Packing of fibrous PTFE yarn with incorporated graphite and soaked with silicon oil. Thanks to this composition braided packing is only slightly prone to squeezing out of the stuffing box and softly adheres to the shape of the stuffing box. Low friction coefficient and high thermal conductivity protect the package against overheating caused by high revolutions of the pump shaft. Thanks to all these characteristics the packing similar to packings of GFO at significantly lower price is obtained.
Recommended for use in stuffing boxes of pumps and fittings, with water, steam, oils, solvents, salts, acids and alkalis, with exception of very strong oxidants. The most popular of PTFE packings.
