3R 720
BRAIDED PACKING
PTFE YARD, DRY

ISO 9001 : 2000 Certified
 

3R 720 packing is a firm, high density interlock braided packing manufactured from pure PTFE filaments pretreated with PTFE dispersion, but contains no other lubricants. The PTFE dispersion provides a low friction surface finish and prevents leakage through the braid.
 

Applications //

3R 720 packing is especially suited for oxygen service and other services where lubricants other than PTFE can not be tolerated. 3R 720 is commonly used in valves and lower shaft speed applications. It is resistant to most chemicals, aggressive fluids, gases and solvents, with the exception of molten alkali metals.
