil, grease, and loose particles. For more information, see Swagelok Standard Cleaning and Packaging (SC-10).
