Abrasive, Chemical & Extrusion Resistant Packings
 
C1061/C1064/C1065P/C1072

John Crane styles C1061, C1064, C1065P, and C1072 are ideal for abrasive services where packing extrusion and sleeve or shaft wear are a concern. These products maintain structural and dimensional stability, offering enhanced performance due to the combination of high quality fibers constituting body construction and the reinforcement of carefully selected aramid or polyimide fiber external corners.


These styles also feature chemical resistance and reduced hardware damage as opposed to packings constructed of high percentage aramid fibers.

 
Design Features
 

C1061
A combination of PTFE impregnated synthetic and aramid fibers offering the extrusion and abrasion resistance ideal for general service.

C1064
A combination of graphite impregnated PTFE and aramid fibers offering the extrusion and abrasion resistance ideal for a wide range of abrasive and chemical services.

C1065P
A combination of graphite impregnated PTFE and polyimide fibers resulting in a high chemically resistant packing with non-scoring abrasion resistant corners.

C1072
A combination of non-contaminating virgin PTFE and aramid fibers offering the extrusion and abrasion resistance ideal for a wide range of abrasive and chemical services

Applications
Dynamic/abrasives, water, chemicals, acids, medium caustics, corrosives, gases, air, oils, steam, solvents, wastewater, slurries, paper stock, liquors, asphalt, fly ash, and condensate.

Standard Sizes
Styles C1061, C1064, C1065P, and C1072 are available in standard cross-section sizes from 1/4" to 1" in 1/16" increments.
