• Designed to be retightened after initial temperature cycles to avoid leaks
• Graphite ferrules do not shrink in use but are very soft and must be packed and handled with care
• Long lifetime
• MS compatible

Recommended applications

• General purpose for glass packed & capilliary column
• MS and oxygen sensitive detectors

Trajan CRS 85% polyimide Vespel® / 15% graphite ferrules are designed to be used in GC/MS interface applications because they are non-porous to oxygen. They can be reused and repositioned along capillary columns if not over-compressed in the fitting.

* Softer than 100% Vespel, only gentle force is needed to compress them and form a seal.

Rated to 400°C.
