Graphite packing is mainly made of various reinforced fibers, steel wire, copper wire, nickel wire, carbon fiber, pre-oxygen wire,
glass yarn, etc. . Suitable for dynamic seal under high temperature and high pressure. In addition to a small number of strong
oxidants, it can be used to seal hot water, superheated steam, heat transfer fluids, ammonia solutions, hydrocarbons, cryogenic
liquids and other media, mainly, used for sealing valves, pumps and reaction vessels under high temperature, high pressure and
corrosion resistant media. It is also a unique versatile seal packing.

Usage:It combines mechanical strength with surface lubricity to give a long lasting, high performance sealing, near universal packing, for use in all rotary, reciprocating and static gland applications.

It combines the benefits of the remarkable properties of two outstanding gland packing fibers. GFO has the best combination of features of any packing fiber but it may extrude or deteriorate in high mechanical loading conditions. The addition of DU PONT’S KEVLAR adds steel-like strength. KEVLAR is square inter-braided to add the strength of KEVLAR where it is most needed on the corner-posts. KEVLAR fibers are specially braided from the core to the corner-posts for dimensional stability and to resist extrusion. The GFO yarns are braided to the packing surfaces to enhance smooth running and sealing capability.

The packing is for extended life in high pressure or mechanical load conditions, particularly on worn or large tolerance equipment and in the most demanding chemical environments. Shaft wear is virtually eliminated, and high speeds and aggressive chemicals can be handled, because of the presence of GFO on the sealing faces. Extrusion and gland maintenance is negligible, even in the most arduous of applications, due to the inter-locked braising of KEVLAR.
