High Purity & Cleanliness

The internal surface is electropolished to a low Ra value, minimizing particle traps and outgassing for processes sensitive to contamination.

Reusable Connection

The nut-and-ferrule system allows for multiple make-and-break cycles while maintaining a reliable seal, simplifying maintenance.
