Product description
FST Unival II consists of graphite- impregnated PTFE yarn. Due to its special braid structure, the advantages that this material offers (low thermal expansion and excellent heat conduction) are optimally exploited.
FST Unival II is a very flexible packing and seals reliably with a minimum of gland pressure, even against thin liquid media that have a tendency to creep. It can also withstand dry friction up to a certain limit.
FST Unival II combines all the advantages of a low priced packing, that withstands all chemically and dynamically demanding conditions in pumps, mixers, kneaders, agitators and dryers.
