Pure CPL Fiber

Centerlock® braided from pure CPL fiber. This packing is comparable to GFO® fiber  in performance but at a lower cost.

CPL fiber is made of: Carbon, a high purity graphite; Polytetrafluroethylene, PTFE; and high temperature inert Lubricant.

This unique packing has a graphite content of over 50%. That means CPL fiber is one of only two yarns to achieve this high graphite content. 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.

Best general service high speed pump packing Air, water, sea water, brines, superheated steam, sludges, slurries, waste, petroleum oils, petroleum fuels, solvents, chemicals, liquified gas.

Testing between CPL and GFO® fibers have shown the products are equivalent in performance. Tests include leak rate, heat transfer and elevated temperature yarn shrinkage.
