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 !
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” > thet do NOT require any metal “backing” ferrule ! . . . except for 1.5, 1.75, 2.0”ID where backing ferrule is required ( and uses less graphite to make ! )
*Custom Tooling Cost > ( <10mm ID) $75 ) 10-25mm ID $150 25--50mm $195 “once-off” charge if the size NOT already an in- stock item !
We will ask firm order(er)s to specify / verify the exact DIMs preferred and We THEN Supply OUR nearest “suitable” re OD /L /SL / ( “Tip” strengthened re fragility ! where necessary ! ) > else a Tooling Cost Applies INSUFFICIENT Details THEN > NO Order will be processed !
* YOUR Inaccuracies ? > NO Returns accepted !
