GRAPHITED PTFE WITH KEVLAR GLAND PACKING

Material： Graphite PTFE line、 Kevlar fiber line.

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.
