Jet Separator Ferrules

Glass Filled PTFE Ferrules - 250 °C

Constructed of Glass Filled PTFE
For vacuum sealing glass columns and jets to fittings
Maintains PTFE's sealing properties, but with less flow at high temperature
Does not flake like graphite and clog jets
Maximum usable temperature is 250 °C
Recommended for glass GC columns and jet separators
Two styles available: Type GTF requires a back ferrule, type OTF does not.
For 1/4 inch O.D. Glass columns and jets

GTF OTF

These ferrules are constructed from glass filled PTFE, giving the ferrules the sealing properties of PTFE but minimizing the flow problems normally encountered with pure PTFE. All ferrules fit the standard Swagelok, Parker, SGE and other GC fittings. Glass filled PTFE ferrules are ideal for use on mass spectrometer jet separators, glass and metal GC columns and for glass and fused silica capillary columns.

Graphitized Vespel Ferrules - 350 °C

These Vespel ferrules contain 15% graphite.

Because these ferrules are harder, they do not distort and flow as much as other types and are ideal for butt type connections where the flowpath might be interrupted. Greater care must be used when installing these ferrules due to their greater hardness to minimize glass jet breakage. However, these ferrules are usable up to 350 °C. Available in packages of 10.

Vespel Ferrules - 350 °C

These are natural or unfilled Vespel ferrules and are a harder material than our graphitized vespel ferrules. Therefore, extreme care must be used when using these ferrules. Vespel ferrules are not normally recommended for jet separators.

Note - Both types of Vespel ferrules form reliable seals, however, with extreme temperature cycling from 300 °C the ferrules may leak due to the natural hysteresis of Vespel. Available in packages of 10.

Graphite - Ferrules - 450 °C

Graphite ferrules are 99.95% pure graphite and are extremely easy to use, for obtaining reliable leak free connections. Because graphite does not stick or bind onto the tubing, graphite may be removed and reused. Graphite ferrules are used by many mass spec users on their jet separators due to their ease of removal. However, vacuum seals may not be as efficient as other types of ferrules. Available in packages of 10.
