Graphite/Polyimide
- Do up finger-tight - then requires 1/2 turn with spanner . Feel is relatively progressive until max pressure with short spanners ( Go by feel until silica in ferrule doesn't slip )
Note : the silica is almost impossible to break inside the ferrule
NEW ! 2005 Graphite/Polyimide now in SHORT Version ( similar to Agilent short GFs )
Works perfectly in standard Swagelok 1/16" Nut - Price 25% less use eg
Cat# SF0.4VG
Standard Sizes for 1/16"OD Ferrules - most capillary columns
