NO Tooling Costs Apply for “Standard” Ferrules . . .  > OR NON-Standard “negotiable”
> with YOUR Fitting sample & DIMS provided > but depending on difficulty !

  • Graphite Ferrules are UNIQUE
  • Soft > Malleable squash into Shape > in-situ !
  • DISCLAIMER > over-ride
    Thread & Inner profile of NUT invariably results in extrusion of the Graphite into the threads etc > some applications the ferrules may be marginally COMPROMISED re compression Density !
  • ASK > for recommendations in these “extreme” situations !
  • NOT All DIMS are in fact feasible
  • Custom Tooling : Small <1/2”ID $100; Large >1/2” - 2”ID $150 - IF required ? > ASK !
  • Limitations > Size vs Wall thickness vs Length
  • Graphite Ferrules are NOT machine as such \
  • > Soft / Malleabe & CAN be squashed in-situ into shape ( but marginally ? > by a few “thous” w/o losing integrity )
  • BUT High Compression Moulding in a Tooling “Die Ste”
    Extree Pressues used ( but Graphite is “elastic”) and the laminated format whilst a good compromise can still result in infusion leaks under high vacuum minimised by high torque tightening in a “truly captured” fitting format !
  • ALWAYS TRIAL TEST RE- SAFETY ! > & Can be highly APP DEPENDENT !
    re temperature and Pressure > Graphite has a LOW co-eff of friction !
    RE Supporting extreme weights in a Vertical position > Tube may tend to “slide” > out !
    > an EXTREME situation > TEST Safely . . . but Be-A-Ware !


NOTE : CHROMTECH is the ONLY known OEM of these Large Graphite Ferrules !

AND the “prime” Inventor of GFs for Chromatogtaphy Use ! ( from > ‘60s+ )
& the source of Many OEM “copycats” since !

APPS

  • General Purpose Ferrules -
  • Replaceable ( slides OFF! ), ( cost savings ! > eg for protypes & re-usable ! )
  • Reducing Ferrule Apps ( compared to expensive metal fittings )
  • Mainly Low(er) Pressure ! ( <<1000psi depending on size ? )
  • HIgh Temperature APPS >1000C in inert atmosphere ( furnace tubes )
  • Gas Chromatography Columns, Inlet Liners
  • Glass / Ceramic ( Catalyst )Tubes  > eg Gas Generators
  • HighTemp Spectra Cells “ Glass / Quartz { for  eg IR, FTIR
    ( higher VOCs >~C20 ))
  • -    where Size DIMs eg OD are far more critical to fit & seal !

In Fact

The UNIVERSAL Ferrule for many APPS
SOFT & Malleable material NOT Amorphous !

 where normal metal Ferrules are Useless
> & tend to break or distort glass, ceramic > metal tubing !

whats-more ! with care the GFs can be reused ! > & simply slide-off the tube

> leave the GF inside the “nut” do NOT require any metal “backing” ferrule !
