Graphite / PTFE Packing

Style 2024 - Graphite/PTFE Packing

Phelps Style 2024 is comparable to GFO® fiber in performance but at a lower cost - Testing between 2046 and GFO® fibers show equivalent performance - Tests include leak rate, heat transfer and elevated temperature yarn shrinkage.

Centerlock® braided from pure CPL fiber - Carbon, a high purity graphite;PTFE; and high temperature inert Lubricant. This unique packing has a graphite content of over 50%. The end result of this high graphite content is longer wear, better heat transfer, and a broad pH range. Less than 50% PTFE in the yarn makes this packing kinder to the shaft while retaining good abrasion resistance.

GFO® is a registered trademark of W.L. Gore & Associates. Centerlock® is a registered trdemark of Phelps Industrila Products
